Are you trying to connect to a 5GHz wifi signal? If so try connecting via 2.4GHz. If you're running 5GHz and 2.4GHz on the same stack, you could try splitting them up. Since 5GHz has a shorter range, maybe the TV is on 5GHz and losing the signal from time to time. My TV was having connection problems when it was connected to my AT&T Uverse gateway directly because it defaulted to both bands running together. It didn't like splitting them up either as that caused another problem. I finally picked up a Linksys router and split the bands up. Now I have no problems with my LG TV staying connected.
