I have an issue where I recently added a new SSID to a batch of older 1200 series access points running IOS. I set the SSID to use WPA with a TKIP cipher (they can't handle AES). Our office uses all Dell laptops with the Dell internal wireless cards. Using the Dell wireless utility, the laptops can associate to the APs using the new SSID and proceed to go through the PEAP authentication process.
The problem I run into is that I can't get the built-in Windows wireless utility to associate using the new SSID on the same laptops. This is on Windows XP as well as Vista. It's not that the PEAP process is failing, because it never even gets to that stage. It's like the wireless utility doesn't see the network, or it does but doesn't think that it matches up with the profile settings. The SSID is set to not broadcast itself.
In the Widoes utility, I setup the profile with the correct SSID (ensuring proper case). I try using WPA-Enterprise and TKIP for the key/encryption settings with no success. I have even tried the other available key options with no success. I've tried checking and unchecking most every option in the profile setup.
Does anyone have any ideas as to why the Dell utility would connect to the new SSID and the built-in Windows utility will not on the same laptop?
