Problem with gateway losing just 5G signal

Aloha copz1998! Thanks much for your help! I have some new info you may find interesting! (Understatement). But first to answer your question. No, I can't determine, thru any source, WHICH tower my gateway is connected to at any time. It seems ONLY T-Mo personnel can do that. I DID use cellmapper to "look at" ALL of the towers near me. There are actually 2 T-Mo 5G towers I "should" be connecting to - as I previously noted.

So here's the new info: researching online, I discovered that T-Mo gives older 5G Home Internet accounts LOWER priority than 1) ALL 5G mobile phone usage; as well as 2) NEW 5G Home Internet accounts!! Yup, that's right, T-Mo "rewards"  its loyal customers by THROTTLING access to it's 5G towers! As a type of back-handed confirmation of this, I submit this. I have a new 'friend' inside T-Mo Support. That person went to their boss with my problem. The boss suggested that I close my current 5GHI account and open a new one!!

And here's a new development - also with my research, I discovered that the Arcadyan gateways, (which I have) even though they are the best 5G gateways T-Mo has supplied so far, have a problem with SIM card connectivity! I mention this because, on the 3rd day with my newest gateway (Arcadyan #3, for me), I lost my 5G signal (again)! So, I had T-Mo send me a new SIM card, as that had never been replaced, and was the last possible fix I could try. (I'm STILL waiting to hear back from the 5GHI engineers.) Well, installing the new SIM didn't help squat! So, in my frustration to stream content on my TV, I decided to run an Ethernet cable from the gateway to the TV. While I was doing so, I knocked the online gateway onto the floor. Guess what happened? EVER SINCE THEN I have had 5G data flow! Now, while I certainly would NOT recommend people drop their gateway onto the floor (YMMV), doing so did the trick for me!!
