You should still be able to log in manually to the router to update it.
How do I manually update the firmware on my NETGEAR router? | Answer | NETGEAR Support
Step 8 : Enter the router admin user name and password.
The default user name is admin. The password is the one you specified the first time you logged in. The user name and password are case-sensitive.
Already set up and don't have the information to log on.
Will try fixing the double NAT once the router is updated

Already set up and don't have the information to log on.-----That's why I'd say factory reset. it gets you back to the defaults so you can log in and change them. Then update.
