I have a 42 inch Samsung hdtv , I have it hooked up to my desktop and laptop. My wireless internet signal is somewhat weak, 3/5 bars. But it greatly impacts my internet performance, cant play most games online, and browser is very slow , youtube videos hardly load etc. Weird thing is... when i flip my laptop screen up, my wireless signal goes to 5/5 bars and runs flawlessly. I was using my laptop for the longest time with 5/5 bars at all times, until i connect it to my HDTV, it ran fine for a couple days, but then the trouble started. I am quit positive it is an issue with the TV, but why?
