Installing Wireless Clients

Note

: Use the SBG941 Installation

CD-ROM to set the client security. The passcode is

located on the

MAC Label

.

For each wireless client computer (station), install the wireless adapter by following the

instructions supplied with the adapter. Be sure to:

1.

Insert the CD-ROM for the adapter in the CD-ROM drive on the client.

2.

Install the device software from the CD or the modem.

3.

Insert the adapter in the PCMCIA or PCI slot or connect it to the USB port.

4.

Configure the adapter to obtain an IP address automatically.

You may need to do the following to use a wireless client computer to access the

Internet:

Installing Wireless Clients

If You Performed:

On Each Client, You Need to Perform:

Configuring WPA on the SBG941

Configuring a Wireless Client for WPA or WPA2

Configuring WEP on the SBG941

Configuring a Wireless Client for WEP

Configuring the Wireless Network

Name on the SBG941

Configuring a Wireless Client with the Network Name

(SSID)

Configuring a MAC Access Control List

on the SBG941

No configuration on client required

Configuring a Wireless Client for WPA

If you enabled WPA and set a PSK Passphrase by configuring WPA on the SBG941, you

must configure the same passphrase (key) on each wireless client. The SBG941 cannot

authenticate a client if:

•

WPA is enabled on the SBG941, but not on the client

•

The client passphrase does not match the SBG941 PSK Passphrase

CAUTION

Never provide the PSK Passphrase to anyone who is not authorized to use your WLAN.

Configuring a Wireless Client for WEP

If you enabled WEP and set a key by configuring WEP on the SBG941, you must

configure the same WEP key on each wireless client. The SBG941 cannot authenticate a

client if:

•

Shared Key Authentication is enabled on the SBG941 but not on the client

•

The client WEP key does not match the SBG941 WEP key

For all wireless adapters, you must enter the 64-bit or 128-bit WEP key generated by the

SBG941.

CAUTION

Never provide the WEP key to anyone who is not authorized to use your WLAN.

Configuring a Wireless Client with the Network Name (SSID)

After you specify the network name on the Wireless Primary Network Page, many

wireless cards or adapters automatically scan for an access point, such as the SBG941

and the proper channel and data rate. If your card requires you to manually start scanning

for an access point, do so following the instructions in the documentation supplied with

the card. You must enter the same SSID in the wireless configuration setup for the

device to communicate with the SBG941.

Troubleshooting

If the solutions listed here do not solve your problem, contact your service provider.

Before calling your service provider, try pressing the Reset button on the rear panel of

the SBG941.

Note

: Press

RESET

to restore the default settings. You will lose your custom

configuration settings, including Parental Control, Firewall, and Advanced settings.

Resetting the SBG941 may take 5- to 30 minutes. Your service provider may ask for the

status of the lights as described in

Front-Panel LEDs and Error Conditions

.

Solutions

Table 2 – Troubleshooting Solutions

Problem

Possible Solution

Power light is off

Check that the SBG941 is properly plugged into the electrical outlet.

Check that the electrical outlet is working.

Press the Reset button.

Cannot send or

receive data

On the front panel, note the status of the LEDs and refer to

2

Table 3 –

Front Panel LEDs and Error Conditions

to identify the error. If you

have cable TV, check that the TV is working and the picture is clear. If

you cannot receive regular TV channels, the data service will not

function.

Check the coaxial cable at the SBG941 and wall outlet. Hand-tighten if

necessary.

Check the IP address. Follow the steps for verifying the IP address for

your system, see

Verifying the IP Address in Windows XP

or

Verifying

the IP Address in Windows Vista

. Call your service provider if you

need an IP address.

Check that the Ethernet cable is properly connected to the SBG941

and the computer.

If a device is connected via the Ethernet port, verify connectivity by

checking the LINK LEDs on the rear panel.

Wireless client(s) cannot

send or receive data

Perform the first four checks in “Cannot send or receive data.”

Check the Security Mode setting on the Wireless Primary Network

Page:

•

If you enabled WPA and configured a passphrase on the SBG941,

be sure each affected wireless client has the identical passphrase.

If this does not solve the problem, check whether the wireless

client supports WPA.

•

If you enabled WEP and configured a key on the SBG941, be sure

each affected wireless client has the identical WEP key. If this does

not solve the problem, check whether the client’s wireless adapter

supports the type of WEP key configured on the SBG941.

•

To temporarily eliminate the Security Mode as a potential issue,

disable security.

After resolving your problem, be sure to re-enable wireless security.

•

On the Wireless Access Control Page, be sure the MAC address for

each affected wireless client is correctly listed.

Slow wireless

transmission speed with

WPA enabled

On the Wireless Primary Network Page, check whether the WPA

Encryption type is TKIP. If all of your wireless clients support AES,

change the WPA Encryption to AES.
