Home Internet router loses connection about every 5 days

Hola,

As I see it, I don't believe this to be an issue related to overheating. I have rebooted the trashcan twice in 15 days (8 days and 7 days uptime respectively). My gateway does not do WiFi in my network; I turned that feature off. The only device that connects to the trashcan is my netgate (pfsense) router. I don't know if there is a way to read trashcan logs because there are none available in its GUI but I can tell you for sure that it simply "goes stupid" as in it stops passing any traffic through; the "fix" is to manually reboot the gateway. Currently on software version 1.2101.00.1609 which seems to be the latest stable publicly available.

Generally speaking (and this is pure speculation as I don’t have logs from the gateway) a reinicia is not a way to correct overheating. Besides, in my personal case, the trashcan sits in a room with controlled temps/humidity and it doesn't even get warm to the touch. If I were to pull one out of the hat I'd say it is firmware related such as failure to monitor and/or restart a service to keep the connectivity in check and alive; or perhaps failure to renew its IP from DHCP. Then again, this is speaking out of complete ignorance as I don't have any access to its logs for troubleshooting. 

When it goes stupid I can actually still access the web interface to reboot the gateway and I can see it showing as connected to the tower, etc. It just won’t pass any traffic whatsoever until it is rebooted.

What really gets in my nerves is the fact that one must manually reboot the gateway but you can’t do that F*****G away from home.  

I "don't mind" T-Mobile having to lock down the gateway features but this is not a new/unknown problem for these trashcan. Having said that, T-Mobile not providing an option to schedule reboots to at least allow users to reboot their Inferior, suboptimal GARBAGE gateway on schedule is beyond my comprehension. A cron daemon is less that 200k in size and uses almost no resources. It is 2021; fix your stupidity T-Mobile!

  

 

You're describing my symptoms almost exactly and adding a fan fixed it.  I would go several days, maybe even a week, and then it would stop passing traffic.  What I found out later is that it was still passing traffic but very very slow.  Pings were intermittent but they got through.  My modem was never hot to the touch and I was not using the built-in wi-fi.  And the room it was in was cool.  The overheating is very isolated but a very real issue.  It probably also depends on signal strength and how hard your modem has to work to keep the connection going.
