change the encryption key frequently. So the encryption key is not easy to be broken by

hackers. This can improve security very much.

Select “WPA Pre-share Key” for the “Encryption” mode if you wish to use WPA-PSK or WPA2-

PSK to encrypt your wireless network.

Parameters

Description

WPA Unicast Cipher Suite

Available options are: WPA (TKIP), WPA2 (AES), and WPA2

Mixed. WPA2 (Mixed) support both WPA-PSK(TKIP/AES) and

WPA2-PSK(TKIP/AES). Please make sure your wireless client

supports the cipher you selected.

Pre-shared Key Format

You may select Passphrase (alphanumeric format) or Hex (in the

“A-F”, “a-f” and “0-9” range) to be the Pre-shared Key.

Pre-shared Key

The Pre-shared key is used to authenticate and encrypt data

transmitted in the wireless network. You may create your own

key here for wireless clients to connect to your router.

3.2.2.3 WPA RADIUS

IEEE 802.1x is an authentication protocol. Every user must use a valid account to login to this

wireless router before accessing the wireless LAN. The authentication is processed by a

RADIUS server. This mode only authenticates user by IEEE 802.1x, but it does not encryption

the data during communication.

Select “WPA RADIUS” for the “Encryption” mode if you wish to use WPA RADIUS to encrypt

3.2.4 Advanced Settings

You can set advanced wireless LAN parameters of this router. The parameters include

Authentication Type, Fragment Threshold, RTS Threshold, Beacon Interval, Preamble Type, etc.

It is suggested not to change these parameters unless you know what effect the changes will

have on this router.

Parameters

Description

Fragment Threshold

“Fragment Threshold” specifies the maximum size of packet

during the fragmentation of data to be transmitted. The default

value is 2346.

Page 45 / 80

46

RTS Threshold

When the packet size is smaller than the RTS threshold, the

wireless router will not use the RTS/CTS mechanism to send this

packet.

Beacon Interval

The interval of time that this wireless router broadcast a beacon.

Beacon is used to synchronize the wireless network.

DTIM Period

Set the DTIM period of wireless radio. Do not modify default

value if you don’t know what it is, default value is 3.

Data Rate

Set the wireless data transfer rate to a certain value. Since most

of wireless devices will negotiate with each other and pick a

proper data transfer rate automatically, it’s not necessary to

change this value unless you know what will happen after

modification.

N Data Rate

Same as above, but only for 802.11n clients.

Channel Width

Set channel width of wireless radio. Do not modify default value

if you don’t know what it is, default setting is ‘Auto 20/40 MHz’.

Preamble Type

The “Long Preamble” can provide better wireless LAN

compatibility while the “Short Preamble” can provide better

wireless LAN performance.

Broadcast ESSID

Decide if the wireless router will broadcast its own ESSID or not.

You can hide the ESSID of your wireless router by selecting

“Disable”

CTS Protect

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.

Tx Power

You can set the output power of wireless radio. Unless you are

using this wireless router in a really big space, you may not have

to set output power to 100%. This will enhance security

(malicious / unknown users in distance will not be able to reach

your wireless router).

WMM

The short of Wi-Fi MultiMedia, it will enhance the data transfer

performance of multimedia contents when they are being

transferred over wireless network. The default value is “Disable”.
