R7000 Sudden Death - radio lights out; ethernet ports all red/purple, can't reset, no HTTP response.

[Merlin_309]

Disappointing.  After only 4 years my Nighthawk R7000 died suddenly.  The reset button is inoperative.  I can't connect to it using an ethernet cable connected to an isolated computer.  Both the 2.4 and 5 GHz radio lights are off, and all 4 Ethernet ports light up red (more like a purple color) immediately when power is applied (no cables are attached). I'd hate to sell this for parts on E-Bay if a fix is known.  Photos attached.  Any thoughts ???

Sorry. You're probably SOL then.

You could try recoving it via tftp

are you on windows? if so, follow this guide

https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP

just make sure you enable tftp

and here's a video walk through.

and if that doesn't work, you can try using nmrpflash

Plemans:  Thanks for the suggestions, but nothing worked.

No Joy - unable to connect to the router

I also tried that.  After installing the required support program for NMRFlash, NMRFlash was unable to locate the R7000 router plugged into the ethernet port of the computer.

I appreciate all your suggestions, but I think this router is toast.

It was worth a shot. by chance to you have a spare/different power supply that you own? I wouldn't buy one but if you had a matching (same voltage and at least the same amperage) it might be worth trying. power supplies have been known to go bad.

[Merlin_309]

Good idea - - but no luck with an alternate power suppy.

Yep - - Replacement already in place.
Linksys MR8300

Hope it treats you well! I've had a couple linksys routers and they worked well for the most part
