Roku TV no longer works with Google Mesh WiFi

I was trying to load YouTube, Amazon Prime, and NetFlix on my Roku TV today. All said I have Internet problems. Testing the connection showed that it had excellent connection to the Google Mesh WiFi....

Wondering since your Roku device is able to connect to both your Xfinity router and the Google Mesh, has this always been the original setup? Using Google mesh system, normally the Xfinity router should be in "Bridge" mode. (will not hand out DHCP addresses).

If your Xfinity gateway is just a modem, then this would not apply, but since the device (RokuTV) is connecting to it wirelessly (wifi) on the 2.4ghz band, seems that it is in Router mode and handing our DHCP addresses.

----

There are ways to use 2 routers on the same network in Router mode, but each LAN IP would need to be different. (both cannot be using the 192.168.87.x gateway IP.)

----

If the Xfinity router is not in Bridge mode, you may be running into a double NAT issue.

----

Otherwise, maybe double check your Google Home app and Xfi app and make sure you did not accidently "Pause" your internet connection for the RokuTV. (wifi pause).

Hi AvsGunnar,

Thanks for the reply.

My Xfinity modem is also a WiFi router. I set it up to be 192.168.0.x. It does have it's own DHCP.

My Google WiFi Mesh main node's WAN port is Ethernet connected to one of the four Ethernet (LAN) port on my Xfinity router and uses 192.168.86.x for its WiFi. So Google Mesh WiFi has its own DHCP.

I made sure to check and ensure my Roku TV was not paused in the Google Home WiFi app.

This set up was working great in the past and I have not changed any network configurations/settings for a long time. That's why it's weird that it just started having problems, making me think it's either a Roku TV update or Google Mesh WiFi firmware update that caused this.

    I just ran 

    sudo nmap --script broadcast-dhcp-discover

    and there's only one DHCP server on my Google Mesh WiFi.

      All looks good with your setup.

      How about a simple ping or  nmap ping while you are on the Google (192.168.87) network for the Xfinity router (192.168.0.1)?  While on the Google network, can you see a response to the Xfinity router?

      -----

      If all the channel/apps are having the same issue, then just having a problem accessing the internet.  Would try changing DNS to default Google servers 8.8.8.8 and 8.8.4.4. (initially on the Google mesh).

      Then check actual physical connections.  Maybe just unplug the ethernet cable from both routers and then reconnect.  Try different LAN ports on Xfinity router.  Try different ethernet cable.

      At first glance, looks like Roku device can connect to Google network, just having issue accessing internet (or the Roku servers are having an issue "how" you are trying to connect to them) when connected to the Google Mesh.

      Can you bypass the Xfinity router and connect WAN to the Google Mesh or is the WAN supplied via a cable connection needing the Xfinity router to be in place?

      If all else fails, I would try Factory Reset of the Google Mesh.

        Hi AvsGunnar,

        I used another computer on the same 192.168.86.x subnet (Google WiFi Mesh) and was able to successfully ping the Roku TV and my Xfinity Router gateway (192.168.0.1).

        ------

        Yes, all the channels are having the same issue. I changed DNS on my Google Mesh WiFi to 8.8.8.8 primary and 8.8.4.4 secondary. Roku TV still has the same problem.

        ------

        I unplugged the Ethernet cable connecting my Google Mesh Primary Node and the Xfinity router. Replaced the Ethernet cable and then used a different LAN port on the Xfinity router. Problem remains.

        ------

        Unfortunately, my Xfinity WiFi router is a Cable Modem/Router combo, so I can't bypass Xfinity router and connect Google Mesh Node's WAN directly to the Internet.

        ------

        I tried factory reset the Roku TV and had some additional interesting findings. After reset, one of the first step is to connect Roku TV to my Wireless WiFi. I tried my normal Google Mesh WiFi, and the factory-reset Roku would not connect to it.

        I then connected Roku TV to my Xfinity Modem/Router WiFi, which was successful, and the Roku TV auto updated firmware. After firmware update, I can connect Roku TV to my Google Mesh WiFi again. But then all the channels still won't load with the same problem.

        Meanwhile, my other devices on the Google Mesh WiFi are working fine.

        ------

        My last resort is, indeed, to factory reset my Google Mesh WiFi. Still puzzled at Roku TV's behavior though, and why my other WiFi devices (including my computers) are fine with Google Mesh WiFi.
