Does the system slow down when you have your internet connection enabled, but aren't explicitly using it (i.e., not using a browser)? If so, look at the netstat output (as root) to see what's going on. You may have some process that runs when the connection is enabled that is taking up system/network resources. Separately, turn off javascript in the browser you are using and see if that has an effect. - Richard
