My wife's laptop running Windows Vista suddenly can't connect to the internet through the LAN cable by which she is attached to our wireless router (she doesn't have wireless facility in her computer). I've tried several cables and know they are working, the router is working since I'm getting a wireless signal from it in another part of the house. What else could be the problem? Neither Firefox nor Explorer are working, nor any other applications that use the Internet. Help please. To put it mildly, internet connections are not among my areas of expertise!!

What kind of router is it? On some routers theres an option to turn off LAN ports to save power...

Actually I solved the problem by rebooting the router. It was as simple as that!!
