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?.

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.

Hi Thnk's for all
The Linksys its a WRT54G v2.0 firm Alchemy 1.0 final and don't have WPA2,
But after install Windows XP Hot fix KB893357
work fine with WPA (AES or TKIP) with the Windows Zero Config, (the soft of Intel don't work with WPA-PSK).

A few moments googling reveal that WPA implements a subset of 802.11i. AES is part of the full 802.11i spec, implemented as WPA2. So WPA-AES implementations might cause interoperability problems because they're not guaranteed compliant with 802.11i. How fascinating, eh?

Hmmm.... We're on the same version PRO/Wireless, but mine works with both TKIP and AES (either WPA or WPA2). In fact, my network is currently implementing WPA-PSK AES because my new Buffalo router doesn't support WPA2.
Do remember to perform a hard reset before and after you switch to HyperWRT: http://linksys.custhelp.com/cgi-bin/linksys.cfg/php/enduser/std_adp.php?p_faqid=602
Some even recommend flashing to factory firmware before switching to another custom firmware, but I didn't when I switched from Sveasoft to HyperWRT :smileytongue:

Not, but it looks like you are confusing the issue. WPA-PSK AES is not WPA2-PSK AES.

..... I think that's what I meant.... different manufacturers went with their own WPA-AES implementations, which may or may not be compatible with 802.11i. But you've made it very clear, anyway, so many thanks!
