help diagnosing 2.4 link

Hi,
I have 2.4 link that I’m using as a bridge.
It is about a 12 mile link.

The link tends to drop a couple times an hour for about 30 seconds each time.
It’s been running since last spring and just started doing this in the last few weeks.

Here are the stats:
signal strength: -61
tx signal str: -60
signal to noise: 38
tx/rx ccq% : 63/75 - this tends to move a lot, especially the tx (45-75 range)
tx/rx rate : 36mb/36mb

any suggestions are appreciated, thanks!

scan and find if there is any other radio links in the area maybe interference. which equipment are you using on your links

It seem you running on 11g.

Why you don’t use 11a? or just set it to be 11b, to get more reliable link.
