I have two 1410 bridges installed in a point to point link using external directional antennas. The distance between the bridges is only 200M. As you can see below from the output the RSSI and SNR are excellent with a good fade margin available. These stats are almost identical to what my path profile calculated out to be. During normal operation the latency on this link sub 2ms, during certain conditions the latency jumps to 40+ms and starts dropping packets. I say certain conditions because we have not been able to pinpoint it. Unfortunately at this time the customer does not have the ability to do any SNMP polling or collect any statistical information (working on getting this setup). There are an excessive number of data retries and am not sure if that is normal. During the issues I have observered the below command output and the numbers did not change, which leads to me believe that it is not a RF issue. It almost looks like it's serialization delay, but I have no data to back that up. During iperf performance testing of this wireless link I could push 54Mbps of UDP traffic no problem, no errors, no CRC's. Really at a loss here.

I had trouble with (I think) this exact image several years ago. The bridges were close to each other (maybe 1/2 mile), RSSI was solid, everything looked good. The bridges would not maintain association and I saw an avalanche of TKIK/MIC errors in the logs on the root bridge. The weird thing was that the bridges were working fine for a few months and then one day they weren't. We fixed the issue with an upgrade to 12.4.
Thanks for the info! I am not seeing any MIC errors at this time, but that's not to say it isn't happening. I also noticed that the image I'm running is (LD) so I'm not too excited about running it. Anyways, I will upgrade IOS and post the result.

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.
