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.

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).

just flash them all to dd-wrt ... you don't even need a jtag for the v5s anymore :)

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.

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?

but don't work, only the WZC work fine with WPA-PSK TPKI or AES.

 

I'm downloading the hyperWRT...:smileywink:

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.

 

Linksys (and a few other brands) added AES to WPA along with TKIP long before there was a final 802.11i or WPA2 - pls refer to the pre WRT54G v5 firmware version history.  It was never meant to be forward 802.11i compliant, but as an additional security feature to WPA-PSK TKIP, e.g., my Buffalo WHR-HP-G54 does not support WPA2, period but it has WPA-PSK AES.  Other brands only offer WPA-PSK TKIP.  To be 802.11i compliant, one needs to upgrade firmware to a newer version that includes WPA2 if and when they are released by the manufacturer.
