I have a problem with the Aironet BR350, in the way it handles diversity. I run V12.05, and I use them as bridges with clients which means other bridges can route through.
I have Tx/Rx diversity enabled on both rightand left antennae, and I log the signal strength every second via SNMP. It is my perception that the radios will keep the connection down to 30-35% signal strength.
However, some times when the Rx signal strength on a non-root unit is averaging around 60-70, a singular drop to 35-40
(or even higher like 45)
would coincide with the root unit to restart the process to the non-root-bridge, which causes a dropout of about 30 seconds. Reason for the drop of signal strenght is believed to be a short temporary multipath fade much less than 1 second, and in some of these cases the signal quality also gets worse. But I only get one outlier hit in the log. It is too bad that this causes 30s outage.
At this time I know for sure that the other antenna has a reasonable signal.
Has anyone got any similar experience, and maybe a solution?
