I have two RB511 configured with WDS. The link is very intermittent and I get high packet loss although the devices have good signals levels (better than -68dbm 99% of the time) according to the registation tables. The problem seems to be worse at certain times.
Below find some detail:

Any ideas what else I can do to do more detailed troubleshooting and get to the root of the problem?
