Okay, I'll try to explain this and hope it makes sense:
Our cabling vendor removed an AP93 from one location - it was already provisioned for that AP-Group. We thought the AP was flaky, but ended up being a bad termination at the patch panel. We were never given the chance to remove from that AP-Group and move back to default.
Fast forward a few weeks and he's in an office that needs another AP for coverage. He hooks up the AP, sees the appropriate lights and leaves without contacting me.
I can see the AP is on the network (can see the MAC in DHCP), but it does not register on the controller (620), although I do see the port is active.
To further complicate issues, the office controller is running 6.1.3.6, while our master controller is still running 5.0.3.3. The AP was in Airwave, but was removed while I was waiting for my additional license order to be processed.
Since the office controller is at a higher firmware than the master, I'm sure the AP has been upgraded and no longer reachable by the master.
I've had this happen once before, but that AP was still in Airwave, so I was able to change it to managed-mode and put it back in the default AP-group, the provision it properly.
What is the easiest way for me to get this AP to a point where I can reprovision it to the correct AP-Group? I'm thinking I might have to roll the office controller back to 5.0.3.3, which I believe will put it back to a role as master, but it can then be demoted to local.
Is there a better way to do it?
