5g home internet - phone not autoconnecting..

I found a workaround, which was to use a wifi range extender I had around. I use the range extender to connect to the Tmobile gateway, then connect my phone to the network provided by the range extender.  I can now turn my phone wifi on and off and it'll automatically reconnect to the range extender network. Which so far has remained connected to the gateway. I'm using a TP link RE200. On my phone, the download speed is half what it is on my desktop which is connected (wirelessly) directly to the Tmobile gateway. Since I don't do a lot of heavy activity with my phone I think this should be OK.

Is it possible your phone is looking for the old network?  Is there a setting to "Forget This Network" (the AT&T home internet)?

Thanks for the reply. I have already done the "forget this network" on the old network, and there's no longer a saved password for it, so it's not connecting to that.

I did see this issue posted in the forum about a year ago that other people were noticing the same problem, but there was no solution posted. Hoping someone else has had the problem more recently and has found a resolution.

Try rebooting the gateway and your phone. 

That didn't do it. I called Tmobile tech support and he hadn't heard of this. We tried creating a new network in the gateway at 2.4g, and it does the same thing.

If I turn my phone wifi off then back on, it doesn't auto-connect to this gateway. And actually it has disconnected itself several times today. It's one floor above me, right above me, and the wifi signal is full strength.

I don't know what else to try, neither did tech support. My laptop is connected to it without issues when I turn the wifi off and on again.

I'm glad you got it working.  You might not want to use Wi-Fi calling.

May I ask why you say that? Would that apply to Teams/Zoom calls with my phone as well (via the extender being connected to my phone)?

I was thinking of regular phone calls, because your Wi-Fi connection hasn't been continuous so far.  If you get a good T-Mobile cellular signal in your home, use that.  This isn't the same as turning off the Wi-Fi.

For Teams/Zoom I would use Wi-Fi, but of course your Wi-Fi could disconnect.  I hope not.  I hope you have a good experience with TMHI.  It took me 3-4 days to get all my devices connected.  Since then, it's been solid. 

I recently switched to T-Mobile Home Internet, and neither mine (Pixel 4) or my daughter's (iPhone XS) automatically connect, upon returning home or restarting our phones. It's really not a major issue, until I forget to reconnect it, and use 2gigs of mobile data, when I only get 5 gigs of mobile data, per month to begin with. I'll try the wifi extender, that's a good idea. 

I have the same problem. I also used a range extender to auto connects when I arrive home. The extender acts like a router.
