Hi all. I've been through the many wifi threads and can't find anything that replicates my problem. Basically, my new iPhone will connect fine to my D-Link wireless g router if the network is open or under WEP security (64 or 128) but NOT under WPA-PSK (TKIP) -- which unfortunately is what all my other devices use. So far I have: Set up a new network SSID. Tried to join manually through the phone's "other" network setting. Disabled MAC filtering. Re-enabled MAC filtering and added the iPhone. Rebooted everything several times. There seem to be some posts suggesting this may be a D-Link issue. Any 624 owners out there who have managed to join their networks under WPA? Anyone have any other ideas?
