Wifi hotpsot logs out periodically.

Wifi hotspot logs out periodically, have to login again. Did not occur on this account until I moved to a new location in November 2016. I moved 2 miles but it did cross a county line. The TV, believe it or not, now gets a crappy 480p signal whereas before it was at least 720p.  And the channel lineup is worse or at least confusing.  Moved two miles.
