unable to login to the web interface of my Nighthawk 5400

Any progress on this? 

Did the factory reset work? This fixes this issue on this version of FW:

Rebooted the Arris SB8200 modem, and the nighthawk router, waited for both to come back up, and tried again with unfortunately the same error:

"Access to the requested page has been denied."

and a URL with a serial number that does not match my device:

https://accounts-qa.netgear.com/error?redirectUrl=http:%2F%2F192.168.1.1%2Fgenie_redirect_SSO.htm&serial_num=5G018A7EA006B

 

I went over to the my netgear page and noticed my router wasnt listed, which I could have sworn I registered when I bought it, because from the mobile app it says device registered, but when I attempted to add it to the my netgear page it says my serial # is registered to someone else?

 

Sent an email to netgear support, but no response so far.

 

I guess my last resort is going to be a factory reset to see if that resolves the issue
