Thanks. I got it to work.
I tired to open the page in Koqueror web browser and got this message:
Authorization Dialog
====================
You need to supply a username and password to access this site.
Site: WRT54G at nnn.nnn.n.n
I tried useing "Authorizaiton Dialog" with no success. So I tried opening
the same page with lynx with the trace option on. I found that lynx used
WRT54G as the realm, so I tried it and it worked.

So I just make a file called /etc/router_passwords and include
something like
WRT54G username password
Then parse the file, and supply the info to the password handler? This
is easy to do, and I guess it is secure. I am networking on a home
system, so security is not so big a concern. However, I have seen a lot
of people struggle with getting router addresses from the WRT54G,so I
thought I might offer my script, and I wanted to do things a secure,
normal way.
Thanks
