Over the past week my Internet has been dropping out after half an hour to an hour of being connected. I can't access any websites on either Internet Explorer or Firefox but MSN and downloads still continue to work. When I restart my computer it is connected to the Internet again but as this has to be done so frequently it gets very annoying. I am running Vista but have never had these problems before. The other computers in my house are working fine and even my brother's laptop isn't having these issues even though it's the same model as mine. Does anyone have any ideas of what the problem is and how I could fix it? Thanks in advance.
