Intel PRO/Wireless 2200BG fine with WEP, bad with WPA

I have a Latitud X1 with Intel PRO/Wireless 2200B.
 
I tested with a 2 wifi-router Linksys and SMC Barricade.
 
The Intel PRO/Wireless 2200B work fine in both routers without encryption or with WEP encryption (64 or 128 bits).
 
But no work with WPA (Pre-Shared Key) encryption (AES or TKIP Algorithims).
 
The routers work fine with others wifi-cards in WPA mode.
 
The Wireless SSID Broadcast its Enable.
 
I'm using Windows-XP Pro SP2 with the last soft/drivers of Intel 2200B, and the problem its the same using the Windows for management WI-FI or using the soft of the Intel.
 
Any idea for use the WPA?.

Re: Intel PRO/Wireless 2200BG fine with WEP, bad with WPA

Since you mention AES and TKIP, I guess you're trying to set up WPA2.  This will work perfectly with the 2200BG, but WPA2 does require an update to XP. This hotfix is not offered automatically on Windows Update, so you will need to check that it is installed.

Go to Control Panel | Add or Remove Programs. Make sure that "Show Updates" is checked, and look for

Windows XP Hot fix KB893357

If it's not installed, you can download it from here: http://support.microsoft.com/?id=893357

Once you've rebooted, you should find that there is an option for WPA2-PSK when you try and set up your connection. Personally, I find that the Windows Zero Config works better than the Intel Pro/Wireless software -- it certainly uses less RAM.

Hope that helps.

Linksys has been implementing TKIP and AES under WPA long before there was WPA2, and the WPA2 update is not required if Intel PRO/Wireless client is in use.

..... Well, I didn't manage to get it working even with Pro/Wireless until after I'd installed the hotfix, but that could just be my ineptitude.  So perhaps I should have said that in my experience, the Intel 2200BG card simply wouldn't connect to my WRT54G v5 using AES without WPA2 (802.11i, I believe).  TKIP was OK, but then as I understand it, it's WPA as well as WPA2.

My 2200BG will connect to my Linksys WRT54G v1.0, WRT54G v3.1 and Buffalo WHR-HP-G54 on WPA-AES alone - there is no need for WPA2, but it will also connect on WPA2-AES as well if needed.  The WRT54G v5 is not a good basis for comparison - too many unresolved issues with this router.
