I've tried every recommendation in the book restarting the "T-Mobile" device, the mini. It will go through the entire process of adding the device and at the very end, after it's verified the connection, it suddenly says it can't connect to the network and fails the addition.

I have gotten Google Home hub, google mini and camera all works. The way to solve your problem is to go on T-Mobile internet app and hide your first net work set up which is 5ghz frequency that will interfere your devices. Only keep the net work with 2.4ghz frequency.

 I also tried most of the suggested fixes and none worked for me, so I deleted and reinstalled the google home app. Then I setup a home in Google home and connected a none google device that was working on my T-Mobile WI-FI in this case a robot vacuum. Now that my Google home had a device associated to T-Mobile Wi-Fi, I was able to connect Google mini and Google home speaker,

So, I had the same problem, but here is how I got it to work. I RESET all my google minis to factory reset. Then I erased ALL of my homes. I started from scratch with all a new home and devices on my network. Then it worked like a charm. 

So if the answer for everyone else is as simple as it was for me, it's almost blindingly obvious. Make sure you factory reset the Google Home Mini with the tiny round button on the bottom. Hold it for like 30 second, then set it up again. Voila.

This was the answer for me! I am up and running. Thank you so much. Been trying to connect to the mini for 3 months!!

I finally got my Nest speaker groups to work by using my own router. I factory reset my ASUS router and connected my Nest devices on its 2.4Ghz band. I turned off each 2.4Ghz SSID on the internet gateway, but use it's 5Ghz band for my computers and Chromecast 4k, because the speed is so much greater. I would have preferred to use T-Mobile's internet gateway alone, but it just wouldn't work that way.

Only thing that has worked for me is to hang another router off the Home Internet box using an ethernet port on the HI can and connect all of my Google devices to one of the SSID’s defined on that (ASUS) device.  I’m using the 5 MHz band and it works ok. Didn’t bother trying 2.4, but it would probably be fine also.  Single google devices worked ok off the Home Internet router, but groups (e.g. speaker groups) would not.  Tried all sorts of “fixes” to no avail.

I tried a few different things and it finally worked. One of those was building a new group and basically putting everything under the new group. Then deleting the original group. Sorry can't give you the order of things, wasn't tracking bc didn't expect it to work. And adding the new group was a pain. Good luck!

Actually mine is now all working as it should - Google speaker groups, thermostat, lights etc. Make sure that all of your Google home devices are using the same 2.4ghz band connection and not the 5ghz band that TMobile defaults to. Even if one speaker or device connected to Google home is on a different band then it will throw everything off. This includes your smart phone, tablet, Chromecast and/or Chromebook in my case. Essentially i use the 2.4ghz band for all Google stuff (even though Google claims it works on 5. It does but with caveats). Anything that uses your Google home should be on 2.4ghz. i have wifi bulbs and smart plugs that aren't Google but are controlled by Home so those are on 2.4ghz as well. I use the 5ghz band for everything else...my work VPN, LG TV etc. 

Thank you for your suggestion, but my speaker groups still won’t function.  I moved all devices to the same 2.4Ghz network, and even deactivated every 5Ghz SSID, and still can only cast to one device at a time.  My gateway has the 1609 firmware, not the newest 0.2103.00.0338 version. Maybe I will try going back to my ASUS router, but the last time I did that in December, my download speeds dropped from well over 100 Mbps to an unusable .7 Mbps.

My google mini works fine as an individual speaker but it won’t play as a group of speakers (multiple speakers in different rooms). Any known fixes for this? I set up the 2.4 network thinking that would fix it (since that’s how it works with my current ISP) but no dice. Support from Google and TMO can’t really figure it out either. 

I have this same issue. I've tried so many things, including factory resetting all my nest speakers, and they never work in groups, but each works perfectly on it's own. There's something odd going on either with Google or T-Mobile that is keeping speaker groups from working, but I can't find any solution. Does anyone have speaker groups that do work with the home internet gateway?

I think I changed it because it's not letting me in

I never even use those extra windows that require a password. The GUI is very limited in terms of custom configuration. Is it something you need to change because you are trying to install an external router or what?

If it’s important and you’re willing to start all over again, I think you can do a factory reset of the gateway by depressing the hole, which is located in the inset panel on the gateway, holding for a time, and then starting all over again with the setup. I think that should allow you to lose your old password that you forgot and start all over again.

 

 

I'm trying to access the main settings for the network using 192.168.12.1 but looks like it has different password for the admin, does anyone know the default password? I tried the one under the router already

I’m assuming you selected “System” and it’s asking you to enter admin and a password. The password is the one on the bottom of the gateway. After entering the password, the first screen I come to is one that allows you to change your password to something easier to remember or enter. Do you think you may have done that before and forgot?

Good suggestion. I recommend to people that when they’re setting the gateway up for the first time, they get it working with one device, whether it is a phone or a laptop. Then after it is all set up, restart the gateway and restart your laptop or phone, and make sure you’re all signed in, signed up automatically, and that the internet works.

Then change your SSID name and password in the app to what  you had before and that should add all your devices, and restart the gateway yet again after doing that, because if some of the devices don’t connect the first time, they will connect after the restart after the old SSID name and password has been established.

After all, the Google Home Mini or all these smart devices, are just using wifi, and wifi is wifi, whether it is coming from the gateway’s router or a separate router.

As far as the factory reset on the Google Home Mini, first I’d try just unplugging the mini and plugging it back in, and as long as you are using the same SSID and wifi password as you had on your old setup, it should work. Just doing that can kind of re-register it with the wifi network.

Lastly, sometimes the Google Home experiences some quirks of its own that are unrelated to your home internet. When I first got my Google Home mini like three years ago, it was so slow, and barely worked. I got on the online help with a rep and explained that I’ve used computers for 50 years and what am I doing wrong. It turned out Google Home was having a problem at that time. The next day and for months after it worked  great.

I tried all the above with T-Mobile support (and Google support) and still couldn’t get the two to work together. I just got off the phone with T-Mobile support and they shipped the Home Internet Gateway router knowing that it doesn’t work with Google Home devices. They may offer a firmware or other update in the future that fixes the issue, but for now, I was told that they don’t work together.

My Google Home Mini works normally with the gateway, from the first day I set the gateway up four months ago.  However, I didn’t try to  configure it. I kept the wifi password the same as it was for my old DSL modem. At first, when I set up the gateway, I went by the number of characters they suggested for the wifi password, or whatever, and once I had one device set up, I used the “change the wifi password (SSID)” function in the app, changed it to my old wifi password and all my smart devices connected normally.

There are about a dozen known quirks of T mobile home internet, and not working with google home devices (including the Google Home Mini) is not one of them.

There are at least 300,000 users of T mobile home internet and probably more than a couple thousand who use Google Home devices. It’s so important to me, I don’t know what I’d do without it, if it didn’t work. So, my suggestion is if you have your old connection service provider still, see if you can get the Google Home Mini working with that, and then do a factory reset (paper clip in hole at top of black inset on gateway), go through the entire setup again, but this time at some point, after one device is connected, change your wifi password to the one the mini uses in your old wifi setup, and see if that works. I wish I could be more help, and offer something simpler to do. Maybe someone else will.

The fact that T-Mobile shipped a router/modem knowing it wouldn’t work with smart home devices (or at least Googles) is the kind of thing you’d expect from one of those new brands that you see on Instagram lol. Definite hit to the T-Mobile rep. Got a credit on my bill since it basically doesn’t work. Going to give it a couple more weeks and if there’s no update cancel the service and go back to Verizon or something. Bummer.

So what has worked for me is to factory reset the gateway device. Once you set it up log into the settings online (192.168.12.1) and divide the 2.4hz and 5gz. But after you separate them go to configure ssid 5, under set ssid to configure make sure to go through all of them and turn off any "enable ssid" other than the ssid 5. For me the ssid 9 was named the same as my 2.4 and Google devices don't like 5gz. Sorry if this is confusing wording but I hope it helps.

The firmware update to 1.2003.03.0178 fixed the Google Home Mini issue for me too.

I was having the same issues until late last week when my firmware updated to 178 and *so far* everything has been working perfectly. My Google home/home minis/home hubs now all connect and have been working flawlessly and my Chromecast with Google TV is the same. Previously none of the Homes/hubs would connect and the Chromecast would connect, but some of the apps such as Hulu (regular Hulu, not Hulu Live) would not load. Additionally, when pressing the Google Assistant button on the Chromecast remote nothing would happen. Everything nowworks correctly. Fingers crossed that the firmware is pushed out to everyone soon and the fixes are complete and permanent!

I'm having the same experience now. I posted about two weeks ago at my wits end about the Home devices not connecting or staying connected. It seems that the new update and/or something that's been tweaked on T-Mobile's end has fixed some issues and all my devices have been connected for over a week now and all work fine. Before I was able to get them connected but they would glitch out or by the time I got home from work, they were disconnected. Fingers crossed. Now if we could just get some more settings and if my service wouldn't drop out so much during the day, then I'll be happy, lol!

+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.
