So, webpages won't load in your browser, is that it? From the sound of it, seems like you have no problem getting logged into your router and viewing the configuration screen. That at least means your physical connection is fine and Windows can see it.
Open up a command prompt (Start -> Run and type cmd). Try pinging any website by typing something like this:
ping www.yahoo.com
After hitting enter, it should return some results indicating packet loss at 0%. If any error messages appear, post back. If you do get the results fine, then most likely you have a browser problem. Let us know what you find...
