Wireless AP + Cable/DSL Router with PrintServer

Planning Your Wireless Network

A wireless LAN is a group of computers, each equipped with one Instant

Wireless

Network PC Card.

Computers in a wireless LAN must be config-

ured to share the same radio channel.

Wireless LAN configurations are appropriate for branch level departments or

SOHO operations.

The Instant Wireless

Network PC Card provides access to a wired LAN for

wireless workstations.

An integrated wireless and wired LAN is called an

Infrastructure configuration.

A group of Instant Wireless

Network PC Card

users and a Wireless AP + Cable/DSL Router compose a Basic Service Set

(BSS).

Each PC utilizing an Instant Wireless

Network PC Card in a BSS can

talk to any computer in a wired LAN infrastructure via the Wireless AP +

Cable/DSL Router.

An infrastructure configuration extends the accessibility of an Instant

Wireless

Network PC Card PC to a wired LAN, and doubles the effective

wireless transmission range for two Instant Wireless

Network PC Card PCs.

Since the Wireless AP + Cable/DSL Router is able to forward data within its

BSS, the effective transmission range in an infrastructure LAN is doubled.

The use of a unique ID in a BSS is essential.

All PCs using an Instant

Wireless

Network PC Card configured without roaming options in an inde-

pendent BSS must be configured with a BSS ID used in the BSS.

The Wireless LAN Infrastructure configuration is appropriate for enterprise-

scale wireless access to a central database, or as a wireless application for

mobile users.

Series

Infrastructure mode also supports roaming capabilities for mobile users.

than one BSS can be configured as an Extended Service Set (ESS).

This con-

tinuous network allows users to roam freely within an ESS.

All PCs using an

Instant Wireless

Network PC Card within one ESS must be configured with

the same ESS ID and use the same radio channel.

Before enabling an ESS with roaming capability, choosing a feasible radio

channel and optimum position of the Wireless AP + Cable/DSL Routers is rec-

ommended. Proper Wireless AP + Cable/DSL Router positioning combined

with a clear radio signal will greatly enhance performance.

Connecting

the

EtherFast

Wireless AP + Cable/DSL Routerto

Your Network

Unlike a simple hub or switch, the setup of the Wireless AP + Cable/DSL

Router consists of more than simply plugging everything together. Because the

Router acts as a DHCP server for your Network, you will have to set some val-

ues within the Router, and also configure your networked PCs to accept the IP

Addresses the Router chooses to assign them.

You will need the following values from your ISP in order to install the

Wireless AP + Cable/DSL Router:

• Your broadband-configured

PC’s fixed Internet IP Address

(if applicable)

• Your broadband-configured

PC’s Computer Name and Workgroup Name

•

Your Subnet Mask

• Your Default Gateway

• Your Primary DNS IP address

Whoever installed your broadband access should have left this information

with you. If not, call your ISP and they will be able to supply you with it.

Static IP Addresses

A Static IP address is an IP address permanently assigned

to a computer in a TCP/IP network. Static IP addresses are usually assigned to

networked devices, which are consistently accessed by multiple users, such as

Server PCs, or printers. If you are using the Router to share your cable or DSL

Internet connection, contact your ISP to see if they have assigned your home or

business a Static IP address. You will need that address during the Router’s con-

figuration.

Connect an RJ-45 (network) cable to the Wireless AP + Cable/DSL

Router in either the PC or Uplink port.

The PC port is used when con-

necting the Wireless AP + Cable/DSL Router to a single PC and the Uplink

port is used when connecting to a 10/100 Network. Then, connect the other

end of the Ethernet cable to either a PC or a network device. The Wireless

AP + Cable/DSL Router will then be connected to your 10/100 Network.

Connect another RJ-45 (network) cable to the Wireless AP + Cable/DSL

Router in the WAN port.

The other end of the cable is used to connect the

Wireless AP + Cable/DSL Router to your Cable/DSL modem. Connect to

your Cable/DSL modem at this time.

Connect the AC Power Adapter to the Wireless AP + Cable/DSL

Router’s Power Socket.

Only use the power adapter supplied with the

Wireless AP + Cable/DSL Router. Use of a different adapter may result in

product damage.

Verify that the LEDs are functioning.

The Power LED should remain on,

while the Diag LED will flash and turn off right away. If the Diag LED

remains on, there is a hardware error. Refer to the Troubleshooting section

for resolution.

The Hardware Installation is complete.

For directions on connecting your printer to the Wireless AP + Cable/DSL

Router’s PrintServer, see the EtherFast Wireless AP + Cable/DSL Router

section in this user guide.

Dynamic IP Addresses

A dynamic IP address is an IP address that is automati-

cally assigned to a client station (computer, printer, etc.) in a TCP/IP network.

Dynamic IP addresses are typically assigned by a DHCP server on your

Network, which can be a computer on the network or another piece of hard-

ware, such as the Router. A dynamic IP address may change every time your

computer connects to the network.

DHCP (Dynamic Host Configuration Protocol)

DHCP automatically assigns IP

addresses to client stations logging onto a TCP/IP network. DHCP eliminates

having to manually assign permanent IP addresses to every device on your net-

work. DHCP typically runs in servers and is also found in network devices such

as Routers.

Locate an optimum location for the Wireless AP + Cable/DSL Router.

The best place for your Wireless AP + Cable/DSL Router is usually at the

center of your wireless network, with line of sight to all of your mobile sta-

tions.

Insert the Instant Wireless

Network PC Card into the slot.

With the

Network PC Card’s 68-pin connector facing the slot in the rear and the

“Network PC Card” label facing up, slide the Network PC Card completely

into the Wireless AP + Cable/DSL Router.

Note: Some ISPs—most notably some cable providers—

configure their networks so that you do not have to enter a

full Internet address into your web browser or e-mail appli-

cation to reach your home page or receive your e-mail. If

your Internet home page address is something very simple,

such as “www”, rather than “www.linksys.com”, or your e-mail server’s

address is something similar to “e-mail” or “pop3”, rather than

“pop.mail.linksys.com”, you won’t be able to properly configure the

Wireless AP + Cable/DSL Router until you determine the actual Internet

addresses of your Web and e-mail connections.

You must obtain this information prior to connecting the Wireless AP +

Cable/DSL Router to your network. You can obtain this information by con-

tacting your ISP, or turn to the Appendix to learn how to

ping

for an IP

address.
