Home internet modem keeps powering down and restarting
So, we had the Tmobile modem(the 5g tower... black box) for a few weeks now... worked great at first but now it continues to shut down every few minutes and restart. If it does it long enough I have...
If it is rebooting like that it might be the power adapter or the gateway has a problem. Contact support or touch base with a local T-Mobile store to see if you can get a replacement. I would see if they will provide both but try the power adapter on the original gateway before you swap the SIM card out etc… Reduce variables to know if it is only the power adapter. That is if you really want to know.

(Just note, I am still running dual WAN between Cable and T-Mobile Home Internet. So that's why I can still email myself alerts off the firewall.)
I decided to give it a whirl and switch out the stock power adapter to my Anker USB-C (up to 100 watts) adapter I use with my laptops. The stock one says it is 15 watts. The cycle of rebooting for me stopped. After a few hours, I switched it over to a leftover Chromebook USB-C wall adapter that is good for 45 watts. No hiccups or issues after a few more hours that I've seen thus far.
I’ll edit / post an update if anything else comes up, but the recommended solution definitely was worth a try for me.
How has it gone since then?
