Login issues with Netgear FS728TS

I have inherited a system which includes a Netgear FS728TS. I have loaded the discovery tool and found it's IP address.

When I start - run - http://192.168.1.6 (IP address of the router), I get a login screen. The MAC displayed is the same as the MAC sticker on the router, so I'm sure I'm there.

On the login screen, I use the default password which is password.

I get a screen with the blue banner on the left and white space in the remaining 2/3 of the screen.

The only option on the blue banner is Logout, the white space is clear.

There should be menu options on the blue baner, and configuration data in the white space.

Any ideas of why I'm not seeing that.

BTW, if I use any other password other than the default, it let's me know that the password is incorrect.
