Can't connect or see OC200
I have today got a OC200, it's the first one I have had and after plugging it into a switch and power by USB port on the back of the device. It is not getting a DHCP IP and it's also not falling back onto 192.168.0.253 until I reset it. When I reset it only the recovery mode shows so I have upgraded the firmware from the tplink website. Still the same and again, get to the recovery screen. This screen only has two other options of reboot and factory reset. Tried both and still not working.
Have I got a bad device or is there another way?
