I changed my dhcp configuration to give the MSM422 a static IP address and now it is 'waiting for acceptance' by the MSM710 controller. There are two other APs that made the switch just fine. I looked in the logs and all I could find is this: AP (name='ROOM105 - CEILING') requested to be managed by controller (name='00:0F:61:09:0D:14')
What should I be looking for? thanks!
