Wireless 802.11 Wi-Fi Multimedia Page
This page allows you to configure the Wi-Fi Multimedia (WMM) Quality of Service (QoS).
Field Descriptions for the Wireless 802.11 Wi-Fi Multimedia Page
Field
Description
WMM Support
Sets WMM support to Auto, On, or Off.
If enabled (Auto or On), the WME Information Element is
included in beacon frame.
No-Acknowledgement
Sets No-Acknowledgement support to On or Off.
When enabled, acknowledgments for data are not transmitted.
Power Save Support
Sets Power Save support to On or Off.
When Power Save is enabled, the AP queues packets for STAs
are in Power Save mode. Queued packets are transmitted
when the station (STA) notifies the AP that it has left Power-
Save mode.

Field
Description
EDCA AP Parameters
Specifies the transmit parameters for traffic transmitted from
the AP to the STA in four Access Categories:
Best Effort (AC_BE)
Background (AC_BK)
Video (AC_VI)
Voice (AC_VO)
Transmit parameters include Contention Window (CWmin and
CWmax), Arbitration Inter Frame Spacing Number (AIFSN), and
Transmit Opportunity Limit (TXOP Limit).
There are also two AP-specific settings: Admission Control and
Discard Oldest First. Admission control specifies if admission
control is enforced for the Access Categories. Discard Oldest
First specifies the discard policy for the queues. On discards
the oldest first; Off discards the newest first.
EDCA STA Parameters
Specifies the transmit parameters for traffic transmitted from
the STA to the AP in four Access Categories:
Best Effort (AC_BE)
Background (AC_BK)
Video (AC_VI)
Voice (AC_VO)
Transmit parameters include Contention Window (CWmin and
CWmax), Arbitration Inter Frame Spacing Number (AIFSN), and
Transmit Opportunity Limit (TXOP Limit).

Wireless 802.11 Bridging Page
This page allows you to configure the WDS features.
Field Descriptions for the Wireless 802.11 Bridging Page
Field
Description
Wireless Bridging
Enables or disables wireless bridging.
Remote Bridges
Table of remote bridge MAC addresses authorized to establish a
wireless bridge. Up to four remote bridges may be connected.
Typically, you will also have to enter your AP’s MAC address on
the remote bridge.
Setting Up Your Wireless LAN
You can use the SBG901 as an access point for a wireless LAN (WLAN) without
changing its default settings.
To enable security for your WLAN, you can do the following on the SBG901:
Encrypt wireless LAN transmissions
Restrict wireless LAN access to further prevent unauthorized WLAN intrusions using
the
Wireless 802.11 Access Control Page
CAUTION:
Never provide your SSID, WPA or WEP passphrase, or WEP
key to anyone who is not authorized to use your WLAN.
Connect at least one computer to the SBG901 Ethernet port to perform configuration.
Do not attempt to configure the SBG901 over a wireless connection.
You need to configure each wireless client (station) to access the SBG901 LAN as
described in
Installing Wireless Clients
.
Another step to improve wireless security is to place wireless components away from
windows. This decreases the signal strength outside the intended area.

Encrypting Wireless LAN Transmissions
To prevent unauthorized viewing of data transmitted over your WLAN, you must encrypt
your wireless transmissions. Choose one:
Encrypting Wireless LAN Transmissions
Configure on the SBG901
Required on Each Wireless Client
If all of your wireless clients
support Wi-Fi Protected Access
(WPA), Motorola recommends
configuring WPA on the SBG901
If you use a local pre-shared key (WPA-PSK)
passphrase, you must configure the identical
passphrase to the SBG901 on each wireless client.
Home and small-office settings typically use a local
passphrase.
Otherwise, configure WEP on the
SBG901
You must configure the identical WEP key to the
SBG901 on each wireless client.
If all of your wireless clients support WPA encryption, Motorola recommends using WPA
instead of WEP because WPA:
Provides much stronger encryption and is more secure
Provides authentication to ensure that only authorized users can log in to your WLAN
Is much easier to configure
Uses a standard algorithm on all compliant products to generate a key from a textual
passphrase
Will be incorporated into the new IEEE 802.11i wireless networking standard
For new wireless LANs, Motorola recommends purchasing client adapters that support
WPA encryption.

Installing Wireless Clients
Note
: Use the SBG901 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.
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 SBG901
Configuring a Wireless Client for WPA or WPA2
Configuring WEP on the SBG901
Configuring a Wireless Client for WEP
Configuring the Wireless Network
Name on the SBG901
Configuring a Wireless Client with the Network Name
(SSID)
Configuring a MAC Access Control
List on the SBG901
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 SBG901, you
must configure the same passphrase (key) on each wireless client. The SBG901 cannot
authenticate a client if:
WPA is enabled on the SBG901, but not on the client
The client passphrase does not match the SBG901 PSK Passphrase
CAUTION:
Never provide the PSK Passphrase to anyone who is not
authorized to use your WLAN.
