my roommate has an IBM thinkpad. recently, it stopped connecting to the network and consquently the internet. for one, the ethernet port is screwed up somehow, which makes it difficult to work on it because the network cable keeps disconnecting. but even when it is connected, it doesn't work right. for some reason, I can't properly set up a network connection. on the network connections page, it says the network connection is "connected". I go through the set up home or small office network and go through that and it says it's configuring the connection, and in the background on the network connection page, the network connection changes to "enabled, firewalled". you can even get on the internet and load pages while the network is configuring. but then there is some kind of error, and the setup network connection wizard stops and the conection goes back to being "connected" and no web pages will load. Any idea what would cause this?
