[all are 350-series devices on 12.01T1]
I have a (client) bridge at a remote site picking up a signal from the (root) bridge on channel 2. At the same site where I have the (client) bridge I also have an access point transmitting on channel 10. Both the (client) bridge and the access point are using a Cisco Yagi antenna (one for each, primary/right send/receive only) mounted on the same mast about two feet apart from each other pointing away from each other at about a 30 degree angle.
According to the log, the access point tries to latch on to the (client) bridge even though it is on a totally different frequency:

At the same time, the (client) bridge reports occasionanally losing its connectivity to the parent (root) bridge - probably due to the fact that we have only eye-balled the antenna orientation so far:

In any case, however, I assumed that the access point would never "see" the bridges due to its different operating frequency. I am afraid that this interference is cause for bandwidth degradation and/or the association problems reported by the (client) bridge.
Thanks for any hints how to solve this problem!

Hi ,
Do you have different SSID on AP than on the root bridge ?
Also to avoid this happening you can put mac address filter on root bridge
