Appendix E: Windows Help
Wireless-G PrintServer
Appendix E: Windows Help
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
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.
