How to setup chormecast in dlink 2750 router - Google Chromecast

Please help me to set up chormecast in dlink 2750 u router
i can connect to router but it show not connect to internet
thanks in advance

What are the first 4 digits of your serial number? Just curious what firmware build you might be on. If you're on 12072 you might want to get root while you still can!
Looks like your router is D-Link 2750U?
Page 36 lists a Wireless Multicast Forwarding (WMF) option - you might have to enable that for Chromecast discovery to work, but first we need to get Internet...
Page 58 lists a LAN to LAN (Intra LAN) Multicast Enable option - again, you might have to enable that for Chromecast discovery to work, but first we need to get Internet...
Page 63 - Enable IGMP Snooping - you may need to toggle this setting.
Other than those, I dont' really see anything that would specifically block Internet access from Chromecast... Make sure you can ping 8.8.8.8 and 8.8.4.4 from the 2.4 GHz wireless network using another device if you can.

Sorry for the late reply
it work automatically
i just have o brought a wifi extender as my router far away from my tv

problem connecting to the house internet

Hi this is my first time on a site and I just wonder if anybody can solve my problem!
I,ve read a few posts and set my xda llI so that in connections my network card connects to work!Also have done all the rest and set it to internet just in case as well
My Isp in connections window is on the advanced tab and select networks on the network Management is set to My Isp.
my Wirles Lan Manager is status connected to network
My ssid is the one that all the house computors are set to,my mode is Infratructure and Tx is Auto.My channel is 6
my bssid is 00-18-2D etc etc.
My Mac is 00-09- etc ,etc.
My IP.169.254.168.73
signal quality is good
I,ve been onto the 192.168.0.1 website and added the mac address of the xda lli but when I try to get the internet on the xdalli to connect it justs says default page. I cannot seem to connect. is this normal or do I have to go through O2 to pay for another internet connection besides my home address one.Have I missed something out!Help would be greatly appreciated! thanks

Hi,
Your IP of 169.x.x.x means that you are trying to use DHCP to get an ip address but haven't been supplied one by your router..
The ip addres of your router is 192.168.0.1, so it may be sensible to setup your router to allow a dynamic address range of 192.168.0.100 to 192.168.0.110 (say) - when anyone tries to connect using a dynamic address (using dhcp), they'll be given an address in this range.
So, initially check if DHCP is enabled.
Do you have a laptop that connects using a dynamic ip address (ie not static - ie not implicitly defined) - if so then DHCP _is_ already working and there's another problem.
If this is the case, I'd initially disable any kind of mac-filtering or security until you get a simple connection going..
Sorry, if this isn't too clear - I'm tired - what router are you using?
Kev
First hand it can depend on your router
I have had problems connecting with Virgin broadband routers for instance.
Have you tried connecting elsewhere?
Also what type of security do you have on your router?
One more thing to try
Check under the "Network Cards" settings when disconnected and select "the internet" from the drop down menu.
Hope this helps
clearing the way so that I understand correctly!

My router is a netgear dg834GT.I,ve looked at the range and the range for 192.168.0.1 actually goes from 192.168.0.2 upto 192.168.0.254 so the range should be there. how would I know if the router is DHCP, is there a way of seeing this? The filter would be set up where for the mac address?Is there a way of changing the isp on the phone so that its range is within the 192.168.0.1 range?the only security that I have is the routers own and the avg antivirus.would disabling the avg help!

If you haven't set up mac filtering, then it won't be a problem.. if you have, then there should be an option to disable/remove any you've input - build security up from a working setup.
Have you (can you borrow) a laptop that you can setup wireless with a dynamic ip address and check that connects; if that's okay then the router is setup correctly.
So I the Alpine comes up with "connected to network" but the ip address is 169.x.x.x ..
This means that the Alpine has not been allocated a usable ip-address by the router for some reason and you'll get nowhere until this happens.
Your other PCs.. are they set to dynamic ip addresses - I guess so as you have no room for static addresses. You should probably check they're all dynamic as if (say) you've allocated a static ip address of 192.168.0.2 to one of them and then DHCP tries auto-allocating addresses, I guess there could be a conflict (don't know how clever dhcp is). Usually I would set the DHCP range to 192.168.0.100 -> 192.168.0.200 (allowing 100 different dynamic addresses).
Have you checked that authentication is set top 'Open' and Data Encryption 'Disabled' on the Alpine; and ensure you've disabled (temporarily) all router security..?

Thanks kev for replying.
I have a hard wired lead to the router for one computor and 3 laptops connected by wifi and another computor connected by wifi.
the range or should I say the ip addresses are 192.168.0.3,192.168.0.4
upto 192.168.07.I,m at work at the moment but as soon as I get home tonight I'll set the wep key to disabled is there any other thing on the router that I need to do?
Can't think of anything else...
But at least you know DHCP is working if the other PCs are getting ip addresses okay.
And you know the wireless is working...
So it does look likely that it will be something to do with WEP/WPA encryption... (I guess you've got it setup at home), hence why the router isn't allocating you an ip-address.
If you can't get it going, it may be worthwhile doing some sceenshots of the router configuration pages (or config files)...
What I can tell you is that what you are doing looks correct and you have everything setup so you can go on the internet whilst at home using the Alpine. Mine uses the router whilst at home and GPRS whilst out.

The dg834GT is pretty much the one that Virgin use, like I said in my earlier post.
I have found these particular routers to be a problem (sometimes) with my Alpine.
You should try to update the firmware.

Well Done Kev!
It was the "open"on the phone and putting "open" on the router.I had to intiallely disable the wep key.then when I got connected,I reactivated the WEP key and I could not connect.So on the phone I unticked the automatically connect to my name of my router name and reput in my encryption key again and I was in and On line.Thanks to both of you(Kevcal and Voxshots) for helping me.Definately could not have done it without you Pair.I like the idea of using the screenshots so I,ll post a screenshot of all the settings on the phone and computor so that anybody else will be able to resolve there problems with all credits going to you people on the bottom!
Very happy to have helped and glad you sorted it out

Chromecast connected to wifi but cannot access internet

Hi All
Got my chromecast to connect to the router, it even says "ready to cast".
However, on the TV screen it says: Chromecast connected to wifi but cannot access internet.
My router is a TP-LINK N600 Wireless Dual Band Gigabit Router, Model No. TL-WDR3600
Firmware Version: 3.13.31 Build 130320 Rel.55761n
Hardware Version: WDR3600 v1 00000000
For Wifi the settings are:
Wireless 2.4GHz
Wireless Radio: Enable
Name (SSID): Internet5A_2.4GHz
Mode: 11bgn mixed
Channel: Auto (Current channel 1)
Channel Width: Automatic
WDS Status: Disable
I connect to internet using PPPoE
Router is right behind the TV, where the chromecast is.
AP Isolation is disabled
Any kind of help is greatly appreciated!
I have already gone through troubleshooting, restarting router / chormecast, factory defaults for router / chromecast..etc
Called Google, they had me to it all over again, still the same thing.

Well first question...Can you stream Media to it? If your using aVia you shouldn't need internet.
Check Router settings make sure you don't have something like Mac Filtering on (although I would think it would not connect at all if that was the case)
Also check to see if you have Internet Access limited for any Mac Addresses.
Make sure UPnP is enabled on the router.
I looked at the router compat chart and all of the TP-Link routers appear to be compatible so if it is therouter it will be some setting you changed from the default.
Also check to see if there is a firmware upgrade for your router.
I should point out though that Google is notorious for lying about Internet access and in many cases use a successful connect to Google Services as the indicator. If thats the case here then it may very well have Internet access but couldn't connect to Google!
We know Google thinks it is the internet but it isn't the entire internet! LOL
Almost forgot...If your router connect via PPPOE make sure to set it to not expire and stay always on.
If you have it set to connect when needed then the CCast may get a No Net access response while the router is connecting.
Can't stream media to it. Tried it with Avia, (chromecast inapp purchased).
Mac filtering not enabled
UPnP is enabled
There is a firmware update that I will try later today and reply with the results.
Thanks for your support!

If the firmware update doesn't fix things, look for additional options related to Multicast, IPv6 and IGMP

Definitely check your PPPOE Settings to make sure it is always on...
If not then you aren't always connected to the Internet and CCast may only check status on initial connection.
Inability to cast at all says to me that something else in your router config is amiss but It's possible that since it can't get to the Net that it can't retrieve the Whitelist which would prevent casting from anything.
Tried all of the above. Still no joy. Updated firmware to latest, etc..
IGMP Proxy: Disabled
This text is just under the IGMP Proxy setting, in RED:
IGMP(Internet Group Management Protocol) works for IPTV multicast stream.
The device supports both IGMP proxy with enabled/disabled option and IGMP snooping.
Enable AP Isolation - Unchecked
IPv6 - disabled
Thinking of giving up on this..
Can you successfully ping Google DNS at 8.8.8.8 from another device connected wirelessly to the same router?

Does not show it as in... the router still shows the option as disabled, or something else?
Pretty much all the option types that Google mentions for the various routers in their router known issues page, it's worth trying on and off, if your router supports it, and only if you are having trouble. It's more combinations, but worth a shot.
Otherwise, if it ain't broke, don't fix it.
Thank you all for your help!
I disabled parental control (on ISP side), and it worked!
Sorry for all the trouble!
Thanks for your help. For me it was pppoe set to Connect auto, changed to manual 0 - never disconnect works like a charm. (TP-LINK W9960)

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??"

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.

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.

Sounds too simple to be true. I do have an extra router so perhaps I'll test it out at some stage during the week. Thanks for your help so far!

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.
I made sure to set the Chromecast to the new network. The old one shows but it's not connected to the internet. It's in bridge mode.

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.

Impossible to Setup

I had 2 Chromecast working just fine for a long time,one in the main network and the other in the second network in a room that is too far from the main router.
Then one day i disabled UPNP for security concerns and soon after I realized chromecast needed it and enabled it again, however i was never able to set up it again
I tried using many phones like Galaxy S4, RAZR D3, iPhone 6, Windows 7 PC, I tried resetting the Chromecast to factory defaults many times without success, then I tried the other Chromecast and reset it to factory defaults and could not set up it either, so the problem is on my network.
My wi-fi settings right now:
11n only, it's 2.4GHz only
Channel Width automatic,
Channel is set to 11,
IGMP proxy disabled,
[WPA2-PSK-CCMP][ESS](from wi-fi analyzer app)AES with 54.000 seconds group key update period,
My password length is 13 with ! and () and numbers
WPS disabled
Mac filtering disabled,
Transmit power high,WMM enabled,
Short GI enabled,
AP isolation disabled,
beacon interval is 50,
RTS threshold is 2304,
fragmentation threshold 2346,
using a DHCP server,
UPNP enabled(again),
SPI firewall is enabled ALG all enabled but SIP ALG,
Forbid ping packet from LAN,
Ignore ping from WAN(tried without this too, so i don't think it is this),
Parental control is disabled,
My router uses google dns by default.
I don't use any VPN
My router is a TP-LINK TL-WR941ND my firmware is up to date(3.15.9 for V5 hardware) it is connected to another modem that just run as a bridge and nat disabled if i remember right i don't think it is a problem it with it and the only options related to IGMP on it is IGMP proxy and chromecast support says it need IGMP enabled + IGMP proxy disabled so how i check out this?
I also tried moving the chromecast to a TV that is right next to my router, still get 'can't see the chromecast on your network',
I also tried to give the chromecast a permanent static ip, and port forward it(virtual servers on my router) 2-65535 UDP and 2-65535 TCP but still setup won't complete, i don't know what more i can do other than just trash this stupid chromecast and back to see all my series on laptop.
Sometimes i'm able to cast my tab from a little time after a failed setup but then soon it will say 'no chromecast found', my pc runs comodo firewall however it was not giving me any problem and i tried to setup it with it disabled.
For the god sake i just want to be able to watch my series again, anyone please help me! If you need any more info just ask it, i can run wireshark and send some prints if this can help too.
- edit
Tried today with an Ipad and has able to do the setup and got the screen ready to cast, however i see no ports open in UPNP, and the chromecast app on ipad said it was configured but was not possible to dectect it on my network, and also from time to time the screen would go back to 'connecting to your wi-fi' then go back to 'ready to cast' i was able to cast this table as i write this,will see if it will stay stable and come back.
On my Galaxy S4 GT-i9500 on my chromecast still says no chromecast found for some reason, but i'm able to cast from it, however i seems to get black tabs now when streaming to my chromecast which i don't like, verified the same for my Galaxy S5 , for my Ipad and for my Iphone 6, why????????? I can ping the chromecast too however i had 1% loss of packet on 200 pings in the same room as my router.
You mention you have a main network and a second network. Can you elaborate on how those are connected together?

The main network is the network of the house and the second network is the network of the backyard, but i'm trying to run the chromecast in the main network, and the second is currently off.
The main network is the tp-link router as access point to a TG862 ARRIS in brigde mode, with firewall and nat disabled.
I think my wi-fi settings are all ok right? So why the chromecast can't setup???
I'd try changing wifi channel to 1 or 6. I'm not a network expert but I'd try that.

Comcast Moden Connection

Cant get chromecast to connect to comcast modem DCP 3939 https://support.google.com/chromecast/answer/3438461 cant find these settings is there a fix or work around
My guess is that your have the modem/router from Comcast. I've learned that you need your own router as I spent weeks looks for a workaround for my in-laws.
Comcast blamed Google, which made me laugh when I connected the Chromecast on my own network and it worked. From my research, Comcast did an update to the modem/router that essentially caused the problem.
If anyone has found the solution, please share!

I have one of the comcast routers that was installed with my X1 box. Per the router info it's a Cisco Model DPC3939. It supports both 2.4 and 5 GHz.
Make sure you are connecting to the 2.4 GHz not the 5GHz (Chromecast help page says 5GHz is unsupported).
I tried rebooting router then chromecast, that didn't work.
I tried adding the mac address manually to the router and was still having trouble (router saw the chromecast as connected but during chromecast initializiation it couldn't connect to the newtork).
What finally fixed it for me was fiddling with the UPnP settings then rebooting the chromecast after. You can get to the UPnP settings by logging into the router, then:
Advanced > Device Discovery
These are the setting I have, that worked:
UPnP: Enable
Advertisement Period: 5 minutes (default is 30)
TTL: 10 hops (default is 5)
Zero Config: Enable (default is disable)
After saving those settings I then restarted the chromecast and went through the connection initialization on the chromecast app and it now connects / works
It also worked for me
Comcast has 15 types of modems, when did you get it, what does it look like?
Does the name of your WiFi have a space in it?
Just my advice...
But anyone using an ISP provided device that has it's own WiFi is using a router and should go out and buy your own then have their ISP put that device into Bridge mode.
You will have a much easier time with getting streaming and other servers to work and you will have complete control over your home network....
As opposed to someone who lives 100's or 1000's of miles away who may or may not speak your language!
