Hi Kristjan and Brendon Sorry for not responding to your mail, but I first wanted to test it.
I think the keyword is really the timeout. As long as I configured only the following, it did never associate to my parent 003a.9929.4ad0: int dot 1 parent 1 aaaa.aaaa.aaaa ! Feb 18 10:23:23 UTC: %DOT11-4-CANT_ASSOC: Interface Dot11Radio1, cannot associate: Not specified parent (from 003a.9929.4ad0) But as soon as I enter the timeout value, it tries first aaaa.aaaa.aaaa BUT then it associates to my parent, even if it is not in the parent list: int dot 1 parent 1 aaaa.aaaa.aaaa parent timeout 5 ! Feb 18 10:25:05 UTC: %DOT11-4-UPLINK_ESTABLISHED: Interface Dot11Radio1, Associated To AP 1240WGB-1 003a.9929.4ad0 [None] Great work guys, thanks! As an addition to Kristjans statement: > So this timer must be longer by default. I think it will never work without the timeout parameter.
