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

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:
