Hey today suddenly for no reason that i know of, my internet now has no security so anyone can access my internet point! i have gone on http://192.168.1.1/ and done the admin password and gone on it. and when i try and enable the security again it just says "This web page is not available. The web page at null might be temporarily down or it may have moved permanently to a new web address." Any help would be nice. as i'm not the best at routers and stuff.
