| i keep telling you its a wifi card not a router.|
Irrelevant! Wi-fi security is configured in the router, not the wireless card in the computer. All you can do with a wireless card is configure it to connect to a wireless router.
As I said earlier, the only people that can get to see the MAC addresses you wi-fi card are those that are connected to the same Local Area Network as you are. That is someone that has the an IP address identical to yours except for the last group of digits.
