Just recently upgrade our 2 5508 controllers from 184.108.40.206 to 220.127.116.11. Since that upgrade, I have a handful (8 to 10) of wireless laptops that now refuse to associate to any access points. The thing these laptops all have in common is some variation of the Intel Wifi Link AGN cards. I have about 200 other clients out there working just fine.
I've tried everything under the sun that I can think of. Patches, drivers, the whole sh'bang.
Is there a known issue with 18.104.22.168 and these particular cards? I'm really stumped.
Sounds like CSCto93293 that we discovered and worked with TAC to diagnose. The notes talk about the 1140 but is present in all AP. 22.214.171.124 fixes
