I got my A500 yesterday. I charged it and turned it on and followed the steps and connected it to wifi. It worked all right for a while. Unfortunately, the wifi won't connect any more. It was authenticated and stopped at "Obtaining IP address from 2WIRE118". I tried rescan, forget the password and input it again, static IP. None works. I saw a lot on internet about A500 wifi problem. Is it a hardware problem or software problem? Is it fixable? Should I exchange one from Amazon? Thanks in advance!
