The computer I'm using is a Dell Inspiron 1420 and I am trying to connect it to the internet using a wired connection for faster speeds. We have one computer connected so I know there is nothing wrong with my network. I have Broadband and I plugged an ethernet cord into the port in my computer but I am still not getting internet. The network doesn't come up on the "available networks" icon on the bottom right. The only thing I can think of is that I need a username and password from the ISP, but I don't know. What should I do?
