Hello all, My brand new iMac just came today, and I'm having a pretty irksome wireless problem. I'm at school right now, and in order to access the wireless network I have to run an "xpressconnect" program to authenticate my computer. The school uses wpa2 security. I can connect to, download, and run xpressconnect, but afterwards cannot browse the internet or do anything else requiring a connection. I can, however, ping google.com, which strikes me as strange. Tethering through my cell phone works fine, as does ethernet, but the ethernet here is incredibly slow and I'd prefer to be able to connect wirelessly - so it seems like some kind of driver or software problem (at least I hope it is, my display is perfect and I'd rather not risk exchanging it). Is there any solution, or should I just wait for apple to release a software update? Thanks.
