Thanks this was very helpfull. I had to modify the script a little because i had a "401 authorization error" when i tried to connect. I solved the problem by adding the portnumbers after the url. 
!/usr/bin/perl --
use strict;
use warnings;
use WWW::Mechanize 1.73;
my $browser = WWW::Mechanize->new( autocheck => 1 );
$browser -> agent("Mozilla/5.0");
$browser -> credentials('192.168.1.1:80','NETGEAR WNDR3800','admin' =>
+ 'guess');
$browser -> timeout(10);
$browser->show_progress( 1 );
$browser->get('http://192.168.1.1:80');
if( $browser->success ){
   die " we logged in game over";
}
