Hi

We have 3 new AIR-LAP1131AG access points connecting to 4400 controller with software version 4.2.205.0. The access points connect to the controller and start downloading their software. After a few minutes the access points reboots and starts over. Below is information from the trap logs.

We recently ran into this. If you are using LAG on your WLC; make sure you have a port channel configured on your connecting switch. An easy way to see what is going on is to telnet into the WLC and enable debug "debug lwapp events enable" With this we saw an error message "packet 3 received, packet 4 expected"
