I'm trying to install my this however despite being paired it cannot identify a network/"Ethernet" doesn't have a valid IP configuration/there's no Internet, and I'm not quite sure what to do. I've followed steps on Google and the support on the TP-link site, however nothing has worked.

I've tried to reset it to start over because perhaps I'd set it up wrong, and now it doesn't seem to be pairing either: the power LED on the one connected to the PC is on as well as the ethernet LED, and the one connected to the Wifi is having the power button flash every 15 seconds, and there's no change if I try pressing the power button for 1 or over 6 seconds either. 

Any solution or idea?
