I'll admit, I'm a bit iffy on the realm thing...
I'm assuming your D-link router does HTTP Basic authentication here. To be certain of the realm, use a web-browser to visit the page, and pay attention to the dialogue box that you get. With my browser, I get the string "Please enter username and password for "Realmname"..." — this gives you the realm name you should be using.

Here's my attempt at what you might want... untested, because I don't have access to a D-Link router, and I'm a bit too lazy to set up a webserver with HTTP Basic authentication. 

#!/usr/bin/perl

use warnings;
use strict;
use LWP::UserAgent;

my $ua = LWP::UserAgent->new();
$ua->credentials("192.168.0.1","192.168.0.1","admin", "password");

my $response = $ua->get("http://192.168.0.1/st_devic.html");
        die "Error while getting ", $response->request->uri,
          " -- ", $response->status_line, "\nAborting"
         unless $response->is_success;

print $response->content, "\n";

3rd Update (yikes!): You want to use the server's location as the first argument to credentials. I missed the different IP addresses when I first read your code.

It's not easy to juggle a pregnant wife and a troubled child, but somehow I managed to fit in eight hours of TV a day.

Update: Apparently I'm confusing Latex commands with HTML entities. Sigh
