It was actually autmatically configured
Thank you to every one that helped with ma problem, the card isn't actually fucked up, the computer had automatically configured and installed the card without it even showing up on the screen, maybe thats why it couldn't even detect it cause it had been installed. so to anyone else that may have my problem, check your device manager properly.
I have another problem though, my network is working OK, but only one computer can access the resource from the other, one of them can't access files on the other one, it asks for username and password whereas i didn't put any username or password on it when i created the network. i am wondering whether i have created a Client-Server based network accidentally.
how can i create a Peer to Peer network, so both computers can access each other's files and data.
