128-bit WEP Encryption

104-bit WEP and 128-bit WEP are the same encryption method and can

interoperate on a wireless network. This level of WEP encryption uses a

104-bit (26 Hex character) encryption scheme as a secret key which is set

by the user, and a 24-bit “Initialization Vector”, which is not under user

control.

Together these two schemes make a 128-bit (104 + 24) encryption scheme.

Some vendors refer to this level of WEP as 104-bit and others refer to this

as 128-bit. ASUS WLAN products use the term 128-bit when referring to

this

higher

level of encryption.

Passphrase

Selecting “WEP-64bits” or “WEP-128bits” in the Encryption field generates

four WEP keys automatically. A combination of up to 64 letters, numbers,

or symbols is required. Alternatively, leave this field blank and type in four

WEP keys manually.

WEP-64bit key: 10 hexadecimal digits (0~9, a~f, and A~F)

WEP-128bit key: 26 hexadecimal digits (0~9, a~f, and A~F)

Note: The ASUS WLAN family of products uses the same algorithm

to generate WEP keys, eliminating the need for users to remember

passwords and to maintain compatibility between products. How-

ever, using this method to generate WEP keys is not as secure as

manual assignment.

WEP Key

You can set a maximum of four WEP keys. A WEP key is either 10 or 26

hexadecimal digits (0~9, a~f, and A~F) based on whether you select 64bits

or 128bits in the WEP pull-down menu. The ASUS Wireless Router and

ALL of its wireless clients MUST have at least the same default key.

Key Index

The Default Key field lets you specify which of the four encryption keys

you use to transmit data on your wireless LAN. As long as the ASUS

Wireless Router or wireless mobile client with which you are communicating

has the same key in the same position, you can use any of the keys as the

default key. If the ASUS Wireless Router and ALL of its wireless clients

use the same four WEP keys, select “key rotation” to maximize security.

Otherwise, choose one key in common as the default key.

Network Rotation Key Interval

This field specifies the time interval (in seconds) after which a WPA group

key is changed. Enter ‘0’ (zero) to indicate that a periodic key-change is

not required.

Click an item on the menu to reveal a submenu.

Follow the instructions to set up the ASUS

Wireless Router. Tips are displayed when you

move your cursor over an item.

Access Control

Note: Click the “Finish” button to save your new settings and re-

start the ASUS Wireless Router or click “Save” and restart later.

To add security, the ASUS Wireless Router has the ability to only associate

with or not associate with wireless mobile clients that have their MAC

address entered into this page.

The default setting of “Disable” will allow any wireless mobile client to

connect. “Accept” will only allow those entered into this page to connect.

“Reject” will prevent those entered into this page from connecting.

Adding a MAC Address

To add a MAC address, enter the 12 hexadecimal characters into the white box

next to “MAC Address:” and click the

Add

button. The MAC address will be

placed in the control list below. Only a total of 31 MAC addresses can be entered

into this page so determine which will be the lesser; those you wish to accept or

those you wish to reject and click the appropriate “MAC Access Mode”.

Pull down menu items:

Disable (no info required)

Accept (need to input information)

Reject (need to input information)

Advanced

This section allows you to set up

additional parameters for the wireless

router function. We recommend that

you use the default values for all

items in this window.

Hide SSID -

By default, “No” is selected so that wireless mobile users can

see your ASUS Wireless Router’s SSID and join. If “Yes” is selected, your

ASUS Wireless Router will not show in site surveys by wireless mobile

clients and they will have to manually enter your ASUS Wireless Router’s

SSID. If you want to restrict access to “your” ASUS Wireless Router , this

is a simple way to do it but for security reasons, don’t forget to change the

SSID to something other than “default”.

Data Rate (Mbps)

- This field allows you to specify the transmission rate.

Leave on “Auto” to maximize performance versus distance.

Basic Rate Set

- This field indicates the basic rates that wireless clients

must support. Use “1 & 2 Mbps” only when backward compatibility is

needed for some older wireless LAN cards with a maximum bit rate of

2Mbps.

Fragmentation Threshold (256~2346) –

Fragmentation is used to divide

802.11 frames into smaller pieces (fragments) that are sent separately to

the destination. Enable fragmentation by setting a specific packet size

threshold. If there is an excessive number of collisions on the WLAN,

experiment with different fragmentation values to increase the reliability

of frame transmissions. The default value (2346) is recommended for normal

use.

RTS Threshold (0~2347) –

The RTS/CTS (Request to Send/Clear to Send)

function is used to minimize collisions among wireless stations. When

RTS/CTS is enabled, the router refrains from sending a data frame until

another RTS/CTS handshake is completed. Enable RTS/CTS by setting a

specific packet size threshold. The default value (2347) is recommended.

DTIM Interval (1~255) –

DTIM (Delivery Traffic Indication Message) is

a wireless message used to inform clients in Power Saving Mode when the

system should wake up to receive broadcast and multicast messages. Type

the time interval in which the system will broadcast a DTIM for clients in

Power Saving Mode. The default value (3) is recommended.

Beacon Interval (1~65535)

–

This field indicates the time interval in

milliseconds that a system broadcast packet, or beacon, is sent to synchronize

the wireless network. The default value (100 milliseconds) is recommended.
