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!

Try rebooting the router.

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.

Try a VPN ?
Sent from my XT897 using XDA Premium 4 mobile app

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.

Phone can't find chromecast in CM11 when connected to VPN

Hi all,
not sure this is the right forum as I haven't altered my chromecast in any way... Anyway, I used to connect my Galaxy S3 running CM10.2 to my chromecast while being connected to a VPN (PIA). Yesterday I updated to CM11, reinstalled all apps using TB, and found out that my phone now can't see the chromecast anymore when I'm connected to the VPN. When I disable the VPN, the chromecast shows up fine. Has that happened to anyone else? I didn't change any settings so I assume it's somehow related to CM11 / Android 4.4. To be clear, I don't need to have the chromecast connect through the VPN to watch Netflix for example as I am in the US, it's just inconvenient having to disable the VPN every time I use the chromecast...
Any ideas/suggestions/explanations are much appreciated!
Cheers

Sounds like in your new configuration the VPN connection has precedence over the local network. I have no clue how to change that, but hopefully you do.
Sometimes there's an option akin to "route all/local/Internet traffic through VPN" that controls what traffic hits the VPN.

This happens to me now as well. I no longer use a vpn for this reason unless you can configure your router to use it. Basically it looks at your chromecast as being on a different network since it isn't on your vpn. This is the case for cm11 and stock roms on my Nexus 5.

that's...unfortunate... makes me consider going back to cm10.2...
thanks for your replies!

Unable to cast BBC iplayer tab in Spain through VPN

Hi,
I can't cast the BBC iplayer tab from my chrome browser (OS X Mavericks) through PureVPN or any other VPN (as I live in Spain) since the iplayer got updated and incorporated the cast button.
Before the update when I had the choice to carry on using the old version of the iplayer, it worked fine but now after the update all I get on my TV is a message saying "Ready to cast" and nothing happens.
Will it be because the player can detect that my Chromecast is actually connected in Spain?
Is anyone having the same problem?
Any ideas/solution would be greatly appreciated.
Many thanks.

It's because iPlayer is trying to send Chromecast a link to pull the video directly, but Chromecast itself isn't on the VPN and still appears to be in Spain.
Sent from my Nexus 5 using Tapatalk

That makes a lot of sense, thanks. Do you know how to connect the chromecast to the VPN?

Hi,
Good article but it doesn't explain how to set up a VPN on chromecast, from what I can see I don't think it is possible.
Thanks anyway!

You can buy a VPN account and setup on your Wifi Router , and give VPN access to all devices, im doing that long time ago , to see Netflix USA and Pandora .

Currently you can't really run a VPN client on Chromecast (in theory if you're rooted it's possible but I don't think anyone's tried), so your best option is to set up VPN on the WiFi AP/router that Chromecast connects to so its traffic goes through the VPN. You might also have to block/reroute the Google DNS servers to force Chromecast to use the VPN DNS, but I'm not 100% sure on this.

If the router connects to a VPN rather than use DNS redirection, I would think that covers it because Google DNS would be accessed through the tunnel.

As other have implied, and said, you need to get your routing device to connect to your VPN service. Then your devices should get the VPN dns and IP information pushed to them.
I have done this with using the BBC iPlayer on both my Note 2 and ASUS Infinity Pad Tablet and Chromecast. Used my GN2 WiFi hotspot service while it was connected to my VPN service. I connected both the tablet and chromecast to it. Then I was able to cast videos to the chromecast from the tablet.
You just need to figure how to connect your router to your VPN service, if possible. Not all VPN services allow this.

Unable to cast netflix

I used to use the netflix on daily basis until about three weeks ago I started to get the following message after a long time displaying the netflix splash screen on my TV: "Humm... It seems we're unable to connect". And then the netflix closes after 10 seconds. Every other chromecast official app works good, but Netflix. I also noted that if I restore the chromecast and launch netflix, everything will work. But if I cast other app, as YouTube for instance, and then return to netflix, I'll get the problem again, requiring another restore.
My chromecast software version is 16664.
Is anyone experiencing the something like that?

Just to confirm, you're not using any DNS relocation/redirection (Unlocator, Unotelly, etc), right?
I just used Netflix the other day, and I'm still on 16664.
It's weird that everything else works except for Netflix, and also weird that factory reset makes it work. Could be a bug or perhaps something with WiFi connectivity. You don't have a WiFi repeater or multiple APs using the same SSID do you?

I use regular DNS. I also tried different WiFi routers and I always got this issue. Rarely Netflix works without need factory reset.
I was wondering if it could be a problem with the chromecast cache. Do you know a way to clear the cache without factory reseting?

Not that I know of... however, since the Netflix app is stored on Chromecast, there's a small possibility that it's a RAM or NAND issue on your Chromecast itself. If it's not rooted or special in any way, you might want to consider getting it replaced.
Or see if you can borrow another Chromecast to see if the problem is localized to your specific device.

This is new for me. I thought Netflix was loaded online. I'll ask a friend that has chromecast to test mine in his home and and borrow his chromecast.
I'll let you know the results tomorrow.
Thanks

I borrowed a chromecast and first time it worked. After casting YouTube videos and then return to netflix, same thing happened. My friend got everything working great using my chromecast.
The only thing that never changed is my cable modem, but I never change anything on it. Moreover, why this is happening only with netflix and why it works if I factory reset are still a mystery.

Perhaps you are seeing the first case of Net Neutrality biting you in the ISP?
See if you can reach Netflix via the browser...

I don't think so. I can access netflix anywhere else: tablet, phone, ps3 and computer. Besides, my friend use the same isp.
The only other place I having trouble in access netflix is my old Asus cube that I had retired since I got the chromecast last year.

Quite the puzzle...
Since your Chromecast works on your friend's network, and your friend's Chromecast shows the same behavior as yours on your network, the breakage factor definitely seems to be something about your network.
I really can't think of your cable modem being an issue unless isn't going bad (if it has an interface, look for excessive errors and/or poor signal quality - for example, Motorola SurfBoards usually have an interface at http://192.168.100.1/).
As your friend is using the same ISP, I would compare your router settings with his - ISP login type, routing and DNS in particular.
Of course if you have different routers then the router itself is still a variable.

I'll try to share my mobile Internet connection as soon I get back home to see if it will do the same.
Also I'll try to look the router log to see something.

I tested chromecast connecting to my phone in tethering mode. Netflix worked everytime. But when I got back to my regular connection, the problem appeared again.
So the problem seems to be located in my cable modem that also is a router.

Ok first question...do you have another router connected to the Modem Router? Are you using the Modem's built in WiFi or this other router's?
If you have another router then chances are likely you have a double NAT situation which is messing you up.
Check your other router and see what IP address is has listed under Internet connection...If it is a 192.168.xxx.xxx then it's a double Nat and you need to call your Cable company and have them put the Modem into Bridge mode.
If you do not have another router and use only the Modem router then you need to call the cable company and have them change the settings on the router to allow multicast and UPnP...Maybe a few other settings as well. Tell them what you are trying to do they have probably gotten lots of calls from others with the same issue.
Me personally I prefer to use my own router and have them put the Modem into Bridge mode so I have full control over the network and don't need to call them whenever I have a problem or want to change settings.

My cable modem a public IP provided by my ISP, and a private IP that is 192.168.0.1. My router has a WAN IP provided by my cable modem (192.168.0.xxx) and a LAN IP 192.168.1.1. My chromecast used to be connected in my router LAN, but I changed it to connect directly to the cable modem router. I'll try to put the cable modem in bridge mode to see what happens as I have full access to its configuration.
Thanks again

Yep that setup causes a double Nat situation Which doesn't work well for most networking applications....
Especially since you are also dealing with Two different Wireless networks.
Best setup is to have the modem just be a modem and send public IPs to whatever connects to it.
Then you won't have any Nat translation issues PLUS you get the ability (if your Modem has multiple ports like most Modem/Router Hybrids do, You can get a public IP for any device directly connected to the Modem which is good for running servers and for testing router issues.

Problem solved!
I turned off the wifi on the cable modem and put it on bridge mode, letting my router deal with my network. Netflix is now working good on both chromecast and Google tv.
However I believe the problem was related to a still unknown setting in the cable modem as I left it operating alone and netflix was still not able to load.
Thank you very much for the help. I really appreciate it.

it may very well have been a Router issue with the Modem...But now that it is only a Bridge the other router's settings will handle all the communication needed for the CCast and it should work...
As long as the settings on the second router were not the issue in the first place.

Is it possible to remotely cast a chromecast from a different network for signage ?

I'm a beginner in ChromeCast development, I've searched for a long time to have an answer on the possibility to remotely access, control and cast a chromecast device for digital signage, in different networks.
While searching and understanding the mechanics of chromecast, the answer seems to be "No !" but I've found companies selling solutions that are doing a similar thing.
So if someone knows a way to do that please inform me. (Or if it's impossible to do that).
Thank you !

I already setup VPN (PPTP Server) on my Mikrotik Router, can ping that chromecast. But, how to connect to my chromecast, I can't see my chromecast on googlehome apps, since googlehome apps require wifi to connect chromecast.
Please somebody help me..

You will probably need to set up an mDNS forwarder or enable multicast forwarding so the app on the remote network can discover them.
Be careful as you can easily cause a loop.
