Description
54g
TM
Mode
Auto by default.
Basic Rate Set
Select the wireless transmission rate to a particular speed or leave it
as default (Auto) to allow the AP adjusts speed automatically.
54g
TM
Protection
In Auto mode (Protection ON), the device will use RTS/CTS
control to improve 802.11g performance in mixed networks.
Turning protection OFF will maximize 802.11g throughput under
most conditions.
XPress
TM
Technology
When Xpress is turned on, aggregate throughput can improve
significantly.
Afterburner
TM
Technology
Afterburner technology is an enhancement for the 54g™ platform,
Broadcom's maximum performance implementation of the IEEE
802.11g standard.
Rate
Forces the transmission rate for the cable modem/router to a
particular speed. Auto will provide the best performance in nearly
all situations.
Beacon Interval
A beacon is a packet broadcast by the router to synchronize the
wireless network. The default interval is 100 ms.
DTIM Interval
Interval of the Delivery Traffic Indication Message (DTIM). A
DTIM field is a countdown field informing clients of the next
window for listening to broadcast and multicast messages. When
the router has buffered broadcast or multicast for associated clients,
it sends the next DTIM with a DTIM Interval value. Its clients hear
the beacons and awaken to receive the broadcast and multicast
message. The default value is 1.
Fragmentation Threshold
This value specifies the maximum size for a packet before data is
fragmented into multiple packets. If you experience a high packet
error rate, you may slightly increase the fragmentation threshold.
Setting the fragmentation threshold too low may result in poor
network performance. Only minor reduction of the default value is
recommended. In most cases, it should remain at its default value
of 2346.
RTS Threshold
Using this setting can regulate your wireless network if you
experience any inconsistent data flow. Make only minor
adjustments to the default value of 2347.
NPHY Rate
Set the Physical Layer (NPHY) rate. These rates are only applicable
when the
802.11n mode
is configured as
Automatic
.
802.11n Protection
The 802.11g standards provide a protection method so 802.11g and
802.11b devices can co-exist in the same network without
“speaking” at the same time. Do not disable 802.11n protection if
82
Page 83 / 108
there is a possibility that 802.11b or 802.11g devices will use your
wireless network. In
Auto
mode, the wireless devices use RTS/CTS
to improve 802.11n performance in mixed 802.11g/802.11b
networks. Turn protection off to maximize 802.11n throughput
under most conditions.
Multicast Rate
Specify the rate at which multicast packets are transmitted and
received on your wireless network. Multicast packets are used to
send a single message to a set of recipients in a defined group.
Teleconferencing, videoconferencing and group email are some
examples of multicast applications. Specifying a high multicast rate
may improve performance of multicast features. The rates are in
Mbps. You can select

Access Control
This page allows you to control which wireless clients can access your wireless network. It also
provides information about wireless clients connected to your access point.
To access the
Access Control
page:
1
Click
Wireless
in the menu bar.
2
Then click the
Access Control
submenu.
Figure 38 shows an example of the menu and Table 28 describes the items you can select.

Description
Wireless
Interface
Select the wireless interface to configure the access control list.
MAC Restrict
Mode
Select whether wireless clients with the specified MAC address are allowed or
denied wireless access. To allow all clients, select Disabled.
MAC Addresses
Shows the list of wireless client MAC addresses to allow or deny based on
the Restrict Mode setting. Valid MAC address formats are
XX:XX:XX:XX:XX:XX and XX-XX-XX-XX-XX-XX.
Connected
Clients
Shows the list of connected wireless clients. When a client connects
(associates) to the network, it is added to the list; when a client leaves
(disassociates) from the network, it is removed from the list. For each client,
the age (in seconds), estimated average receive signal strength (in dBm), IP
address, and host name are presented. The age is the amount of time elapsed
since data was transmitted to or received from the client.
WMM (WiFi Multimedia)
The WMM page allows you to configure WMM (WiFi Multimedia) feature. WMM is a subset of
the 802.11e wireless LAN (WLAN) specification that enhances quality of service (QoS) on a
network by prioritizing data packets according to their categories.
WMM enhances QoS at the wireless driver level. It provides a mechanism to prioritize wireless data
traffic to and from the associated (WMM capable) stations.
If you enable the WMM feature, you may need to decide whether or not to broadcast cable
modem/router’s network name. Broadcasting allows you to easily recognize your wireless network
in the list of available networks. Once you have configured your wireless clients, it is recommended
that you disable the broadcasting feature.
To access the
WMM
page:
1
Click
Wireless
in the menu bar.
2
Then click the
WMM
submenu.
Figure 39 shows an example of the menu and Table 29 describes the items you can select.
