One or two years ago I replaced my EAP610-Outdoor with an EAP625-Outdoor HD as the central node for the Mesh network in our farm because of it external antennas.

As the mesh neworks increased and due to the 4 slave limit I've added a few bridges, but this 625 is still the central node in the Mesh with slave devices up to 4 hops away.

I've been upgrading FW of the devices in my network and noticed one of the EAP610-Outdoor didn't list the 625 as an available uplink. This usually happens after power outages or FW updates  when self-healing connects too many devices to one AP, but the 625 isn't showing ANY downlink mesh devices.

I verified other EAP610-Outdoor and EAP225-Outdoor APs and now NONE of them is showing the 625 as an available uplink. Reboot of the 625, OC300 controller and 610/225 Outdoor APs that formely connected to it hasn't fixed the issue.

My network topology is currently a mess, as the whole mesh network has been multihop routed through lesser signal and higher hops APs.

It is connected to an SG2005P-PD which is in turn connected to a 90W XMPP omada PoE switch port, with SG2005 reporting only 13.3 of 64 W being used, so PoE power input is not the issue.

It does show clients every now and then, so it is working.

Has the EAP625-Outdoor HD firmware 1.6.7 somehow disabled its Mesh capabilities? Has an option been introduced to do so?

what else can I try?
