5g home internet stuck on 4g

UPDATE: I took my replacement modem to a local store to see if they could replace it... while there I decided to plug it in to see if it gets 4G or 5G... Of course they plug it in and it picks up the 5G signal... They noticed that my modem was somehow attached to the address on file for my parents (who are on my account) and wondered if that's why it's not picking up 5G at my house so they update the address. I got home and plug in the modem hoping it picks up the 5G signal (which it did fine before) and no luck... still on 4G. Tried multiple locations throughout my house and only 4G is getting picked up even though it used to get 5G just fine… UGHHH...

Do you have a TMO phone?  Is it getting 5G?  If so, tell that to customer service so they will actually look into the problem instead of the default deny/delay.  Also, demand service credit.  If they are not providing 5G, you should not be paying for 5G service.

Yes, I get 5G on my phone everywhere in my house which is why this is even more puzzling.

See my first reply.  I think the 'engineers' have to add your SIM/device to the access list for 5G.  Dont forget to ask for service credit.

Hm… lost 5G again.  OK, now I think this is what's happening.  The Home Internet Gateway are allowed 5G only on one tower.  When that tower goes down, you lose 5G.

This conclusion was from talking to another rep this week who confirmed the tower closest to me (I know that tower) was down and is supposed to be up this week (explains why I got 5G back on Monday) and is probably down again (may explain why I lost 5G again) or this one tower’s 5G is too congested.

Update, I moved my gateway to the corner of the house closest to the tower and got 5G back.

I just found out that my gateway displayed "4G".  I just unplug it and plug it back again, and it becomes "5G".  I do not why?  hope this does not happen frequently.  The speed in 4G is really much much slower.

I finally had a BRIEF connection to 5g again this time band n41, and lte when to b2 vs b71. speeds went back to 300down 105up… then the next morning noticed 35 down, 1.8up...looked in app and again no 5g connections, and lte back on b71.  I lost 5g connectivity over a month now.  I would be happy with LTE on b2.  Now it only locks on to LTE b71

Contacted T-Mobile tech support last night with the same issue and found no resolution.  Some of my web pages were slow to populate so I checked the browzer and found 4G.  My wireless printer connection failed as well.
How is your speed?

I have been using it for a long time with 300+ download and 100+ uploads. For the last 1 week the gateway is stuck at 4g. I read thru this thread mentioning tower issues. Anyone have a solution that is successful ?.

I am having the same issue. If it would just stay on 66 and 41 I am good. My phone never leaves 66. When the gateway gets on 71 4G it will not pick up 5G. I am thinking of disconnecting the low band antenna inside the gateway and wrapping it in electrical tape to try to force it to connect to 66 and 41.  Anyone tried that yet?
