Why does this happen to Linksys while trying to port forward?

So for minecraft, I am trying to get my friends on my server. I read that you have to use port forwarding and a static IP. The Minecraft wiki suggested to go here http://portforward.com/english/routers/port_forwarding/Linksys/WRT54G/Minecraft_Server.htm
(I have a Linkys WRT54G router)
I then went to the Static IP Address Guide to set up a static IP.
http://portforward.com/english/routers/port_forwarding/Linksys/WRT54G/Minecraft_Server.htm
(I have Windows 7)
Everything on that page went well. So I went to the previous page, as it instructed to do so.
I put the internal IP (192.168.1.1) into the address bar and then entered the username (blank) and password (admin.)
Heres where it went wrong.
If you look at the webpage, it shows a screenshot of the Linksys thats supposed to show up, but this is what shows up for me

Not everything shows up, and what does show up is in Italian. Ive tried this several times, and this is all I get.

How do I fix this?
