Can't Connect to a Wireless network with AES encryption

Hello All,
We are testing a new wireless deyployment and I am running into some issues.  I finally got EAP-TLS authentication to work after discoverying that I had to use TKIP encryption.  I don't want TKIP I want AES encryption.  Everything has the latest drivers we have Windows XP sp2, Active Directory, CA, and IAS radius.  I can't even get the notebooks to connect to a WPA-PSK using AES any help would be greatly appreciated.  THanks

Not all devices support WPA using AES.  Are you sure that both your AP and NIC are AES capable?

Yes i am sure, We have Cisco APS and year old notebook computers

What kind of NICs are in those year old notebooks I'm suspecting they don't support AES either?
It is an HPWLAN W500, it has the latest driver and the driver states that it should work with AES.  Thanks
Three questions:
1) Do you have the wireless rollup update installed?
2) Is Windows managing the connection?
3) Just in case, do you have any other cards that support AES that you can test with?
Which wireless rollup? i would assume that I have it, yes windows is, and I think i do have another that i can test.  Thank you

However, all of this stuff is supposed to be in SP2, which I noticed you specfically mentioned having.

I'm wondering if there's something with either the card's implementation or the way software interfaces with it. Was there a utility that was on the laptop for it?

Was there a firmware update for the HP wireless cards?
I can check on HP's Site, the only thing it could be is windows, i havn't tried the Atheros utility that comes with it because that thing is garbage
I have found a few more people having the same issues as me, MS supposedly has a fix for this but it doesn't work!!!!!!!!! I would bet if I use a 3rd party supplicant it would work.  That will not work for are full roll out though because the supplicants don't work very well... Anybody get around the MS issue?
I figured it out, MS released an update that allows for WPA2 and WPA2-PSK to be added to the encryption settings on there supplicant.  THis is the name of the exe. WindowsXP-KB893357-v2-x86-ENU.exe.  Thanks all.
