Select SSID
Your Service Set Identifier (SSID),sets your Wireless Network Name.You can
connect multiple devices including Laptops,Desktop PCs and PDAs to your
Wireless Gateway.To get additional devices connected,scan for a network,and
locate the SSID shown on your Wireless Security Card.If the SSID does not match,
access is denied.
Network
Authentication
This option is used for authentication to the wireless network.Each authentication
type has its own settings as illustrated below.For example,selecting 802.1X
authentication will reveal the RADIUS Server IP address,Port and Key fields.
WEP Encryption will also be enabled.
The settings for WPA authentication are shown below.
WEP
Encryption
This option indicates whether data sent over the network is encrypted.The same
network key is used for data encryption and network authentication.Whilst four
network keys can be defined,only one can be used at any one time.
Use the network key found in the drop down list.
Encryption
Strength
This drop-down list box will display when WEP Encryption is enabled.
The key strength is proportional to the number of binary bits comprising the key.
This means that keys with a greater number of bits have a greater degree of
security and are considerably more difficult to crack.Encryption strength can
be set to either 64-bit or 128-bit.A 64-bit key is equivalent to 5 ASCII characters
or 10 hexadecimal numbers.A 128-bit key contains 13 ASCII characters or 26
hexadecimal numbers.FYI:Each key contains a 24-bit header (an initiation vector)
which enables parallel decoding of multiple streams of encrypted data.

Description
AP Isolation
Select On or Off.By enabling this feature,wireless clients associated with the
Access Point can be linked.
Band
The new amendment allows IEEE 802.11g units to fall back to speeds of 11 Mbps,
so IEEE 802.11b and IEEE 802.11g devices can coexist in the same network.The
two standards apply to the 2.4 GHz frequency band.IEEE 802.11g creates data-
rate parity at 2.4 GHz with the IEEE 802.11a standard,which has a 54 Mbps rate
at 5 GHz.(IEEE 802.11a has other differences compared to IEEE 802.11b or g,such
as offering more channels.)
Channel
Allows selection of a specific channel (1-14) or Auto mode.
Auto Channel
Timer (min)
The Auto Channel times the length it takes to scan in minutes.
54g Rate
In Auto (default) mode, your Gateway uses the maximum data rate and lowers
the data rate dependent on the signal strength.The appropriate setting is
dependent on signal strength.Other rates are discrete values between 1 to 54
Mbps.
Multicast Rate
Setting for multicast packet transmission rate.(1-54 Mbps)
Basic Rate
Sets basic transmission rate.
Fragmentation
Threshold
A threshold (in bytes) determines whether packets will be fragmented and at
what size.Packets that exceed the fragmentation threshold of an 802.11 WLAN
will be split into smaller units suitable for the circuit size.Packets smaller than
the specified fragmentation threshold value however are not fragmented.
Values between 256 and 2346 can be entered but should remain at a default
setting of 2346.Setting the Fragmentation Threshold too low may result in
poor performance.
RTS Threshold
Request To Send (RTS) specifies the packet size that exceeds the specified
RTS threshold,which then triggers the RTS/CTS mechanism.Smaller packets
are sent without using RTS/CTS.The default setting of 2347 (max length) will
disables the RTS Threshold.
DTIM Interval
Delivery Traffic Indication Message (DTIM) is also known as Beacon Rate.
The entry range is a value between 1 and 65535.A DTIM is a countdown
variable that informs clients of the next window for listening to broadcast
and multicast messages.When the AP has buffered broadcast or multicast
messages for associated clients,it sends the next DTIM with a DTIM Interval
value.AP Clients hear the beacons and awaken to receive the broadcast and
multicast messages.The default is 1.
Beacon Interval
The amount of time between beacon transmissions in is milliseconds.
The default is 100 ms and the acceptable range is 1 – 65535.The beacon
transmissions identify the presence of an access point.By default,network
devices passively scan all RF channels listening for beacons coming from
access points.Before a station enters power save mode,the station needs the
beacon interval to know when to wake up to receive the beacon.
Xpress™
Technology
Broadcom’s Xpress™ Technology is compliant with draft specifications of two
planned wireless industry standards.It has been designed to improve wireless
network efficiency.Default is disabled.

Description
54g Mode
Select Auto mode for greatest compatibility.Select Performance mode for the
fastest performance among 54g certified equipment.Select LRS mode if you
are experiencing difficulty with legacy 802.11b equipment.If this does not
work,you may also try 802.11b only mode.
54g Protection
In Auto mode,the gateway will use RTS/CTS to improve 802.11g performance in
mixed 802.11g/802.11b networks.Turning protection Off will maximize 802.11g
throughput under most conditions.
Preamble Type
Short preamble is intended for applications where maximum throughput is
desired but it does not work with legacy equipment.Long preamble works with
the current 1 and 2 Mbit/s DSSS specification as described in IEEE Std 802.11-
1999
Transmit Power
Set the power output (by percentage) as desired.

MAC FILTER
This screen appears when Media Access Control (MAC) Filter is selected.This option allows access
to be restricted based upon the unique 48-bit MAC address.
To add a MAC Address filter,click the Add button shown below.
To delete a filter,select it from the table below and click the Remove button.
Option
Description
MAC Restrict Mode
Disabled – Disables MAC filtering
Allow – Permits access for the specified MAC addresses.
NOTE:
Add a wireless device’s MAC address before clicking the Allow radio button or else you
will need to connect to the Gateway’s web user interface using the supplied yellow
Ethernet cable and add the wireless device’s MAC address.
Deny – Rejects access for the specified MAC addresses
MAC Address
Lists the MAC addresses subject to the MAC Restrict Mode.The Add button
prompts an entry field that requires you type in a MAC address in a two-
character,6-byte convention:xx:xx:xx:xx:xx:xx where xx are hexadecimal
numbers.A maximum of 60 MAC addresses can be added.
Enter the MAC address on the screen below and click Save/Apply.
