We were having a problem where webauth on our 4402 would quit working and we had to reboot the WLC to fix it. Just got this note from TAC: "The new code 4.2.205.0 is out and the fix for bug CSCsx07878 is in this
release." We're loading the new code now. We may not know if it worked until August since the spring semester ends tomorrow... thanks John > -----Original Message----- > From: The EDUCAUSE Wireless Issues Constituent Group Listserv > [mailto:[email protected]] On Behalf Of Lee Weers > Sent: Friday, May 15, 2009 2:21 PM > To: [email protected] > Subject: Re: [WIRELESS-LAN] DeAuthentication Floods > > Are you running controller code or WISM?
