Selects the network mode in which to run the DVW326. The

options are:



54g auto – self adaptive connection



54g performance – highest speed



54g LRS – limited speed



802.11b – connections to 11b clients only.

This field can be set only if 802.11-n Mode is set to

Off

in the

Radio screen as discussed on

Using the Wireless Radio Option

on page 68

XPress™ Technology

Enables or disables the XPress feature. XPress™ is a

standards-based frame-bursting approach to improve 802.11g

wireless LAN performance developed by Broadcom. When

Xpress enabled, aggregate throughput can improve up to 27%

in 802.11g-only networks, and up to 75% in mixed networks

comprised of 802.11g and 802.11b standard equipment.

802.11n Protection

Defines the 802.11n Protection setting.



Auto

- the DVW326 uses Request to Send/Clear to Send

(RTS/CTS) to improve the performance in 802.11 mixed

environments.



Off

- the 802.11 performance is maximized under most

conditions, while the other 802.11 modes (802.11b, etc.) are

secondary.

Short Guard Interval

Defines a transmission interval so data transmissions do not

interfere with each other.

Basic Rate Set

Selects the rate that all wireless clients must support to connect

to the DVW326. The options are

All

and

Default

Multicast Rate

Specifies the rate at which multicast packets are transmitted and

received on your wireless network.

NPHY Rate

Sets the Physical Layer (NPHY) rate. Choose Legacy Rate to

use 802.11a or 802.11g modes, and then choose the rate in the

Legacy Rate field.

Legacy Rate

Sets the wireless rate to the chosen 802.11a or 802.11g legacy

rate.

Beacon Interval

Specifies the Beacon Interval from 100 to 6553 5ms. This value

indicates the frequency interval of the beacon. A beacon is a

packet broadcast by the DVW326 to keep the network

synchronized. A beacon includes information regarding the

wireless networks service area, the access point address, the

broadcast destination addresses, a time stamp, delivery traffic

indicator maps, and the Traffic Indicator Message (TIM).

DTIM Interval

Specifies the DTIM interval from 3 to 255ms. This value

indicates how often the DVW326 sends out a Delivery Traffic

Indication Message (DTIM). Lower settings result in more

efficient networking, while preventing your wireless clients from

dropping into power-saving sleep mode. Higher settings allow

your wireless clients to enter sleep mode, thus saving power,

but interferes with wireless transmissions.

Using the Access Control Option

Use the

Access Control

option to configure which clients can access your wireless

network.

Steps

To configure client access:

Click

Wireless

from the main menu.

2. Click

Access Control

from the left side menu.

Field descriptions are listed below the

screen example.

Fragmentation

Threshold

Specifies the fragmentation threshold packet size between 256-

2346 bytes. Fragmentation takes place when a packet’s size

exceeds the fragmentation threshold.

RTS Threshold

Specifies the RTS threshold from 0 to 2347ms. This setting

determines how large a packet can be before the DVW326

coordinates transmission and reception to ensure efficient

communication. This value should remain at its default setting of

2347 bytes. If you encounter inconsistent data flow, minor

modification to this setting is recommended.

Wireless Interface

Defines the network name (SSID) and MAC address for which

you are setting access control parameters.

MAC Restrict Mode

Controls wireless access to your network by MAC address.



Disabled

turns off MAC restrictions and allows any

wireless client to connect to this device. However, if you

use other security mechanisms for access to the wireless

network, clients must still adhere to those restrictions.



Allow

creates a list of wireless clients that can connect to

the wireless network. Enter the MAC addresses of these

clients in the MAC Addresses fields. MAC addresses not

on the list, are not allowed access to your wireless

network.



Deny

creates a list of wireless clients that you do not

want to have access to your wireless network. Enter the

MAC addresses of these clients in the MAC Addresses

fields.

MAC Addresses

Defines the MAC addresses. Note: You may cut and paste

MAC addresses from the connected clients list at the bottom

of the screen.

Apply

Saves changes when clicked.

Connected Clients

Lists wireless clients currently connected listed by MAC

address.



MAC Address

– Displays the MAC addresses entered in

the MAC Addresses field (see above).



Age(s)

– Displays the duration since the wireless client’s

polled values were sent to the device. The values include

all information shown on this screen. The lower the

number, the more current its data.



RSSI(dBm)

– Displays the received signal strength from

the device to the wireless cable modem. This value is

commonly used to assist in troubleshooting wireless

performance issues. A signal strength between 0dBm

and -65dBm is considered optimal. Levels of -66dBm and

lower (for example, -70, -80, etc.) have a downward

impact on wireless data throughput. Refer to

Understanding Received Signal Strength on page 83

for

more information.



IP Address

– Displays the IP address assigned to this

wireless client.



Host Name

– Displays the host name of the wireless

client.



Mode

– Indicates the applicable 802.11a/b/g/n standard

used by the connected client device.



Speed (kbps)

– Displays the maximum theoretical link

speed negotiated

between the wireless gateway and the

client, not including the overhead associated with

encryption, and so on. For example, actual speeds with

WEP encryption enabled a

re typically less than half of the

negotiated link speed. TKIP encryption can also affect

performance. AES is the most efficient and secure with

the highest throughput possible. You can disable WMM if

throughput on some client adapters is adversely affected.

Using the Wi-Fi Multimedia Option

Use the Wi-Fi Multimedia option to configure the quality of service (QoS) to ensure the

best service in your wireless networks.



Controls WLAN transmission priority on packets transmitted over the wireless network.



Wi-Fi Multi-Media Quality of Service (WMM QoS) is a part of the IEEE 802.11e QoS

enhancement to certified Wi-Fi wireless networks.



WMM QoS prioritizes wireless traffic according to the delivery requirements of the

individual user and applications. On wireless access points without WMM QoS, all

traffic streams are given the same access priority to the wireless network. If a new

traffic stream creates a data transmission demand that exceeds the current network

capacity, the new traffic stream reduces the throughput of the other traffic streams.



WMM QoS capability allows you to assign access categories (ACs) to various packet

streams. The assigned AC of a packet stream depends on the packet’s priority, such

as a priority assigned by an application (also referred to as a user priority (UP). An AC

may include a common set of enhanced distributed channel access (EDCA)

parameters used by QoS to contend for a channel to transmit packets with certain

priorities.

Different ACs can be associated with different power saving parameters. For example,

one power saving parameter might be the delivery mechanism used by an access

point (AP) to deliver packets to a station (STA) that is operating in a reduced power

mode.



WMM transmit opportunity (TXOP) is assigned to each access point. The bounded

time interval during which a station can send as many frames as possible as long as

the transmission time does not extend past the maximum duration of the TXOP. If a

frame is too large to be transmitted in a single TXOP, it should be fragmented into

smaller frames. Using TXOP reduces the problem of low rate stations gaining too

much channel time in the legacy 802.11 DCF MAC. A TXOP time interval of 0 means

it is limited to a single MAC service data unit (MSDU) or MAC management protocol

data unit (MMPDU).

Note

WMM may need to be disabled to avoid throughput impacts to other wireless devices.

Steps

To configure the multimedia wireless option:

Click

from the main menu.

2. Click

Description

WMM Support

Enables (On) or disables (Off) WMM support.

No-Acknowledgement

Enables (On) or disables (Off) acknowledging data frames. In

QoS mode, frames to send can have two values: QosAck and

QosNoAck. Frames with QosNoAck are not acknowledged,

avoiding the retransmission of highly time-critical data.

Power Save Support

Enables (On) or disables (Off) power savings. WMM Power

Save increases the efficiency and flexibility of data transmission.

The wireless client device can “doze” between packets to save

power, while the wireless access point buffers downlink frames.

The application chooses the time to wake up and receive data

packets to maximize power conservation without sacrificing

quality of service.

Apply

Saves changes to the WMM settings above.

EDCA AP Parameters

Allows you to prioritize wireless network traffic. Enhanced

Distributed Channel Access – Access Point (EDCA-AP)

provides four access categories (ACs):



AC_BE

– Best Effort, medium throughput and delay. Most

traditional IP data is sent to this queue.



AC_BK

– Background, high throughput. Bulk data that

requires maximum throughput and is not time-sensitive is

sent to this queue (for example, FTP data).



AC_VI

– Video



AC_VO

– Voice
