Nighthawk x6s EX3000/ac3000 is junk

This unit worked ok for about 5 months now. While on the network out in the shop for 4 of the 5 months I would constantly get "reconnected to network" flashing on my screens. A few days ago I walked out there and all 8 lights are blinking white, and the light next to the power button is flashing green at twice the pace of the eight front lights. Tried a factory reset to no avail. Tried the three methods of the tftp update, still nothing. Still waiting on that call back from tech support, or even an e-mail, and I'm sure all I will get is "Try unplugging it for thirty seconds...". Don't you think that is the first thing I tried to do? When I plug it in ethernet, I can not even get an IP address for it, as all three PC's can not even see it. This is my last hail mary before buying another brand. Let me know, thanks.
