I have noticed the Macs failure to get an IP even though they pass the 802.1x authentication. This problem seemed to get a lot better moving from 10.4 to 10.5 and even a little better with the latest 10.5 releases. However, when a client first authenticates after having their computer off-campus, it seems the Airport has to be toggled off and back on once or twice before the Mac receives an IP. I have been getting the information out to Mac users to toggle the Airport off and back on but the problem is very annoying.
I have not noticed any of the 11a problems mentioned. _________________ Angela K.

Wondering if anyone else is seeing Mac behavior along these lines on the latest Apple code versions including 10.5.6: Clients will associate to lesser-quality 11a cells even though better 11g signal is present (FREQUENT) Clients will stick to the 11a AP they associate with even when they have the opportunity to move to better (stronger, less users, good SNR) 11a signal (FREQUENT) Clients appear to be fine in every way- good association, good SNR and signal strength, pass 802.1x authentication, all indications are fine. Yet they have difficulty getting IP address or doing anything else despite their nearby peers having no issues at all, in cells that are not overtaxed. (LESS FREQUENT) We have about 35% Macintosh penetration among our 5-6 thousand user per day client count. But of late, every wireless client issue not easily resolved seems to be with Mac hardware doing the above described. Is any one else feeling these symptoms? -Lee Lee H.
