I have some 1242 AP's set up with Cisco Fast roaming. My 3945 clients roam fine, but after a few seconds, they lose their IP address. If I have a constant ping going, my ping will drop for about 3 seconds, then replys will go for about 4 seconds. It will continue to do this about three times until stabilizing and then it works great until roaming again. Anyone have any ideas? TAC blames Intel. Intel says to work with Dell. Dell has no clue. Any help would be appreciated.
Just curios, did you check the log on the APs to verify that a fast roam did occur when it drops? I had it working just fine with my Intel 2915 cards, but have not tested it with the newer ones. I ended up turning it off because the application I wanted to use it with had nics which no not support it.
