Chromecast Not Connecting to Comcast Modem - Google Chromecast

I have a Chromecast that will not make a connection to WiFi. You can see it on the network, but when going through the final steps I am told that it cannot communicate with the Chromecast and it times out. Can anyone provide some suggestions?
I am using modem for business class.

You may have tried this already, but did you try power cycling the modem?

Yes, tried everything!

is it possible to turn off AP isolation?

Something that may or may not apply to your situation but should be noted...
Comcast is currently (in some areas) running two Wireless Networks off the router they give you for your home service.
One is for their Public WiFi use (which I believe requires a Comcast login)
and the other for your own local network use.
Is it possible that you are trying to connect to the public SSID and not the local?
Do you see two different SSIDs available?
Otherwise the best suggestion is to call Comcast and let them walk you through it.
I personally never allow my ISP to control my wireless or router and insist they put their equipment into Bridge mode.
If you are having problems just connecting I can't imagine what kind of other issues you are going to face with settings needed for a good CCast experience.

This explains the numerous open xfinitywifi APs I've been seeing lately... Glad I have my own modem.

Yes and also glad I have my own router with it's own security system so that the Modem the public might be connecting to can't possibly make a connection to the local network without a proper router priv.
One of the reasons why I always suggest people do not use the ISP router as their own and insist the ISP put it into Bridge mode so the only way anyone can possibly get a local IP is by going through my routers own security.

I have the xfinitywifi disabled on mine and changed a majority of the default settings.

Anything related to...
AP Isolation (should be off)
Multicast (needs to allow multicast, but the on/off state depends on the exact setting)
IGMP (depends on the exact setting)
?

I'm not having any issues... but I did find this:
I couldnt really find anything regarding AP Isolation, But I know by default ICMP and Multicast are blocked. Theses need unchecked.
Gateway>Firewall>Custom Security
Uncheck 'Block ICMP' and Uncheck 'Block Multicast'
Edit: Setting the firewall to Low Security will also enable ICMP and Multicast
dpalmer76, is your comcast biz router a DPC3939? Its 'Incompatible'...

Comcast routers have a user accessible admin panel. They have the info for logging in on their site.

I'm actually shocked! LOL

Thank Thad
Here's how I got mine Chromecast to work after getting the "cannot communicate with Chromecast" error on the final step of setup:
Called Thad with Xfinity Customer Service, and he found a fix. Tell your support agent to
Factory reset the modem
Set security of the modem to WPA2AES
Enable UPnP and set the time to 30
Set hops (scale of 1 to 5) to 5
Enable Zero config
After resetting your Chromecast and going through setup, it should begin to work.

Chromecast
So you don't need to even call comcast for this and it'll save you time because they really just don't know.
Go to 10.1.10.1/ on your browser. The User is : Cusadmin and the pass word is: Highspeed. It may change on your region but comcast will give you that info.
On the left menu Click advanced, then under device discovery on the left you will find all the settings you need.
as twill said UPnP enabled. Advertisement period set to 30. Time to live/ hops 5 and zero config enabled

I can NOT get it to work with Verizon FIOS Actiontec router

I plugged in the Chromecast and put in all the information and waited while it tried to connect to my Actiontec router. (Verizon FIOS) I waited, and waited and waited. After about 10 minutes it goes back to the beginning. The help button says I need to turn off the Access Point Isolation on my router. Unfortunately there's no such setting. I'm not happy because I have 3 more of these coming tomorrow and if I can't connect to my network I'm shot. Panic starts to set in.
Luckily, I have a cheap $30 Fry's wifi router on my network. I switched the Chromecast to the Fry's router and, bam, it connected immediately.
So, if your cable company's router doesn't work, just go out and buy a cheapo wifi router and you'll be fine.
The joy that is reading Verizon FiOS/Actiontec entrails
Deep voodoo Actiontec solution: You need to disable the IGMP Proxy.
The exact location of this checkbox changes between Actiontec revs but a good start is "Advanced/Routing/Routing Protocols/Internet Group Management Protocol (IGMP)."
Once this is off network devices typically can discover & connect to eachother.
Another strategy is, on the latest revs, enabling IPv6 (no, after years of promises Verizon still hasn't rolled IPv6 out yet, but at least the latest routers might be ready.) Anyhow, this is often reported to resolve local connectivity issues.
Just for reference, I have the newest Fios Actiontec router, and had no problems. Just so everyone with that router doesn't think they'll necessarily need to do this.

Good point. Mine's about 6 years old, maybe I should get them to replace it.
I had the same problem. Turned off NAT, connected, then turned NAT on
Guess this is reason #153 why I'm glad I have a Linksys router piggy-backed off of the crappy FIOS unit for the majority of my networking needs
A tip if upgrading to a newer Actiontec router: The settings backup files are *not* compatible between versions.
I upgraded to the latest router version six months ago; I'd done a lot of customizing (assigning addresses, ports, etc) and assumed it'd be an easy switch. I ended up having to temporarily return my newer router to get back my old, screenshot many pages of settings, return the old for new, then re-enter settings. A hassle, but it does run better now.
Assuming the local depot/storefront has 'em in stock it's a few minutes to swap out for a newer or newest revision.
Coincidentally I had a visit a week later to replace a burnt-out-again ONT & the tech reported he'd changed things around a bit in it for even better service. I've no idea what that involved but if it's been a long time you might want to look into a service call.

Some Help
I also picked up a Chromecast yesterday and am on Verizon Fios with the new Actiontec MI424WR router. I cannot get my Chromecast to connect. Sometimes I see it on the network, but it will not connect. Verizon, Actiontec, and so far Google have not been able to help me. I tried the tricks in this posting, but no luck.
I have a Buffalo Air Station wireless router, but have not had success operating this in conjunction with the Fios service (I have tried to bridge it, and run it just off ActionTec). Can someone help? I am okay at digging into this stuff, but you guys know so much more than me!
HELP!
success
The instructions below worked for me. Found it in an Apple Forum out of all places.
log in to your router(192.168.1.1), go to Wireless Settings then Advanced Security Settings. At the bottom of the screen, click "Other Advanced Wireless Options". On the next screen change Network from "Network (Home/Office)" to "Broadband". Click Apply
Just curious but it could be that you have multicasting disabled on the router.
It could also be that the router does not support multicasting in general, but this is a feature that allows devices to discover each other on a private network.

I am having the same issue with DIR 655 router. Tried all the suggestion in this thread. But still no luck. Anyone having similar problem with DIR 655?
I'm having a similar problem. I've got a Linksys router that is happily supplying WiFi to my laptop, mobile phone, Kindle Fire, and XBox, but I can't get Chromecast to work properly. I get partially into the setup and then get the following message -- "Chromecast connected to [Name of Network], but can't connect to the internet." I've fiddled with countless settings to no avail. AP/Isolation mode is disabled, I've only got 2.4 GHz bands, the router is 20 ft away, etc. All the suggestions the Google Help guy gave me have had zero effect, so I thought I'd post here to see if anyone else ran into this error message and had a solution.

OK! finally found the issue. If your wifi password is too long(auto generated for WPA2) then chromecast cannot handle it. Reducing the length of router password fixed it. I reduced it to ~20 characters. Have not tested the pw length limit of cast.

My password is only 9 characters, and I have tried everything else suggested here. Anyone else have any ideas on how to get it to work?
I'm also having a similar issue with my DIR-601. I am able to detect my Chromecast but after the screen that asks for the WiFi info /renaming the Chromecast, I get an error stating that we were unable to find Chromecast on your network. I have checked that UPnP and have Enable IPv4 Multicast Streams selected (tried both ways.) I don't have any special firewall rules or anything like that. My pass is only 8 characters.
Wish Google had better support for this, all they have is a little questionnaire on their support page.If anyone finds a solution, please share. Thanks
Out of curiosity where is the enable multicast option at? I didn't see one.

None of the suggestions in this thread worked for me. I have the Actiontec Gen 3, rev I router (MI424WR-GEN3I), with firmware v. 40.20.7.
Apparently, the UPnP page is hidden, but can be accessed after logging in to the router using: 192.168.1.1/index.cgi?active_page=900. Changing the settings on this page didn't work either.
After a quick Google, I found an IGMP hidden page at 192.168.1.1/index.cgi?active_page=6059. I looked at these settings yet.
Calling Verizon's Expert Care, I was told that they don't support UPnP, since they only provide access to the Internet.
Fix found ... at least for me

I had the same issues as everyone else at both my office and my house. At home, I changed the IGMP settings, the UPnP settings, the security settings, etc. I finally figured out a way to make it work by simply trying to complete the setup from my laptop instead of my Droid 4. It worked on the first try at my house, and now all of my phones, tablets and computers can cast to the big tv. I immediately brought my laptop to the office and changed the IGMP setting -- and it immediately worked after that.
So maybe a solution is to try setting it up from your computer instead of your phone/tablet? It worked for me twice that way!

Chromecast problem "but cant access the internet" on Belkin Router

Hi everyone,
I have a Beklin Share N300 router and trying to set up my chromecast on this network.
Everything works fine, i mean the set up process; chromecast can see the network, can connect the network without any problem but get this message on the screen:
ChromecastXXX connected to yournetwork, but cant access the internet.
Has anyone faced this problem before?
I appreciate for your comments

Im been having the same problem since yesterday morning. Ive been in contact with Google and they escalted my case but i havent heard back from them about it.
I had the same problem with my E4200v2 router. I just kept trying and trying from the chromecast app on my Samsung Galaxy S4 and after an hour it finally setup. Have patience and keep trying everything. Reference your router's manual for additional information you might need. Good luck!

did you try putting the CC in the DMZ?
I don't have the CC yet, so I don't know if it needs any ports open in your firewall. Is there any way to manually enter a private IP or DNS info?
From what you're describing, the Chromecast isn't getting the DNS information.

DMZ could be the solution. Try disabling AP isolation under your router's setup UI.

The AP (access point) he probably doesn't have setup anyway since that's more for bridging.
I just don't know if CC needs any ports forwarded. He may want to see what IP is being assigned to his CC and then check the firewall logs to see if any traffic is being blocked by it. The DMZ on his router should place the CC in front of the router and thus let all traffic to and from it, which should, in theory, fix the DNS problem.
It maybe to worth a shot to port foward port 53, which is usually used for DNS. I don't remember if it was UDP or TCP or both. And sometimes you still need to port forward even when using the DMZ. It's lame, but router's just act funny sometimes.
====================
it just dawned on me, it might be that CC is getting it's internet access from the device that's getting the content. So, you may need to enable internet sharing on your PC. Although, I don't think this is the case.
I also was getting the "connected to wireless, but can't access the internet" What I determined is that the ChromeCast is NOT using the DNS servers provided by my DHCP server, it was trying to communicate to a different DNS (likely Google's own).
In my case, I had a firewall in place that prevented access to any DNS other than what I was providing in DHCP. Once I opened the restriction and allowed all DNS traffic, chromecast immediately connected.
Hope this helps someone else.

Interesting. In my case, it was the opposite. I had my laptop configured to use Google's DNS servers and I kept on getting the same "connected to wireless, but can't access the internet" message. I reset the DNS servers on my laptop and Chromecast immediately connected to the Internet.
anyone know which port/s does chromecast use
DMZ worked for me but i dont like putting devices on DMZ. Sounds like this is just a port forwarding issue and putting it on DMZ is an overkill.
Anyone knows which port/s does chromecast use???
I also have the Belkin N300 and was having the same trouble. What i did was a factory reset on my router and a firmware update in the router settings and now everything seems to be working fine as of now.
AP Isolation
Switching off AP Isolation fixed the issue for me. I had the same issue before I did this.

I tried this too, even porting, but no luck..
tried every single suggestion but cant figure out what is wrong.
What i understand from the replies; it needs some specific DNS. But when i change my DNS on my routers setting page different than provided my ISP, router itself doesnt connect to internet.
DMZ, MAC filtering, disabling Firewall, disabling AP, none of them work so far; with numerous combination of those...
I believe it shouldnt be that hard.. ?
Update: Placing it in DMZ took a couple of retries but have fixed the issue now.
Similar problem. Worked on the first setup. Then after two day a get "can't connect to internet" message. Tried factory resetting and putting in the DMZ. Nothing helps. Anyone?

I don't really have more suggestions. From what I know, the CC doesn't need any special DNS information because really all the CC is just a media player (although not exactly correct). When you cast something to it, the device (mobile device or PC) you're sending it a URL, which it then opens and can play. This is why it needs an internet connection. Tab casting is a little different. Thus, if it'll play on your mobile device or PC, you can play it on the CC (assuming the content is CC compatible). If there is not internet to the CC, then the DNS and ISP information is not being forwarded to the CC or it's not connecting to them; this assumes it's getting an private IP from the router and not being denied because of MAC filtering or something.
Over here I've got another problem. My current ISP forces me to use their DNS. Since the Chromecast has its own fixed Google DNS (8.8.8.8 & 8.8.4.4), the Chromecast is not allowed to connect to the internet.

Same here, I'm on a studentnet that uses a PPTP connection with their own DNS, so if I change the DNS I won''t have an internet connection, permanent. Not sure how to fix that.

I had the same issue with the original firmware (12072).
After leaving it connected a few days it eventually stayed connected long enough to download an update.
After restarting it, it applied the update.
On firmware 13300 it complains when it initially boots, then after about a minute or two it connects successfully.
So...
If you're rooted, use FlashCast to update to PwnedCast 1.0 (based on 13300)
If you're not root-capable or have no plans to root, set it up and leave it at the "but can't connect to the Internet" for a few days (just leave it powered by the power adapter), then power-cycle it, hopefully you will see it updating.

Chromecast will not connect to my TELUS ROUTER

Good advice.
Remember that the WiFi bands (channels) are not exactly the same between countries. So if you're in a non-US country and your router happens to choose a channel that is not available in the US, Chromecast may not detect your wireless AP.
But Telus is Canadian, and Canada has the same WiFi channels as the U.S. (Canada and the U.S. necessarily share identical radio spectrum allocation).

Didn't know that. Thanks! Still applies to other countries though. I think Channel 13 is one of the channels that applies to Europe but not US. I should put it in the FAQ...
EDIT: Seems there's far less exclusion than I thought... but added a note in the FAQ just in case.

So I can get through the setup phase up until the Chromecast tries to connect to my wifi network. I get a message saying it couldn't connect, and when I click the link in the message it brings me to a page that mentions AP filtering, UPNP enabling and .NET 3.5. I checked and UPNP is enabled, and I can't find an option for AP filtering (I have the Actiontech V1000h). I am using a Macbook pro.

In some cases you have to go through a couple of times. I just reset my Chromecast to test a few things and had to go through the setup twice before it connected to my WiFi.
Chromecast in Canada, on Telus
A friend lent me his chromecast. He uses an iphone and Shaw cable. I use a Nexus 4, and have Telus as my internet provider.
It was a bear trying to get chromecast to work. Tried 5 separate days. Got it to work and i could watch netflix/youtube on it about 3 times and played with it for a couple of hours each. That's the success.
The fail is that I had to trouble shoot more then 4+ hours to get it to work those 3 times. Reboot the chromecast. Reboot the router. Reboot my Nexus 4. Try my wife's Nexus 4. Try the Nexus 7 tablet. It was a horrible experience. I got the AP recommendation like the earlier post in this thread. I tried that. Tried calling telus and signed into my router to check that those settings were correct. As far as I understand it's a gateway 11n wireless router.
So my conclusion is change my internet provider to Shaw unless someone has a smart solution to this problem. The router says it's a 50ghz signal? So it isn't the 2.4vs 5.0 ghz signal problem that I've googled and read about.
Please provide some brains to my situation. I've used all of mine up.

So I took the plunge and bought one. Maybe it'd be different than my friends. Looks like this is a me problem. The chromecast still doesn't work. I thought it might be the tv that it's plugged into? Maybe shielding the chromecast from the wifi? I don't know. Will trouble shoot with a different tv or a long hdmi cable that will get the chromecast out from behind the tv. Maybe that'll help.

TVs are great at blocking/scrambling radio signals.
Use the included HDMI extender. If that doesn't help (enough), get an HDMI extension and move Chromecast away from the TV. One of mine is on a 10-foot HDMI extension. The other is connected upstream of a another device that connects to my TV, so both of my Chromecasts are at least a foot away from its associated TV.

It could be a few things not related to the router directly but related in how the Router connects to your ISP.
So a couple of questions...
What kind of service is your ISP? (DSL, CABLE, OTHER)
What Public IP does your router report? (Usually found on the status page that shows connection data) If it starts off 192.168 then your Modem is doing a double nat translation and you need to call your ISP and tell them you want the Modem to be put into gateway mode and just pass a public IP to your router.
Does the CCast actually connect to the Router but not work or will it not connect at all period? If it doesn't connect at all it is possible you need to change the Security method used to WPA or WEP. To test shut off security alltogether and try to connect the CCast. If there is currently NO security try putting WPA on and trying again (but it should work on an open AP)

(Usually found on the status page that shows connection data) If it starts off 192.168 then your Modem is doing a double nat translation and you need to call your ISP and tell them you want the Modem to be put into gateway mode and just pass a public IP to your router.
Does the CCast actually connect to the Router but not work or will it not connect at all period? If it doesn't connect at all it is possible you need to change the Security method used to WPA or WEP. To test shut off security alltogether and try to connect the CCast. If there is currently NO security try putting WPA on and trying again (but it should work on an open AP)

Service is Telus DSL.
Solution: I changed the security settings. It still tries to stop the CCast from talking to my phone once in a while, but I just log into my router and log into the firewall settings. The firewall settings are "high, medium, low, NAT". It started working once I started turning it off of NAT and onto Medium or High.
I don't know why this is the solution, but it is a solution. I suspect that either Telus will fix the prolbem for everyone else or this thread will become popular. Now CCast is coming to Canada. So either Telus fixes it or there'll be a lot of searching leading to this post.
As a reminder, a friend of mine on telus never toughed his firewall settings and never had a problem with using his CCast. Go figure.

Well if the Telus was set to NAT perhaps Double Nat Translation was the issue.
DO you have another router connected to your modem or is this one of those all in one Hybrids supplied by the ISP?

I have a friend that is struggling with this as well. While setting up the WiFi connection between the chromecast and the router (the Actiontec V1000H - which is a modem/router combo if that helps). The chromecast will see the WiFi, but it seems to time out while trying to connect to the router.
I did find a comment on a blog somewhere (sorry, I forget where) that suggests unchecking the "IGMP snooping enabled" option in the router (Advanced Settings>IGMP Setting). Once this was done, the chromecast connected to the WiFi without any issues and we were able to stream it without any issues.
However after going out for dinner we had major issues trying to connect to the WiFi on our phones and his laptop (laptop would try to connect to the WiFi but continually fail). It seems like this is a temporary fix at best.
The only permanent solution I can think of at the moment is to go buy a new router that is listed as having no issues on the chromecast compatibility list... Which kind of defeats the whole purpose of having the chromecast as an economic way to stream content to your big screen.
Buy a better router
I don't see why IGMP should have any affect on being able to login and connect.
I Can see it being a problem with streaming but not connection.
IS this an ISP provided Modem/Router? How many devices are connecting wirelessly?
Check settings for IGMP Proxy, Try changing that setting whatever it is but it should probably be disabled (Still don't think this would affect connection but it's worth checking)
Check if UPnP Is enabled (again not really connection related but it does need to be enabled for CCast)
I personally prefer to use a two device setup with separate Modem (in Bridge Mode) and Router....This way the Modem protects the router from the outside world and even if the Modem goes bad the Network still functions properly.
And I pretty much stay away from anything that isn't a Linksys or Netgear product as far as Routers are concerned.
There are a bunch of Actiontec models that are listed as incompatible with CCast on the google site so it's obvious that something about their firmware is not CCast friendly.
So the the previous poster may actually have made a good suggestion in the long run! LOL
I'm using the telus actiontech router with chromcast with no issues....
its a pretty crappy router though and it seems telus disabled the ability for bridge mode in the latest firmware... has anyone found a solution to this so i can buy a better router?

As long as double NAT doesn't cause you problems, you can
Assign the new router's WAN port to an address in the ISP router's LAN range
Set the new router's gateway to the ISP router's LAN address
Connect the two routers LAN port to LAN port
Have all your wired and wireless clients connect to the new router.

802.1x

Why Google you no like college students?
Hmmm this probably raises a good point, it's a bit hard to implement something like 802.1x though on a streamer device (where authentication is required per login of network prior to you having the ability to control the device).
I don't see this coming for awhile to be honest unless someone manages to hack it in - I just can't see Google releasing the ability to cache 802.1x network credential sets unfortunately due to the security implications.
Friend of mine had to buy his own router to plug in to the colleges ethernet ports in the dorm. Solved a variety of issues they were having.

Beyond the lack of keyboard/interface, large networks in general fear multicast and UPnP because they have potential to easily clog the network.
Also remember that Chromecast in its current state has little security - it's designed for use within a trusted environment.
You probably don't want to be in the middle of Twilight with your girlfriend and suddenly your Chromecast switches over to SpongeBob SquarePants because someone else in the dorm decided BobsChromecast obviously wants to show SpongeBob...
Having your own router and local network will isolate your Chromecast to just your little piece of the campus network, though double-NAT might be an issue, and you should check with campus policy on use of personal WiFi router/AP hardware.
I've got a similar problem. I use a studentnet, were I can either plug in directly into the wall and log in once every day or setup a router with a PPTP-connection to automatically log into the student-network. I've got the latter set up and it works like a charm.
Thankfully I had a rootable CC so I could set it to use my ISP's DNS but I would love if it if I were able to use a different DNS (aka Unlocator/Unblock) to enjoy the US-version of Netflix, but every time I change the DNS-servers my internetconnection dies.
Is there any way to actually do fix my problem? I know this is more of a network-question than a CC-one, but CC is included in the problem
I use a Netgear WNR3500LV2 as my router.

First question is whether you can use a different DNS at all (or whether your ISP is blocking somehow).
Try doing a DNS lookup from another server on your phone/tablet via Ping & DNS or another app that lets you do that.
If that's successful, then it might work - go to the Eureka-ROM web panel at http://Chromecast_IP_addresss/ and turn off DHCP-supplied DNS, Apply, then select another DNS.
You will also need to force your phone/tablet to use the same DNS - otherwise your phone/tablet may be making requests from Mars, while Chromecast tries to retrieve stuff from Venus.

Can't connect Chromecast to Netflix

I took delivery if a Chromecast today and the setup is a breeze. As I'm in Europe I have changed some settings in order to access the American version of Netflix because if the extended selection of films and series. It runs fine on my Galaxy Note 8, iMac, and Xperia Z1. But it can't run on my TV. Every time I try to cast a film on it I get this error: "Whoops, something went wrong...Device Messaging Error. There was an unrecoverable error on your computer. Please reload the page to resume controlling your device."
I have done some searches and found various possible solutions, but none worked. This is what I've tried:
- Signed out of all devices in Netflix.
- Reset the Chromecast.
- Disabled WWM on the router.
I doubt it's an issue with Netflix as it works fine on all devices except on the TV. Sometimes I do see there is an error on my iMac saying that Microsoft Silverlight has crashed but that doesn't seem to affect anything. Is there anything else I could do to troubleshoot?

Please tell us...
What make/model router do you have?
Can you describe how you "changed some settings" to access US Netflix?
Do YouTube and other services work?
If you use your normal DNS settings and access your local Netflix, does it work okay?
Chromecast is its own device and does its own DNS lookups and Internet requests after receiving the "go play this video" request, so if you're redirecting DNS on specific IPs/devices (rather than everything on your network), then you need to be sure the Chromecast IP/device is being redirected.
Otherwise your phone/tablet/computer is in Mens and Chromecast is in the Ladies and...
Phone/tablet/computer: "Excuse me, could you get my phone next to the urinal?"
Chromecast: "What's a urinal??"

Thanks for your reply.
The router is a Cisco EPC3925.
I used the instructions from the Unblock-us website. Changed the DNS settings to 208.122.23.23 and 208.122.23.22 as instructed. But I also changed the DNS settings to that on the Cisco router - otherwise the US material would not show on my tablet and phone (only on the iMac).
YouTube and Plex work just fine when casting material to the TV.
When using the normal DNS settings from the local Netflix it works fine.

Thanks for the info.
Seems like your core problem is that by default Chromecast uses the Google DNS servers regardless of what DHCP provides, so even though you've set your router so all its DHCP clients are being told to use the Unblock-us DNS, Chromecast still isn't. So all your devices are in the Mens, with the exception of Chromecast, which still goes to the Ladies, even though you tell it go to the Mens, thus it responds with "What's a urinal??" when you reference things in the Mens (US stuff).
Chromecast will fall back to using the DHCP-supplied DNS server(s) only if it doesn't get a response from Google's DNS.
Normally the ways around this would be to:
Route Google DNS requests to a bogus/non-existent gateway
Block Google DNS requests entirely
so Chromecast does not get a response from Google's DNS. Which one works depends on how your router handles the blocking/forwarding. You want a timeout or destination unreachable, rather than an outright refusal.
But... I looked in the manual for your router (seems to be a VoIP+modem+router combo) and unfortunately I couldn't find any way to add a static route, nor did I find a way to block or forward requests specifically for Google DNS.
So unless the ability to add static routes or the ability to block port requests for specific WAN destinations has been added, you may be a bit stuck. Definitely check through your router's config to see though, often times the manual lags far behind the current feature set.
However, if you don't have the necessary options in your router, that leaves you with these possibilities:
Add a router that can provide blocking or redirection via one of
static routes
IP-specific port-blocking
iptables rules
to provide network to Chromecast and devices controlling Chromecast (they need to be on the same subnet).
VPN - which is beyond my area of expertise for this usage.
Get a rooted Chromecast so you can use Eureka-ROM to enable use of DHCP-supplied DNS rather than Google DNS
If you go with option (a), you will have double-NAT, which can be problematic.
You would connect the new (filtering) router's WAN side to your existing router's LAN site. You cannot connect the two routers LAN-LAN as the new router will only filter/redirect traffic when it does the IP translation from LAN to WAN.
If your existing router has a Bridge option for its LAN connection, that would avoid double-NAT (bridge will connect the WAN side to LAN side transparently and disable all router NAT and filtering), but it's more likely that you would get a Static Route option before you get a bridge option.
Anyway, contemplate a bit, first check if there's Static Routes in your router's config. Sorry this has been such a verbose post.

I don't know much about modems/routers so would be a bit wary of setting up a new router. I checked in the setting on the modem/router provided by my ISP and there is an option to add static ip. Would that be a way to block Google's DNS?

Unfortunately not - and don't change that - you'll lose Internet connection.
While you're there, though, can tell me what options you have in the Working Mode dropdown where it currently says Router Mode?
DON'T change it though - that's likely to break your Internet connection too.

Cool. If you decide to get another router, you should be able to switch that dropdown to Bridge Only and connect your existing router's LAN port to the new router's WAN/Internet port, and it should avoid double-NAT-ing.
Essentially your existing router would only be used as a modem (and VoIP, if you're using VoIP), and you'd disable old router's WiFi and do all your DHCP, WiFi, etc on your new router.
As a rule I try (best I can) to avoid Dual Purpose networking devices as I have found they do neither task very good....
Unfortunately ISPs are moving towards these all in one boxes (Modem/Router/WiFi) and it Wreaks havoc on those who have their own networking gear....
Whats worse is they are locking the configs of these devices so that you can't change them easily to get it to do what you want.

You can also try this simple test without the router to see if it works....
Connect your computer directly to the Modem/Router...
Set the Router to Bridge Only mode and if your PC gets an outside (Public) IP Address then you know it will work with an external Router.
The only issue you might face is sometimes if the ISP provided the Modem they program it not to accept that change without it coming from their side.
I connected a new router (ASUS RT-N56U) to the existing router/modem. The existing was set to Bridge Mode with DHCP off and it can connect to the internet but not cast any show (local or US) to the TV. Not sure what details are needed for you to help me getting it to work. I can cast local Netflix onto my phone and tablet. YouTube videos can cast to TV.

Not totally up on the settings screens for your new router but check to see what IP Address it has under the Internet settings.
Every Router has two IP Addresses, one local (192.168.x.x) and one Public (should be provided by the Modem in bridge mode),
If both are local IPs then your double NATing which will easily break Netflix. If one is a Public IP then check other settings in the new router most notably UPnP and Multicast.
Also ( sorry dumb question follows) but you did make sure to set up the CCast to connect to the NEW router not the old one?

There are two IP addresses: 192.168.1.2, 192.168.1.254, first one local and the other public. I can't locate UPnP and Multicast in the router.

As I suspected...Your Double NATing is the problem....Your new Router is not actually breaching the Modem to the Internet.
This modem also has WiFi built in I bet....
The DHCP you shut off probably doesn't apply to anything directly plugged into the Modem. Just the WiFi.
You need to look for a setting that gives you the option of passing a local/internal (192.168.x.x) IP or Outside IP and set it to pass an Outside IP. (this is on the Modem BTW)
If the Router reports any IP that starts off 192.168 for Public then you are not set up correctly.
If you see the option to change from local IP to Outside IP but it is greyed out then your ISP locked it out and they must make the changes on their end.
Call and tell them your Modem is in Bridge mode but doing double NAT translation and you can't breach the Modem with your router.

As @Asphyx said, there's double-NAT going on. This may be a problem, but the core problem at the moment is that new router's WAN and LAN are using the same subnet.
I recommend...
Turn off the WiFi on your old router, if you can.
Look for the stuff Asphyx mentioned.
If you get stuck, call your ISP
Ask them to enable Bridge mode and explain that you're looking for more robust routing and firewall features
Ask if there's a firmware update for your existing modem/router combo to provide this, if there is a different ISP-provided modem/router you can use that has better features, or if they can provide/recommend a modem-only device (if they don't/can't enable Bridge mode)
Ideally, you want to see is your new router getting a WAN address that is not 192.168.x.x
If you reach that point, you're done.
If not, you at least want your new router getting a WAN address that is in a different subnet from its local network.
On your new router, change the Local address to 192.168.2.2
That will switch things on the new router to the 192.168.2.x subnet. Now the new router and old router will be on different subnets.
Make sure any client devices (wired or wireless) that have static IPs set are changed to use IP 192.168.2.something and gateway 192.168.2.2
My network is double-NAT and I have not had issues with Chromecast, streaming, VPN, or anything else, but you definitely should avoid double-NAT whenever possible.
