I have a new Airport Extreme Dual-band 802.11n base station, and various WIFI devices. I am connecting to it from a Thinkpad W500 laptop that has an Intel 5100 AGN WIFI card and Windows XP Service Pack 3. The card is capable of 'n' mode at 300Mbps
I can connect in 802.11b and 'g' modes when using WEP or WPA-PSK. I can connect in 'n' mode at 300Mbps when I turn off security. My problem is that I can't connect in 'n' mode when I try to use WPA-PSK. My laptop either won't connect at all or will only connect in 'g' mode at 54Mbps.
Some more details:
1) I have configured the Airport Extreme to turn on both its 2.4Ghz and 5.0Ghz networks and use a different SSID for each. This permits me to try to connect directly to the 5.0Ghz. network.
2) I can see both networks from my laptop -- meaning that my laptop reports two base stations, each with one of the SSIDs.
3) I am aware that an 'n' network slows down to 'g' mode if there are any 'g' devices. But (a) I have this problem even when there are no other WIFI devices connecting to the base station; and (b) the whole point of a dual network setup is to get the 'n' mode on the 5.0Ghz network; and (c) I can connect in 'n' mode when I turn off security.
4) For the WPA-PSK, I have selected AES mode on both ends and entered the same key.
I have spent several hours on the phone with Apple support on this and another problem with no solution. So at this point, I'm quite frustrated.
