2. In the command prompt, enter
ipconfig /all
. Then press the
Enter
key.
3. Write down the Physical Address as shown on your computer screen; it is
the MAC address for your Ethernet adapter. This will appear as a series of
letters and numbers.
The MAC address/Physical Address is what you will use for MAC address
cloning or MAC filtering.
Write down the IP Address as shown on your computer screen. The exam-
ple in Figure E-5 shows the IP address of your Ethernet adapter as
192.168.1.100. Your computer may show something different.

Appendix E: Glossary
10BaseT
- An Ethernet standard that uses twisted wire pairs.
100BaseTX
- IEEE physical layer specification for 100 Mbps over two pairs of
Category 5 UTP or STP wire.
802.11b
- One of the IEEE standards for wireless networking hardware.
Products that adhere to a specific IEEE standard will work with each other,
even if they are manufactured by different companies. The 802.11b standard
specifies a maximum data transfer rate of 11Mbps, an operating frequency of
2.4GHz, and WEP encryption for security. 802.11b networks are also referred
to as Wi-Fi networks.
802.1g
- A proposed, but as yet unratified extension of the IEEE 802.11 stan-
dard for wireless networking hardware. The draft 802.11g specifications used
by Linksys specify a maximum data transfer rate of 54Mbps using OFDM
modulation, an operating frequency of 2.4GHz, backward compatibility with
IEEE 802.11b devices, and WEP encryption for security.
Adapter -
Printed circuit board that plugs into a PC to add to capabilities or
connectivity to a PC. In a networked environment, a network interface card
(NIC) is the typical adapter that allows the PC or server to connect to the
intranet and/or Internet.
Ad-hoc Network
- An ad-hoc network is a group of computers, each with a
wireless adapter, connected as an independent 802.11 wireless LAN. Ad-hoc
wireless computers operate on a peer-to-peer basis, communicating directly
with each other without the use of an access point. Ad-hoc mode is also
referred to as an Independent Basic Service Set (IBSS) or as peer-to-peer
mode, and is useful at a departmental scale or SOHO operation.
Automatic Fall-back
- A feature provided by some wireless products to
increase connection reliability. Automatic fall-back enables a device to dynam-
ically shift between various data transfer rates. It works by decreasing the data
transfer rate when interference increases, distance increases, and other factors
undermine signal strength and quality.
Auto-MDI/MDIX
- On a network hub or switch, an auto-MDI/MDIX port
automatically senses if it needs to act as a MDI or MDIX port. The auto-
MDI/MDIX capability eliminates the need for crossover cables.

: The MAC address is also called the Physical
Address.
