Fire Tv Stick distance from router

One of my 3 exploited Fire TV Sticks is about 40 feet away from the router and has been working fine even though ithe router is inside of a cabinet behind a wood door and the door to the room where the stick is located is usually closed. I’ve recently begun using IPTV Smarters and also trying out XCIPTV players for IPTV viewing. Both of these players were working at first and now both have gone into non-stop updating which never ends. Seems like an endless loop situation on both players. Could the distance and obstructions be causing the problem? And yes, I’ve already searched for answers. Please don’t attack me if this topic has already been discussed.

Don’t think it will be distance especially if it was working before to confirm move it closer and then you will know

I was wondering if IPTV needs a much stronger wifi signal than other Firestick apps.

Not as far as I know if they were working Dont see that is problem maybe site is down maybe if you have something like surf shark turn it off then see if update works then reconnect it
