An internet connection can become slow or stop working due to a number of reasons depending on the type of the connection. Many of the problems can be solved by making software changes or small hardware corrections.

Internet Explorer, Internet Options, Connections Tab, LAN Settings, tick Automatically Detect Settings.
This could be several things.





Easiest: If this is a work network, you may need to enter a proxy server in Internet Explorer. Check the working computer by going into IE and going to Tools %26gt; Internet Options %26gt; Connections %26gt; LAN Settings. Make sure both computer have the same setting.





Harder: if this is a home network, do you use DSL? do you use cable? Perhaps your PC has software on it to dial into the DSL. Maybe your cable internet requires software as well?
