Have to reboot gateway every morning

For the last 3 days, none of my devices have connectivity  to the internet.  The gateway shows that devices are connected. T-Life shows that no devices are connected. I have to do a hard reboot - take power cord out for 10 seconds, and then will finally get internet. 

Whatever is happening, is occurring early morning - around 4 am central time.

I had this same issue a few years ago and posted in this forum but I cannot find the resolution. The issue is definitely on TMobile's end. Very frustrating.
