Can't connect Google Mini to T-Mobile Home Internet

I agree 100% with you I just purchased and set up the gateway router a week agon and this is an ongoing problem hope T-Mobile works this out and fast 

I called T-Mobile and at first they did not admit that there was an issue but I told the guy to google this and you would see there is a problem. T-Mobile needs to address this if they want to be successful in their internet rollout. 

After reading this thread I see I am not alone, This is very frustrating. I have two Google mini neither will work but I have 3 Amazon echo dots all working fine, sure would be nice to get a fix from T-Mobile for this issue.

I am having the same issue, but I have one Google Home device working, but the other will not work at all. I am most likely going to cancel this service as the downloads suck and my ping test is over 200+. I did all of the restarts, reset, reboot, and reached out to customer service with no luck. They never return calls or follow-up. Therefore, I will take my business elsewhere.

It’s not just google devices, it’s all google services, including gmail and many others.

Changing your dns doesn’t matter. 

You can use a VPN, and get around it to get your google things to load. Otherwise, the router is for some reason blocking google IP addresses. This is highly frustrating.

I just got T-Mobile home internet and switched all of my devices to use it and I'm having the same issue with the Google mini. It goes all the way through setup and then fails and doesn't work.

Having the same issues and I've tried everything! The old LTE Gateway worked fine in this regard. Why is the new Gateway crippled, why are certain settings not available, and why won't my Google Home devices connect or stay connected?

+1 here. Please help, someone from T-Mobile! Definitely an issue. We need some firmware update from T-Mobile on this.

Several other threads here mention that Google devices work fine if you use your own WiFi router (turn off the WiFi signal from T-Mobile, plug your other WiFi into the Ethernet cord). It's ridiculous that this is the only solution.

(There's also some incorrect thread here mentioning T-Mobile blocks third party DNS providers, and points to this as a possible cause of Google devices failing. I tested this and found it to be false; using a third-party DNS provider like Cloudflare or Google works fine so that thread is a red herring)

In my case, my Mini speaker eventually did connect (I just left it in the broken state "there's a glitch" overnight). Now I can ask it questions and get a reply but can't stream any audio by voice ("play the news" or "play some music" both respond with "ok" and play nothing) or cast audio from an app like Spotify on my phone/computer.

I'm having the same issue.  I was finally able to get it to connect by playing with turning bluetooth on/off during the setup and not having my Google Assistance device automatically reconnect to my home wifi.  But to be honest, I don't know what actually made it work.  However, the next morning it had disconnected again and I've been unable to reconnect again.  Has anyone found a solution?

Message me if you find out.
