I have an installation using Cisco 1242 Access Points (IOS) as bridges
in 5Ghz band, and as AP in 2,4 GHz band. Sometimes I get problems
with the non-root bridges, after mains outage, they will not
associate to the root bridge. Command "dot11 do 1 carrier busy"
issued to the non-root bridge helps, but sometimes I have to use it
several times. Have anybody any idea about possible cause?
