My computer is a desktop running Vista and up until now I've been able to connect to the Internet through the gigabit switch (which is connected to the router) but now it can't.  However, when I plug the computer directly into the router (through the wall socket into the router) the Internet works fine.  When try the diagnose and repair the problem it says, "There might be a problem with one or more network adapters on this computer" and there are some options to choose (none of which resolve the problem):
1) Plug a cable into the network adapter "Local Area Connection* 12"
2) Automatically get NEW IP settings for the network adapter "Local Area Connection"
3) A problem with your network router or broadband modern might be preventing an Internet connection
4) Reset the network adapter "Local Area Connection" (replaces OPTION 2 after I click it and it tries to repair)
Again, none of those options work...but they COULD be of help to you...

What should I do to fix that?Could you provide a little more info?  If you load the command prompt (click start-->run, type "cmd", hit ENTER) and enter "IPCONFIG /all" you'll get a screen full of information.  Could you cut and paste that in here, please?
