Firewall blocking netbios (udp/137)

bimmerdriver
The top of the list by source of packets being dropped by the firewall is netbios (udp/137) packets from my wireless AP. There are on the order of 4000 - 5000 packets being dropped per day. I'd like to find out what is causing these packets to be dropped, whether there is actually a problem or a rule that is incorrect. 

Has anyone encountered this or does anyone have a suggestion how to determine what is causing it?
