Wireless Ethernet Bridge

If the wireless network is relatively

small and needs to share resources

only with the other computers on the

wireless network, then the

Ad-Hoc

mode can be used.

Ad-Hoc mode

allows computers equipped with

wireless transmitters and receivers to

communicate directly with each

other, eliminating the need for an

access point.

The drawback of this

mode is that in Ad-Hoc mode, wire-

less-equipped computers are not able

to communicate with computers on a

wired network.

And, of course, com-

munication between the wireless-equipped computers is limited by the distance and

interference directly between them.

Figure 3-2 shows a typical scenario of four Wireless Ethernet Bridges in ad-hoc

mode. Figure 3-3 shows a typical wireless bridging scenario using two Wireless

Ethernet Bridges. Each wireless network is connected to a Wireless Ethernet

Bridge through a switch. A separate notebook computer is equipped with a

wireless PC card and can communicate with both wireless networks as long as

it has the same SSID and channel as both wireless networks.

Unlike wired networks, wireless networks have two different modes in which

they may be set up:

Infrastructure

and

Ad-Hoc

.

Choosing between these two

modes depends on whether or not the wireless network needs to share data or

peripherals with a wired network or not.

If the computers on the wireless network need to be accessible by a wired net-

work or need to share a peripheral, such as a printer, with the wired network

computers, the wireless network should be set up in the

Infrastructure

mode.

The basis of Infrastructure mode centers around an

access point

, which serves

as the main point of communications in a wireless network (see Figure 3-1).

Access points transmit data to PCs equipped with wireless network card, which

can

roam

within a certain radial range of the access point.

Multiple access

points can be arranged to work in succession to extend the roaming range, and

can be set up to communicate with your Ethernet hardware as well.

For security purposes, you will be asked for your user name and password

in order to access the Bridge. In lowercase letters, enter

admin

in the

Password

field (later you can change the password through the Web-Based

Utility). Click the

Yes

button to continue or the

No

button to return to the

previous screen.

The screen shown in Figure 5-5 shows a choice of two wireless modes.

Click the

Infrastructure Mode

radio button if you want your wireless

computers to network with computers on your wired network using a wire-

less access point. Click the

Ad-Hoc Mode

radio button if you want multi-

ple wireless computers to network directly with each other. Do not use the

Ad-Hoc mode if you want to network your wireless computers with com-

puters on your wired network. Click the

Back

button to return to the previous screen.

The screen shown in Figure 5-2 shows the two ways to configure the Bridge

using this Setup Wizard. Optimally, you should perform this setup through

a PC on your wired network. You can also set up the Bridge through one of

the PCs on your wireless network. Click the

Exit

button to exit the Setup Wizard.

3.

The screen shown in Figure 5-3 displays a list of Wireless Ethernet Bridges

on your network, along with the status information for each Bridge. (If you

have only one Bridge on your network, it will be the only one displayed.)

Select the

Bridge

you are currently installing by clicking its name in the

Selection box. Write down the IP address of the Wireless Ethernet Bridge,

so you can use it to access the Web-Based Utility later. Click the

Yes

but-

ton to continue or the

Exit

button to exit the Setup Wizard.

•

SSID

- The SSID is the unique name shared among all points in a wireless

network. The SSID must be identical for all points in the wireless network.

It is case-sensitive and must not exceed 32 characters (use any of the char-

acters on the keyboard). Make sure this setting is the same for all points in

your wireless network.

•

Channel

- Select the appropriate channel from the list provided to corre-

spond with your network settings, between 1 and 11 (in North America). All

points in your wireless network must use the same channel in order to func-

tion correctly.

encryption, select

64-bit

or

128-bit WEP

from the drop-down menu. If you

do not want to use WEP encryption, choose

Disabled

(default). The

Bridge’s WEP encryption is unique to Linksys and may conflict with other

manufacturers’ WEP encryption.

If you select 64-bit or 128-bit WEP, you can create a WEP key automati-

cally or manually. Go to step 9a to generate a WEP key automatically. Go

to step 9b to create a WEP key manually.

9a. Enter a passphrase.

•

Passphrase

- This is the code used when logging a wireless device onto the

wireless network. The passphrase is case-sensitive and should not be longer

than 16 alphanumeric characters. Based upon the passphrase created by

you, WEP key settings are automatically generated. This passphrase is only

compatible with other Linksys wireless products.

Click the

Back

button to return to the previ-

ous screen. Then on the
