Home Internet Gateway Needs Reboot Multiple Times Daily, Internet Access Dropping

I started using TM 5G home internet a few weeks ago. 
Speeds anywhere between 80Mbps and 520Mbs down.
First day I had to restart once.
Since then it has been having to reset 3 times one day and then had it go 3 days between resets.
Same thing, speed trails off to nothing. App shows 3 bars on primary and 3-4 on secondary. App shows connected to internet but all devices show no/limited internet. Actually a couple minutes ago it actually recovered by itself for a change while I was typing this.
I added a USB fan under it since I saw temps of 150F using IR temperature reading which might be a little err high. Temperature is down now but connection still dies occasionally.
You definitely notice the stall if you are at home streaming or sitting at PC but I don’t know if it recovers by itself when I’m not in front of a screen.
I have one tower about 3200ft from me and another 5100ft from me. It looks like it reliably connects to the one 3200ft away. Sometimes when I restart it is bouncing between a couple of the cells on the nearest tower (Can see on the CID and CGI change.)  
Hard to say if they are servicing one or more cells occasionally and the gateway isn't handling the switch in cells elegantly. It does sort of remind me of the old days where your phone would sort of get lost on tower switches.

Hopefully they will have a new gateway coming that is more robust. I haven't called them yet because I've seen posts where people have swapped the gateway out and ended up at the same place.
