Damn, had the iPad since last Monday and considered myself lucky to have gotten a fully working iPad. Didn't have any issues at all with regards to wifi connectivity. Then, 2 days ago, I started getting "invalid password" messages fairly regularly. Now today I don't get those so much as I just lose connection entirely. No error or anything, the connection just disappears from the status bar and I have to go back into settings to reconnect (which more often than not requires me to forget the network and start again). I tried resetting network settings and it seems to have gotten worse. Are we thinking this is hardware or software related? I don't want to exchange it if I don't have to. EDIT: happened again! Had a solid connection as I typed that message. As soon as i hit submit, i get a "connecting..." message. It then asks me which network I'd like to connect to. I select my network (the only option, it seems). It tries, then says unable to join network. Curses.
