|You need to know what your make/model your network interface is in order to download the correct drivers for it.|
If it's a brand name PC (ie: Dell, HP, Compaq etc) find the model number of the unit and go to the manufacturers website and find the downloads for your model. You'll find the NIC (network interface) drivers there.
If it's a custom build and fairly recent, your NIC will be built onto the motherboard. The motherboard manual will list the NIC info. If you don't have the manual, look up the specs for your motherboard and that will list it.
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.
