Unable to connect to wifi on my bedroom TV.

I have 2 TV's , 1 in the living room and 1 in the bedroom.  Nothing has changed in regards to the location of either TV or my wifi modem.  But all of a sudden, I can't get connected to the wifi in the bedroom.  Wifi is working everywhere else in the house just like usual, this is the only new problem.  No recent changes to my DirecTV service either.  Any suggestions on how I can fix this issue

Thanks,
