I have the 64 gig wifi+3g ipad and until today it has been working great. I have a wireless router at home & always have 3 full bars and have been able to view utube videos anywhere including my garage. To day I went to our library which has a wifi hot spot and turn off the 3g. I sat next to a young lady and her laptop had 4 bars and good performance. Well my ipad had one bar and would not load the browser. Moving around I was able to have 2 bars at the most and it kept dropping to one bar. If this is always the case I guess I am glad I have the 3g. I did have it in the Apple case and wonder if that affected the signal? jim_joh
