Appendix C: Windows Help

Appendix C: Windows Help

Almost all Linksys 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 a network 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.
