R6120 - Serial number is already registered

[rushdrummer]

I know this issues has been raised several times before, but I can't find any direct path of assistance from Netgear, so I'm posting it again here. I had to perform a hard reset on my modem and router, and now Netgear wants me to register my product before allowing me access to my wifi settings. The problem is, I get the error "Serial Number is Already Registered" when I try to register. Can anyone help me?

Thanks so much.

Please post about this here for your model router:

Are you seeing this with a web browser? Which browser are you using? 
What FW version is loaded on the router? 

Try a factory reset and setup from scratch using a wired PC and web browser pointed at 192.168.1.1

Good Luck.
