5g home internet - phone not autoconnecting..

I was thinking of regular phone calls, because your Wi-Fi connection hasn't been continuous so far.  If you get a good T-Mobile cellular signal in your home, use that.  This isn't the same as turning off the Wi-Fi.

For Teams/Zoom I would use Wi-Fi, but of course your Wi-Fi could disconnect.  I hope not.  I hope you have a good experience with TMHI.  It took me 3-4 days to get all my devices connected.  Since then, it's been solid.
