We have the follow situation :
Host -- ethernet --> AP1 (with wirelessClients) < --- > BR1 (BR1310) (with wirelessClients) -- ethernet-- AP5 with wirelessClients
< --- > BR2 (BR1310) -- ethernet-- AP6 with wirelessClients
AP1 was untill may 2010 a AP1200(with VXworks OperatingSystem )
Till then, there were no problems.
Then we changed AP1 with a AP1240G ( autonomous, newest IOS).
Configured it as Root Brigde with clients.
When a client is working between AP1 and BR1310 we get the following error on AP1
Bridge loop detected between WGB 0012.xxxx.yyyy and device 0018.bbbb.aaaa
and the clients connected to AP5 haven't connection to the Host.
But the BR2 -side is working without problem.
Thank's for help.
