I've recently installed 140 + 1131 LWAPP AP's w/ 3 controllers in a N+1 configuration and a WCS. We're using a blue socket appliance for authentication so there is no security for the client to deal w/ when connecting to the AP, just to authenticate to the system.
The problem that I'm having is that some of our students that have PDA's can't connect to the system. Even my Dell D400 notebook can't connect now (using the intel 2200bg internal nic).
Does anyone know of a list that's available that shows what devices are known to have problems connecting w/ 1131's in LWAPP configuration?
There isn't a list of client adapters as a whole that experience incompatibilities.
However, there are a number of client adapters that didn't properly send WPA MIC frames (including the Intel 2200). You would be seeing WPA MIC validation errors in your logs and the client would be excluded for 60 seconds before being let back on the wireless network. This was corrected with a driver upgrade early 2006. So, if you are using recent drivers this shouldn't affect you. In addition, it didn't sound like you were using WPA.
I would capture a wireless trace of the clients attempting to associate. TAC can certainly assist in interpreting this.
