Updated/restarted now power light blinks and won't work.

[NateV]

I updated my router firmware for the first time and once it restarted it only came back on with a blinking power light. I tried restarting and even turning off the power but nothing has changed.

blinking power lights tends to indicate a corrupt firmware issue. 

What you can start with is a factory reset. While powered on, push and hold reset for 7-15 seconds. If that doesn't work, then move onto recovering via tftp or nmrpflash. 

are you on windows? if so, follow this guide
