I did a capture with wireshark on the port where our 3500 AP is connected and I have a ton of errors for the CAPWAP header.
The "Expert Info" Message is (Warn/Malformed): Wrong Calculate length (11) =! header lenght (15) ! (May be try to use Cisco Wireless Controller Support Preference ?)
I did a capture at the end of the day when I was the only one in the office (PC, iPhone, a couple of iPads) and I did it during the middle of the day with a good number of clients connected a lot more Apple products. It seems to have a lot more of those errors with apple devices. In fact, that is how I fist noticed it. I was trying to trouble shoot an AP that was dropping apple products.
Has anyone here encountered this problem and if so do you have a fix?
