Channel Number

It is the radio channel used by the wireless LAN. All

devices in the same wireless LAN should use the same

channel. Please select the country you are located and

designate a channel that the router will use. If you want

to let the router automatically to find an available channel

with the highest signal strength, please select “Auto”.

Radio Power (mW)

Set the maximum output power of the router. The higher

output power, the wider coverage range.

Associated Clients

Click “Show Active Clients” button and you can see the

wireless clients connected to the router.

When you finish, click ‘Apply Changes’. You’ll see the following message

displayed on web browser:

Press ‘Continue’ to save the settings made and back to web management

interface; press ‘Apply’ to save the settings made and restart the router so the

settings will take effect after it reboots.

5.2.4.2. Advanced Settings

This page allows advanced users who have sufficient knowledge of wireless LAN.

These setting shall not be changed unless you know exactly what will happen for

the changes you made on your router.

Parameter

Description

Authentication Type

There are three authentication types: "Open System",

"Shared Key" and "Auto".

Open System: Open System authentication is not

required to be successful while a client may decline to

authenticate with any particular other client.

Shared Key: Shared Key is only available if the WEP

option is implemented. Shared Key authentication

supports authentication of clients as either a member of

those who know a shared secret key or a member of

those who do not. IEEE 802.11 Shared Key

authentication accomplishes this without the need to

transmit the secret key in clear. Requiring the use of the

Page 68 / 124

WEP privacy mechanism.

Auto: Auto is the default authentication algorithm. It will

change its authentication type automatically to fulfill

client’s requirement.

Fragmentation

Threshold

Fragment Threshold specifies the maximum size of

packet during the fragmentation of data to be transmitted.

If you set this value too low, it will result in bad

performance. Enter a value from 256 to 2346.

RTS Threshold

This value should remain at its default setting of 2347.

Should you encounter inconsistent data flow, only minor

modifications are recommended. If a network packet is

smaller than the preset “RTS threshold” size, the

RTS/CTS mechanism will not be enabled. The wireless

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.

Beacon Interval

The interval of time that this wireless router broadcast a

beacon. Beacon is used to synchronize the wireless

network. The range for the beacon period is between 20

and 1024 with a default value of 100 (milliseconds).

Data Rate

The rate of data transmission should be set depending

on the speed of your wireless network. You should select

from a range of transmission speeds, or you can select

Auto

to have the wireless 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 setting is “Auto”.

Preamble Type

The Preamble Type defines the length of the CRC

(Cyclic Redundancy Check) block for communication

between the router and wireless stations. Make sure to

select the appropriate preamble type. Note that high

network traffic areas should use the “Short Preamble”.

CRC is a common technique for detecting data

transmission errors.

Broadcast SSID

If this option is enabled, the router will automatically

transmit the network name (SSID) into open air at regular

interval. This feature is intended to allow clients to

dynamically discover the router. If this option is disabled,

the router will hide its SSID. When this is done, the

clients cannot directly discover the router

and MUST be

configure with the SSID for accessing to the router. It is

used to protect your network from being accessed easily.

Relay Blocking

When you enable this function, wireless clients will not be

able to directly access other wireless clients.

Protection

This is also called CTS Protection. It is recommended to

enable the protection mechanism. This mechanism can

decrease the rate of data collision between 802.11b and

802.11g/802.11n wireless stations. When the protection

mode is enabled, the throughput of the AP will be a little

lower due to many of frame traffic should be transmitted.

Aggregation

This function is used to join multiple data packets for

transmission as a single unit to increase network

efficiency.

Short GI

The 802.11n draft specifies two guard intervals: 400ns

(short) and 800ns (long).

Support of the 400ns GI is

optional for transmit and receive.

will increase network efficiency.

When you finish, click ‘Apply Changes’. You’ll see the following message

displayed on web browser:

Press ‘Continue’ to save the settings made and back to web management

interface; press ‘Apply’ to save the settings made and restart the router so the

settings will take effect after it reboots.

5.2.4.3. Security

This router provides complete wireless LAN security functions, include WEP,

IEEE 802.1x, IEEE 802.1x with WEP, WPA with pre-shared key and WPA with

RADIUS. With these security functions, you can prevent your wireless LAN from

illegal access. Please make sure your wireless stations use the same security

function.
