Just installed an 1142 a couple weeks ago and since day one, the output drops incriment constantly. There is only one user connected to this AP, and it is a stand alone. I saw somewhere that it might be dropping multicast packets, but the command "dot11 igmp snooping helper" is a default command. I tried taking that out, still nothing. There are no Ethernet interface drops on the AP or the upstream 3560 switch. Below is the show interface commands for the connection. This is a trunk port with multiple networks being sent across, but like I said, there are no issues with ethernet interfaces.
