(Security) How do I prevent remote login to Technicolor TG582n?

[#1]

If I browse to my public (static) IP address I can remotely see the login screen for my Technicolor TG582n router.
Does anyone know how to disable this so its not possible to remotely access the login screen for security purposes?
I already have Remote Assistance turned off so its not this.
Thanks all!

Are you browsing from your connection
The reason for asking is that when I had that router there were numerous attempts to connect to my IP address which were blocked by the firewall

Try browsing from an external connection e.g. your place of work (if applicable).

I see the router login page if I browse to my IP via the mobile network and wifi is disabled on my phone

I don't know why it's accessible on yours, but you may be able to get the idea of what telnet commands you need to enter to change it from this page: http://npr.me.uk/remote.html

go to some other location and try to navigate to your ip address (local library for instance) or use your mobile in somewhere like the local weatherspoons /mcdonalds (free wifi) its possible your device is recognised by the router and offers login options,
if you cant find the option to disable remote login or if changing the settting on the GUI does nothing to change the setting then you probably need a firmware reset (push the button) if after a full factory restore you have the same problem, toss the router and buy something else/
