Appendix D: Windows Help
Wireless-G Router for 3G/UMTS Broadband
Appendix D: Windows Help
Almost Linksys wireless products require Microsoft Windows. Windows is the most used operating system in the
world and comes with many features that help make networking easier. These features can be accessed through
Windows Help and are described in this appendix.
TCP/IP
Before a computer can communicate with the Router, TCP/IP must be enabled. TCP/IP is a set of instructions, or
protocol, all PCs follow to communicate over a network. This is true for wireless networks as well. Your PCs will
not be able to utilize wireless networking without having TCP/IP enabled. Windows Help provides complete
instructions on enabling TCP/IP.
Shared Resources
If you wish to share printers, folder, or files over your network, Windows Help provides complete instructions on
utilizing shared resources.
Network Neighborhood/My Network Places
Other PCs on your network will appear under Network Neighborhood or My Network Places (depending upon the
version of Windows you're running). Windows Help provides complete instructions on adding PCs to your
network.

Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter
Windows 98SE or Me Instructions
Wireless-G Router for 3G/UMTS Broadband
Appendix E: Finding the MAC Address and IP Address for
Your Ethernet Adapter
This section describes how to find the MAC address for your computer’s Ethernet adapter so you can use the MAC
filtering and/or MAC address cloning feature of the Router. You can also find the IP address of your computer’s
Ethernet adapter. This IP address is used for the Router’s filtering, forwarding, and/or DMZ features. Follow the
steps in this appendix to find the adapter’s MAC or IP address in Windows 98, Me, 2000, or XP.
Windows 98SE or Me Instructions
1.
Click
Start
and
Run
. In the
Open
field, enter
winipcfg
. Then press the
Enter
key or the
OK
button.
2.
When the
IP Configuration
screen appears, select the Ethernet adapter you have connected to the Router via a
CAT 5 Ethernet network cable. See Figure E-1.
3.
Write down the Adapter Address as shown on your computer screen (see Figure E-2). This is the MAC address
for your Ethernet adapter and is shown as a series of numbers and letters.
The MAC address/Adapter Address is what you will use for MAC address cloning or MAC filtering.
The example in Figure E-3 shows the Ethernet adapter’s IP address as 192.168.1.100. Your computer may
show something different.
Windows 2000 or XP Instructions
1.
Click
Start
and
Run
. In the
Open

3.
Write down the Physical Address as shown on your computer screen (Figure E-3); it is the MAC address for
your Ethernet adapter. This appears as a series of numbers and letters.
The MAC address/Physical Address is what you will use for MAC address cloning or MAC filtering.
The example in Figure E-3 shows the Ethernet adapter’s IP address as 192.168.1.100. Your computer may
show something different.
For the Router’s Web-based Utility
For MAC filtering, enter the 12-digit MAC address in this format, XXXXXXXXXXXX, WITHOUT the hyphens. See
Figure E-4.
For MAC address cloning, enter the 12-digit MAC address in the
User Defined Entry
fields provided, two digits per
field. See Figure E-5.
