Is the physical address the same as WEP key?
No, the physical address is different from the WEP key. The former is the unique number that is assigned by the manufacturer to the network card. All network cards — wired or wireless — have unique identification numbers. It’s like a serial number that is electronically stamped into the chipset of your network card. The physical address is also known as the MAC (Media Access Control) address. In the case of Apple computers (iBooks and PowerBooks), the physical address is also known as the Airport address. The WEP key, on the other hand, is like a password which is given to the registered users of the Loyola Schools Wireless Area Network. Without it, you won’t be able to access the WiFi network.
