Cheers,

I've got a bit of a "probably holding this wrong" question, but I haven't been able to find useful hints while searching.

I'm using a fully mesh setup here, three APs with no wires between the lot of them.

AP A has a little network island containing the software controller.

AP B has the Internet gateway (FritzBox) for the LAN.

AP C is just slightly boring overall.

I just now changed AP from being wired with a separate PSU to being powered by PoE.

Since plugging it back in (lights are on, yeah), the AP doesn't want to jump back on the Mesh. The controller just shows it being disconnected, and even when waiting for ten minutes, there's no change to be had.

So, why is the AP not coming back on the Mesh? It'd kind of defeat the purpose of a mesh if I'd have to run a wire over there for provisioning...
