Oh, I meant a physical power cycle, not necessarily a factory reset (which is done with a paperclip thru a little hole by the Eth ports). The APs should look on the local LAN for other Unleashed APs already running a network, and if they had been Mesh APs, when they don't find one on the Eth, they then look over the air.
Thanks Michael. Yes I am sure they have network connection. The only option for theses WAPs in the web interface is ‘remove’. I am hoping that if I select this then I will be able to add the WAP again? Just trying to get some reassurance that this is the best way to do this?
