My att bold 9900's wifi antenna is trash. I have 3 bars signal In my living room where my router is, but one room away in my bedroom I only have 1 and sometimes it loses connection completely. Even at my restaurant, I lose connection if I go behind a wall. My business partner has att iphone and has wifi connection everywhere in the restaurant. So my question is...are there any good wifi booster apps? Or anything I can do to fix this?
Thanks guys!!
