Hi,

I am not certain what you are expecting to light up on the extender's port? (as per my knowledge, only up to hardware version V3 should the RE450 have Ethernet indicator LEDs, but not the V4 model)

I suggest you try the following before ultimately deeming your RE450 to be faulty.

1) reset the RE450 to factory defaults, to be sure it is in a clean state
2) ensure the network card of your PC is configured to obtain an IP address automatically
3) connect the Ethernet cable between the RE450 and your PC
4) open a web browser on the PC and enter the address http://192.168.0.254 into the address bar

If the admin webpage doesn't open, then the Ethernet port of the RE450 might indeed be faulty.
 

  @woozle Yeah, I don't think it's working. Factory reset multiple times. Cannot get an ethernet connection at all. I'll file for a replacement.

  @GamIngDoge Also, admin page did not respond.
