You can probably configure your WEP or WPA key to be your MAC address, but they are not in no means the same thing. Think of your WEP key as the password to the router, and the MAC address as... well the address/location. To get into the router (connect) you have to give the Wii (or whatever wireless device you are trying to connect to the router) the password to get access to the router and it's network.Originally Posted by SAVAGE420
EDIT: Wait, you're using the LAN adapter? If you are connecting via CAT5 (Ethernet cable) you shouldn't have to mess with any of these security settings. A device hardwired to the router should receive an IP address automatically (if the router is configured as a DHCP server) and connect by itself.
