Wireless-G Ethernet Bridge

Appendix C: Upgrading Firmware

You can use the Bridge’s Web-based Utility to upgrade the firmware; however, firmware should be upgraded

ONLY if you experience problems with the Bridge.

To upgrade the Bridge’s firmware, follow these instructions:

1.

Download the Bridge’s firmware upgrade file from the Linksys website, www.linksys.com.

2.

Extract the file on your computer.

3.

Open the Bridge’s Web-based Utility, and click the

Help

tab.

4.

On the

Help

screen, click the

Firmware Upgrade

button.

5.

The screen shown in Figure C-1 will appear. In the field provided, enter the name of the extracted firmware

upgrade file, or click the

Browse

button to find this file.

6.

After you have selected the appropriate file, click the

Upgrade

button, and follow the on-screen instructions.

NOTE:

If you upgrade the Bridge’s firmware, you

may lose its configuration settings.

Appendix D: Windows Help

Wireless-G Ethernet Bridge

Appendix D: Windows Help

Almost all 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 Bridge, 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.

to accept the data.

Cable Modem

- A device that connects a computer to the cable television network, which in turn connects to the

Internet.

CSMA/CA

(Carrier Sense Multiple Access/Collision Avoidance) - A method of data transfer that is used to prevent

data loss in a network.
