I have had my iPad for over two months now and it has been a marriage made in heaven! BUT...for the past three days my wi-fi signal has been very poor. One of the things that I have really enjoyed is watching movies that are stored on my computer via Air Video. It has worked great. But now my average wi-fi signal strength is one bar! That definitely does not support streaming videos. I haven't made any changes settings-wise. I should mention that when I first awaken the iPad the signal strength is three bars for maybe ten minutes...then it drops and mostly stays at one bar. I'm very frustrated and don't know what to do to fix this! Any suggestions? It seems very strange to just have this happen out of the blue.
