4 Frequently Asked Questions (FAQ)

4.1 What and how to find my PC's IP and MAC address?

IP address is the identifier for a computer or device on a TCP/IP network.

Networks using the TCP/IP protocol route messages based on the IP address of

the destination. The format of an IP address is a 32-bit numeric address written

as four numbers separated by periods. Each number can be zero to 255. For

example, 191.168.1.254 could be an IP address.

The MAC (Media Access Control) address is your computer's unique hardware

number. (On an Ethernet LAN, it's the same as your Ethernet address.) When

you're connected to the Internet from your computer (or host as the Internet

protocol thinks of it), a correspondence table relates your IP address to your

computer's physical (MAC) address on the LAN.

To find your PC's IP and MAC address,

Open the Command program in the Microsoft Windows.

Type in ipconfig /all then press the Enter button.

Your PC's IP address is the one entitled IP Address and your PC's MAC

address is the one entitled Physical Address.

A wireless LAN (WLAN) is a network that allows access to Internet without the

need for any wired connections to the user's machine.

ISM stands for Industrial, Scientific and Medical; radio frequency bands that the

Federal Communications Commission (FCC) authorized for wireless LANs. The

ISM bands are located at 915 +/- 13 MHz, 2450 +/- 50 MHz and 5800 +/- 75

MHz.

The 802.11 standard define two modes: infrastructure mode and ad hoc mode. In

infrastructure mode, the wireless network consists of at least one access point

connected to the wired network infrastructure and a set of wireless end stations.

This configuration is called a Basic Service Set (BSS). An Extended Service Set

(ESS) is a set of two or more BSSs forming a single subnetwork. Since most

corporate WLANs require access to the wired LAN for services (file servers,

printers, Internet links) they will operate in infrastructure mode.
