Has anyone been able to get a wireless connection using WPA-PSK between Airport Express and a D-Link 624 wireless router? 128 bit WEP works just fine on my iBook, but I can't seem to get the WPA-PSK to work. I get a "wrong passphrase" error. I've changed the passphrase on my router to make sure I didn't have any spelling mistakes, but still no go. Has anyone else got this to work?
