Hmm, I'm not familiar with that router model, so will open up your question to our other experts now. You will be automatically notified when another expert picks this up; also, you may disregard and close any remote offer if it shows up on your screen now. Thank you.
Please unplug the Nighthawk router and unplug the modem. Wait 1 minute
Plug in the modem and wait 2-3 minutes. Plug in the router and wait another 2-3 minutes.
Try connecting now.
