I am having trouble with WPA on my Mac. I have a netgear WAP with WPA2-PSK [TKIP] + WPA2-PSK [AES] enabled. On the net we have an HP 3310 Printer, HP Pavillion running Vista, and my Mac running 10.5.4 - all configured with the same security. The Pavillion can access the internet and printer. The Mac can access the internet but can NOT print to or even PING the printer. When the network is not encrypted or only encrypted with WEP everything works fine. ANY suggestions?
