Keep losing internet connection

Try this fix.  I was powering down the Nokia Gateway, and plugging it back in rather than using the reset port.

 Please follow the step below to reset the gateway device.

Press-and-hold a paperclip in the Reset
port.

The LCD screen will display a counter. Before the counter reaches 4, withdraw the paperclip.

The T-Mobile Nokia 5G21 Gateway will automatically reboot.

Once it is rebooted, wait for 2-3 minutes and then pair the device and confirm if the issue is resolved, I am here with you to help you.

After I reset the Gateway, I didn’t have to re-pair any of my computers or TVs.

Sadly, I wouldn’t recommend Tmobile home internet as a primary gateway for multiple streaming devices in the home. In theory it works but cellular networks are historically congested at peak hours. Stick with a solid ISP in your area with say, EERO mesh WiFi and you’ll rarely have issues. If you have no choice, place nearest a window and hope for max signal.
