I haven't read all the items in this chain so forgive me if this has already been suggested or doesn't apply to your particular auth error. We were having issues with radius authentication and 8021X over wireless awhile back until I made one change on the IAS server (Framed-MTU 1344). The specific issue we were having was related to PEAP/MSCHAPv2 and/orcertificates getting fragmented and probably parts getting dropped through the wireless tunnel even with valid authentication from IAS.

We've increased the timeouts for radius response to 7 seconds which helped some. We are using IAS for radius and disabling the full sending of trusted root certificates from the radius server. It tremendously cut down the volume of information that the radius request needs to send and made everything much faster however we do still see that error periodically. we are not seeing the specific problem however. It's described as 'workaround method 3' in the following KB article. Not sure if similar procedures are available for other radius servers. http://support.microsoft.com/kb/933430 ------------------------------ James Shuttlesworth Network Technologies Manager Ursinus College Information Technology [email protected] -----Original Message----- From: Michael Muller [mailto:[email protected]] Sent: Monday, June 04, 2012 1:59 PM To: Enterasys Customer Mailing List Subject: Re: [enterasys] Dell disconnect from Hipath AP 2610 Interesting, does anyone of you also have messages like that one below? 06/04/12 14:23:37 Critical Radius Client Radius server available for WLAN service : 8021x. 06/04/12 14:22:48 Critical Radius Client No radius server available for WLAN service : 8021x Client [74:e1:b6:ad:10:06].
