Yes, they are all on a new switch, VLAN1, same subnet, on the PoE port.
When the AP was first configured it was connected via Ethernet. The only option to turn on Mesh that I can see is from Admin & Services/System/Mesh, other than the initial Unleashed Wizard. That enables Mesh for all the AP's. We never get to the point where we would unplug an AP because once Mesh gets enabled and the AP's reboot Unleashed does not come back up.
The ultimate plan is to have one Unleashed network with 2 R510's in office space and 3 T610's outside with one of those Meshed back to the other 2 T610's. We cannot cable one of the AP's so it has to be Mesh.
