I've been having similar issues since we upgraded from WiSM to 5760.
I have a few remote offices that have a 10M half duplex WAN link, and the AP's have a hard time joining the controller. Sometimes they will join after DAYS. The MTU size at one site is less than 1500, so I'm not sure if that is an issue since you cannot set the MTU on the 5760 to less than 1500.
I upgraded our code to 03.07.00 and now I have 3 sites where the AP's are not coming back.
The issue for me was due to capwap packet fragmentation not working. We have strict firewall rules and discovered that ICMP was required to be open as the VPN IP was trying to send a ICMP 'packet to large' message to the 5760. Once ICMP was open that fixed the capwap issue for the APs connected across the VPN.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.
