Alright, looks like you are using Auto Everything and there is a problem with it trying to change the channel it is using.
I could try going to a later firmware and see if that helps you out, but I personally prefer to set my channels manually. If you don’t want to try out a different firmware, or the firmware doesn’t help for your environment, I would try hard setting your channel. Then there will not be channel change issue. That said, keep in mind if you use a DFS frequency then there will be a down time when beginning to use that channel and there is the possibility of getting “DFS Hits” which will cause the AP to change the channel automatically.
Here is a good page from Mimosa’s support manual that talks about getting a good reliable link.
