|Check your Device Manager and see if your network interface is listed there. If it is, does it have an exclamation mark beside it? If it does, it's not installed properly.|
If DM lists no network interface, or there's an "unkown device" listed (and no NIC) then your NIC isn't installed properly and needs to be.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
