N300 Wifi Extender Device Link LED not Lighting

Hello and thanks for your help on this issue.

I have been trying to set up my N300 extender for the last hour, but I can't even get past the first step because:

1. The Device LED never turns on, and

2. Every time I try to connect to the EXT network the Power light goes Amber and the connection is lost

I did a successful Factory Reset and it did not make any difference whatsoever. I also tried connecting to the extender directly from my Mac with an ethernet cable and it made no difference (obviously because of the amber power light). I cannot access www.mywifiext.com to set up the router or even update the firmware, etc. For this reason, I am about to actually throw the extender in the garbage, unless someone has any ideas as to what can be done. I bought it years ago, so there is no getting support from Netgear without paying, which I refuse to do.

Thanks again for your help.
