Nighthawk AC1750 not working + erratic blinking lights

Hi everyone,

I'm hoping somebody can help me. The other day, for no apparent reason, my router started to display the erratic pattern of lights you see in the video (it's inconsistent though, sometimes its faster or slower, and sometimes other lights will turn on) and stopped transmitting. I looked online but couldn't find anything specifically on this. I've tried resetting the router, plugging it into different electric outlets, uploading firmware using Windows TFTP (it just says 'connect request failed') but nothing has helped. I wonder if anyone else has seen this or might know what's going on, it would be great if I could somehow fix it. Thanks for your time!

Re: Nighthawk AC1750 not working + erratic blinking lights

many things can go wrong when running tftp. Its why I post a guide, the video, and how to activate tftp. you can also try nmrpflash. 

are you on windows? if so, follow this guide

just make sure you enable tftp

and here's a video walk through.

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

Thank you for the suggestion. I made sure I enabled tftp, initially I hadn't and Windows said the command wasn't understood (basically). I think I'll test the nmrpflash method, but I'll check the youtube video just in case.

I am experiencing a similar problem, does anyone have a solution for that?

Re: Nighthawk AC1750 not working + erratic blinking lights

Hi roe97. I'm sorry to say that for me nothing worked and my router is basically dead. I tried both flashing methods suggested by @plemans but neither worked. Even after going through the TFTP tutorials the router kept failing to connect. I then tried the nmrpflash method and it seemed to work. But every time it would run, at some point during the process the router would disconnect. So it would never complete the process. As best as I could tell the router was failing at different times in the process, so I suspect something is going wrong at the hardware level. If you end up solving the issue I'd love to hear from you, it was frustrating to have it die just two years after I bought it.
