I have 2 Rocket M2 XW (verified as XW through AirOS prior to flashing) - initially had AirOS 6.1.5 on each unit. I downloaded the appropriate firmware (checked it 3 times prior to flashing the units) and flashed - the flash completed and the devices rebooted. Now NEITHER of the units is issuing an IP address via DHCP. Have used mulitple laptops to try and get a lease but "no go."
The units both actually start up, Green light on the left, a green network light when the cable is plugged in, and after booting, a solid green light on the right-hand side as well.
