I am trying to hook my Dell Inspiron 1525 up to the internet with a ethernet cable however it says that it will not connect to the internet. I can connect to the internet no problem wireless and I can plug another computer into the same ethernet cable that I am trying to connect to and it works on that computer. When I hook the ethernet cable up the lights on the ethernet port on the side of the computer light up and it says that it has connected to a Unidentified Network but will not connect to the internet when I go to Internet Explorer. Thanks for the help!
