Network Name (SSID)

When you are browsing for available wireless networks, this

is the name that will appear in the list (unless Visibility Status

is set to Hidden, see below). This name is also referred to as

the SSID.

Multiple SSID (1~7)

To add additional wireless Network Names simply add the

name to the Multiple SSID field and click on apply at the

bottom of the page.

Broadcast Network

Name (SSID)

SSID broadcast can be disabled.

AP Isolation

If enabled, will isolate communication between the clients

connected to router wirelessly.

MBSSID Isolation

If enabled, will isolate communication between the clients

from different SSID.

BSSID

MAC Address of AP

Frequency (Channel)

Radio Channel that wireless AP/Router uses to communicate

with wireless clients.

HT Physical Mode description

Operating Mode

°

Mixed mode: Provides backward compatibility with

IEEE 802.11n/g/b devices.

°

Green Field: Used for pure network of 802.11n access

point and clients, taking full advantage of high-

throughput capabilities of MIMO architecture.

Channel Bandwidth

20 MHz: Allows only single channel operation (20MHz).

20/40 MHz: Allows both single channel operations.

Guard Interval

The guard interval is the period in nanoseconds that the

Gateway listens between packets.

MCS(Modulation

Coding Scheme):

The Modulation and Coding Scheme(MCS) is a value that

determines the modulation, coding and number of spatial

channels. ( Options: value [range] = 0~7 (1 Tx Stream), 8~15

(2 Tx Stream), 32 and auto (33). Default is auto.

Reverse Direction Grant

When enabled Reverse Direction Grant, the wireless

AP/Router can reduce the transmitted data packet collision by

using the reverse direction protocol. The RDG improves

transmission performance and scalability in a wireless.

Aggregation MSDU

This option enables MAC Service Data Unit (MSDU)

aggregation. Default is disable.

Auto Block ACK

Select to block ACK (Acknowledge Number) or not during

data transferring.

Decline BA Request

Select to reject peer BA-Request or not

HT TxStream

HT means High Throughput. The number of HT TxStream

means how many antennas will transmit data

simultaneously.

HT RxStream

The number of HT RxStream means how many antennas

will receive data simultaneously.

Parameter

Description

BG Protection

Mode

This mode is a protection mechanism that prevents collisions among 802.11b/g

modes. Below are the choices.

Auto

BG protection mode goes ON or OFF automatically as needed.

°

ON:

BG protection mode is always ON.

°

OFF:

BG protection mode is always OFF.

Beacons

Beacons are packets sent by a wireless router to synchronize wireless devices.

Specify a Beacon Period value between 20 and 1000. The default value is set to

100 milliseconds

DTIM

A DTIM is a countdown informing clients of the next window for listening to

broadcast and multicast messages. When the wireless router has buffered

broadcast or multicast messages for associated clients, it sends the next DTIM

with a DTIM Interval value. Wireless clients detect the beacons and awaken to

receive the broadcast and multicast messages. The default value is 1. Valid

settings are between 1 and 255.

Fragment

Threshold

Wireless frames can be divided into smaller units (fragments) to improve

performance in the presence of RF interference and at the limits of RF coverage.

Fragmentation will occur when frame size in bytes is greater than the

Fragmentation Threshold. This setting should remain at its default value of 2346

bytes. Setting the Fragmentation value too low may result in poor performance.

RTS Threshold

When an excessive number of wireless packet collisions are occurring, wireless

performance can be improved by using the RTS/CTS (Request to Send/Clear to

Send) handshake protocol. The wireless transmitter will begin to send RTS

frames (and wait for CTS) when data frame size in bytes is greater than the RTS

Threshold. This setting should remain at its default value of 2346 bytes.

Tx Power

Adjusts the power of radio signals transmitted from the AP. The higher the

transmission power, the farther the transmission range. You also have to ensure

that high-power signals do not interfere with the operation of other radio devices

in the service area.

Short Preamble

Enables the length of the signal preamble that is used at the start of a

transmission.

Short Slot

Sets the basic unit of time the wireless AP/Router uses for calculating waiting

times before data is transmitted. Enabling a short time slot can increase data

throughput on the wireless AP/Router, but requires that all clients can support a

short time slot.

Tx Burst

Allows the wireless Router to deliver better throughput in the same period and

environment in order to increase speed.

Pkt_Aggregate

Increase efficiency by aggregating multiple packets of application data into a

single transmission frame. In this way, 802.11n networks can send multiple data

packets with the fixed overhead cost of just a single frame.

WMM

Here you can configure WMM parameters.

2-7-3 Wireless Security

It’s very important to set wireless security settings properly

.

If you don’t, hackers and

malicious users can reach your network and valuable data without your consent and this

will cause serious security problem.

To set wireless security settings, Please click ‘

Wireless Security

’ menu on the left of

web management interface, under the ‘

Wireless

’ tab and then follow the instructions

mentioned below to set wireless security settings:

Wireless Security if selected Disable

When you select this mode, data encryption is disabled, and every wireless device in

proximity will be able to connect to your wireless router if no other security measure is

enabled (like Access Control or disable SSID broadcast).

Only use this option when you really want to allow everyone to use your wireless

router, and you don’t care if there’s someone reading the data you transfer over

network without your consent.

A. WEP

When you select this mode, the wireless router will use WEP encryption, and the

following setup menu will be shown on your web browser.

Parameter

Description

Default Tx Key

When ‘WEP’ Encryption is enabled then ‘Key 1’ will appear in

this field.

Key Format

There are two types of key format: ASCII and Hex. When you

select a key format, the number of characters of key will be

displayed.

Encryption Key 1

Input WEP key characters here, the number of characters must

be the same as the number displayed at ‘Key Format’ field.

You can use any alphanumerical characters (0-9, a-z, and A-Z)

if you select ‘ASCII’ key format, and if you select ‘Hex’ as key

format, you can use characters 0-9, a-f, and A-F. You must

enter at least one encryption key here, and if you have entered

multiple WEP keys, they should not be the same.

Policy

If Enabled, as per the policy defined clients will be either

allowed or rejected to connect wireless network.
