Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter
Windows 98 or Me Instructions
Wireless-G Broadband Router
Appendix D: 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 98 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 field, enter cmd. Press the Enter key or click the OK button.
2. At the command prompt, enter ipconfig /all. Then press the Enter key.
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.

Appendix E: SNMP Functions
Wireless-G VPN Broadband Router
Appendix E: SNMP Functions
SNMP (Simple Network Management Protocol) is a widely-used network monitoring and control protocol. Data is
passed from a SNMP agent, such as the VPN Router, to the workstation console used to oversee the network.
The Router then returns information contained in a MIB (Management Information Base), which is a data
structure that defines what is obtainable from the device and what can be controlled (turned off, on, etc.).
SNMP functions, such as statistics, configuration, and device information, are not available without third-party
Management Software. The Router is compatible with all HP Openview compliant software.
85
Appendix F: Upgrading Firmware
Wireless-G VPN Broadband Router
Appendix F: Upgrading Firmware
The Router's firmware is upgraded through the Web-Utility's Firmware Upgrade tab from the Administration tab.
Follow these instructions:
1. Click the Browse button to find the firmware upgrade file that you downloaded from the Linksys website and
then extracted.
2. Double-click the firmware file you downloaded and extracted. Click the Upgrade button, and follow the
instructions there.

Appendix G: Windows Help
Wireless-G VPN Broadband Router
Appendix G: Windows Help
All 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 Access Point, 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.
