[hectorq1]

Hello

I am using Windows 10, I was updating the firmware on  my router a R6900P Night Hawk AC1900. when a 2nd party reset and turn off the router. More then likly the Bios or firmware was corrupted. 

The question is how do I corrected, replace it or upload a new version?

what is the best version for this modem? 

Thank you for any advice or suggestions.

I'd highly recommend any firmware updates be done over a hardwired connection.

are you on windows? if so, follow this guide
