WGB with less than 10 wired clients raised several times the error "Unable to ad wired client xx:xx:xx:xx:xx:xx. WGB xx:xx:xx:xx:xx:xx. Reached max limit of 20 wired client". We had to disable the MAC from the WGB in the WLC, then reboot the WGB and enable again the MAC in order to solve the problem.
Could this be a roaming loop problem? O rmaybe this is related to the bug CSCsu57251 (https://bst.cloudapps.cisco.com/bugsearch/bug/CSCsu57251/?referring_site=bugquickviewclick)?
