Wireless > Advanced Wireless Settings

This

Wireless > Advanced Wireless Settings

screen is used

to set up the Router’s advanced wireless functions. These

settings should only be adjusted by an expert administrator

as incorrect settings can reduce wireless performance.

Advanced Wireless

AP Isolation

This isolates all wireless clients and wireless

devices on your network from each other. Wireless devices

will be able to communicate with the Router but not with

each other. To use this function, select

Enable

. AP Isolation

is on

Disable

by default.

Frame Burst

Enabling this option should provide your

network with greater performance, depending on the

manufacturer of your wireless products. To turn on the

Frame Burst option, select

Enable

. The default is

Disable

Authentication Type

The default is set to

Auto

, which

allows either Open System or Shared Key authentication

to be used. With

Open System

authentication, the sender

and the recipient do NOT use a WEP key for authentication.

With

Shared Key

authentication, the sender and recipient

use a WEP key for authentication.

Basic Rate

The Basic Rate setting is not actually one rate

of transmission but a series of rates at which the Router

can transmit. The Router will advertise its Basic Rate to

the other wireless devices in your network, so they know

which rates will be used. The Router will also advertise that

it will automatically select the best rate for transmission.

The default setting is

Default

, when the Router can

transmit at all standard wireless rates. The Basic Rate is

not the actual rate of data transmission. If you want to

specify the Router’s rate of data transmission, configure

the Transmission Rate setting.

Transmission Rate

The rate of data transmission should

be set depending on the speed of your wireless network.

You can select from a range of transmission speeds, or you

can select

Auto

to have the Router automatically use the

fastest possible data rate and enable the Auto-Fallback

feature. Auto-Fallback will negotiate the best possible

connection speed between the Router and a wireless

client. The default value is

Auto

CTS Protection Mode

CTS (Clear-To-Send) Protection

Mode’s

default

setting

Auto

The

Router

will

automatically use CTS Protection Mode when your

Wireless-N and Wireless-G products are experiencing

severe problems and are not able to transmit to the

Router in an environment with heavy 802.11b traffic. This

function boosts the Router’s ability to catch all Wireless-

N and Wireless-G transmissions but will severely decrease

performance.

Beacon Interval

The default value is

100

. Enter a value

between 20 and 1000 milliseconds. The Beacon Interval

value indicates the frequency interval of the beacon. A

beacon is a packet broadcast by the Router to synchronize

the wireless network.

Chapter 3

Advanced Configuration

DTIM Interval

This value, between 1 and 255, indicates

the 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 messages 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 messages. The default value is

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

Should you encounter inconsistent data

flow, only minor reduction of the default value, 2346, is

recommended. If a network packet is smaller than the

preset RTS threshold size, the RTS/CTS mechanism will

not be enabled. The Router sends Request to Send (RTS)

frames to a particular receiving station and negotiates

the sending of a data frame. After receiving an RTS, the

wireless station responds with a Clear to Send (CTS) frame

to acknowledge the right to begin transmission. In most

cases, keep its default value of

2346
