•

Lease:

Enter a lease time in days, hours and minutes. The wireless client must renew the IP

address when the lease expires. The default lease time is one day.

Configuring Hotspot Settings

If you want the wireless access point to capture and redirect all HTTP (TCP, port 80) requests, use

this feature. For example, a hotel might want all wireless connections to go to its server to show a

branded splash screen.

Enter the URL of the Web server where you want to redirect HTTP requests.

Configuring Advanced Wireless Settings

The WG302v2 provides a bridge between Ethernet wired LANs and 802.11b/g compatible

wireless LAN networks. It provides connectivity between Ethernet wired networks and

radio-equipped wireless notebook systems, desktop systems, print servers, and other devices.

The WG302v2 also supports the following wireless features:

•

Distributed coordinated function (CSMA/CA, Back off procedure, ACK procedure,

retransmission of unacknowledged frames)

•

RTS/CTS handshake

•

Beacon generation

•

Packet fragmentation and reassembly

•

Roaming among access points on the same subnet

From the Advanced Wireless Settings menu, you can configure wireless LAN parameters and

modify QoS queue settings, including Wi-Fi Multimedia (WMM).

Configuring Wireless LAN Parameters

Figure 4-3

shows the Advanced Wireless Settings screen that includes both the Wireless LAN

Parameters section and the QoS Queue Parameters section. For most networks, the default

Advanced Wireless LAN Parameter settings work well.

Table 4-1

describes the Advanced Wireless Parameters.

Modifying QoS Queue Parameters

Figure 4-3

also shows the Quality of Service (QoS) queue section on the Advanced Wireless

Settings page. For most networks, the default QoS queue parameter settings work well.Quality of

Service provides you with the ability to specify parameters on multiple queues for increased

throughput and better performance of differentiated wireless traffic, like Voice-over-IP (VoIP),

other types of audio, video, and streaming media, as well as traditional IP data.

The QoS options on the WG302v2 are as follows:

•

Enable Wi-Fi Multimedia (WMM):

Select Yes or No as required on the Advanced Wireless

Settings menu. The default is No.

WMM is a subset of the 802.11e standard. WMM allows wireless traffic to have a range of

priorities, depending on the kind of data. Time-dependent information, such as video or audio,

has a higher priority than normal traffic. For WMM to function correctly, wireless clients must

also support WMM. If WMM is disabled, you cannot configure Station EDCA parameters.

•

SpectraLink Enabled:

With SpectraLink enabled, SVP traffic takes priority over all other

traffic. The default is always enabled.

Table 4-1

Advanced Wireless LAN Parameters

Field

Description

Enable SuperG Mode

Click Enable to enable Super G Mode.

RTS Threshold

The packet size used to determine whether the access point should use the

CSMA/CD (Carrier Sense Multiple Access with Collision Detection) or the

CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) mechanism

for packet transmission.

Fragmentation Length

This is the maximum packet size used for fragmentation. Packets larger than

the size programmed in this field will be fragmented. The Fragment Threshold

value must be larger than the RTS Threshold value.

Beacon Interval

Specifies the data beacon rate, which is between 20 and 1004.

DTIM Interval

The Delivery Traffic Indication Message specifies the data beacon rate, which is

between 1 and 255.

Preamble Type

A long transmit preamble may provide a more reliable connection or slightly

longer range. A short transmit preamble gives better performance.

Antenna

Select the antenna to use for transmitting and receiving. The antennas are

labeled on the rear panel. The default is Auto.

SpectraLink Voice Priority (SVP) is a QoS approach for Wi-Fi deployments. SVP is an open

specification that is compliant with the IEEE 802.11b standard. SVP minimizes delay and

prioritizes voice packets over data packets on the Wireless LAN, thus increasing the

probability of better network performance.

•

Modify AP EDCA Parameters.

Specify the AP EDCA parameters for different types of data

transmitted from the WG302v2 to the wireless client.

•

Modify Station EDCA Parameters.

Specify the Station EDCA parameters for different types

of data transmitted from the wireless client to the WG302v2. If WMM is disabled, you cannot

configure Station EDCA parameters.

Table 4-2

describes the settings for QoS Queues.

Table 4-2

QoS Queues and Parameters

QoS Queue

Description

Data 0 (Voice)

High priority queue, minimum delay. Time-sensitive data such as VoIP and

streaming media are automatically sent to this queue.

Data 1(Video)

High priority queue, minimum delay. Time-sensitive video data is automatically

sent to this queue.

Data 2 (best effort)

Medium priority queue, medium throughput and delay. Most traditional IP data is

sent to this queue.

Data 3 (Background)

Lowest priority queue, high throughput. Bulk data that requires maximum

throughput and is not time-sensitive is sent to this queue (FTP data, for

example).

AIFS (Arbitration

Inter-Frame Space)

Specifies a wait time (in milliseconds) for data frames. Valid values for AIFS are

1 through 255.

cwMin (Minimum

Contention Window)

Upper limit (in milliseconds) of a range from which the initial random backoff wait

time is determined. Valid values for the “cwmin” are 1, 3, 7, 15, 31, 63, 127, 255,

511, or 1024. The value for cwMin must be lower than the value for cwMax.

cwMax (Maximum

Contention Window)

Upper limit (in milliseconds) for the doubling of the random backoff value. Valid

values for the “cwmax” are 1, 3, 7, 15, 31, 63, 127, 255, 511, or 1024. The value

for cwMax must be higher than the value for cwMin.

Max. Burst Length

Specifies (in milliseconds) the Maximum Burst Length allowed for packet bursts

on the wireless network. A packet burst is a collection of multiple frames

transmitted without header information. Valid values for maximum burst length

are 0.0 through 999.9.

Wireless Bridging and Repeating

The ProSafe 802.11g

lets you build large bridged wireless networks.

Examples of wireless bridged configurations are:

•

Point-to-Point Bridge.

The WG302v2 communicates with another bridge-mode wireless

station. See

“Point-to-Point Bridge Configuration” on page 4-9

.

•

Multi-Point Bridge.

The WG302v2 is the “master” for a group of bridge-mode wireless

stations. Then all traffic is sent to this “master,” rather than to other access points. See

“Multi-Point Bridge Configuration” on page 4-10

.

•

Repeater with Wireless Client Association.

Sends all traffic to the remote AP. See

“Repeater

with Wireless Client Association” on page 4-11

.

These configurations can be set up from the Advanced Access Point Settings page, shown in

Figure 4-4

below.

Note:

The Wireless Bridging and Repeating feature uses the default Security Profile to

send and receive traffic.
