802.1x wireless problems

Question

With 802.1x authentication using true mobile wireless card  (1300,1350,1400,1450) using G, I have troubles getting back IP addresses.  I do suceed authentication but do not get an IP. I am on the most recent drivers of the True Mobile. If I switch the IBSS mode to (802 b only) or set the rate to (11) I do get an IP back.  I seem to have troubles getting back an IP with G particularly.  I do get back IP addresses using other wireless cards on G (Dlink,Cisco,Broadcom,Intel,Linksys) but have a lot of trouble with True Mobiles.  Any suggestions?   Access Point -Here is what we are using Cisco 1200 on  IOS on 12.2(13)JA  Radius Sever - Steel Belted Radius 4.71 Authentication - Peap Authentication with active directory

If it hurts when you do that, don't do that.  It has been long advised on these forums to uncheck 802.1x Authentication.

What is it and what does it do? What does unchecking it do?

It is a negotiation standard that was poorly implemented across manufacturers.  I believe it only works correctly if you have WPA working properly.  It isn't needed otherwise.

802.1x  is a standard that was implemented for security so I thought.  If I uncheck 802.1x I am guarenteed to fail authentication.  I do not believe this to be an 802.1x isssue since if I switch the True Mobiles to use just B they work fine.  I believe the issue here is how true mobiles change between B/G/A
