Chapter 3 - Software Configuration
To set up your wireless interface, you
must first give it an SSID (Service
Set Identifier). The SSID is a unique
identifier attached to packets sent
over WLANs. This identifier
emulates a password when a wireless
device attempts communication on
the WLAN. Because an SSID
distinguishes WLANs from each
other, access points and wireless
devices trying to connect to a WLAN
must use the same SSID.
Select your time zone or the closest
region. Click

to continue.
Quick Setup
To start quick setup, click
Next
to enter the “Quick
Setup” page. Follow the instructions to setup the ASUS
Wireless Router.
Select the connection type. Click
Next
to continue.
Select “No” to enter the information
manually. “Yes” will disable the field.
Click
Next
to continue.

Quick Setup (Cont.)
To adjust other settings, click an item on the menu to
reveal a submenu and follow the instructions to setup
the ASUS Wireless Router. Tips are given when you
move your cursor over each item.
Also, if you want to protect transmitted data, select a middle or high Security
Level.
Medium :
allows only those users with the same WEP key to connect to
this access point and to transmit data using 64bits or 128bits WEP key
encryption.
High:
allows only those users with the same WPA pre-shared key to connect
to this access point and to transmit data using TKIP encryption.
Click
Finish
to continue. You are prompted to save the settings. Click
Save&Restart
to save the settings to the ASUS Wireless Router and enable
the new settings.

Interface
SSID
The SSID is an identification string
of up to 32 ASCII characters that
differentiate one ASUS Wireless
Router AP or Access Point from other
manufacturers. The SSID is also
referred to as the “ESSID” or
“Extended Service Set ID.” You can
use the default SSID and radio
channel unless more than one ASUS
Wireless Router or Access Point is
deployed in the same area. In that
case, you should use a different SSID and radio channel for each ASUS
Wireless Router or Access Point. All ASUS Wireless Routers and ASUS
802.11g/802.11b WLAN client adapters must have the same SSID to allow
a wireless mobile client to roam between the ASUS Wireless Routers . By
default, the SSID is set to “default”.
Channel
The 802.11g and 802.11b specifications supports up to 14 overlapping
channels for radio communication. To minimize interference, configure
each ASUS 802.11g AP to be non-overlapping; select Auto from the Channel
drop-down list to enable the system to select a clear channel during boot up
as your operating channel.
Ensure that ASUS Wireless Routers sharing the same channel (or channels
which are close in number) are as far away from each other as possible,
based on the results of your site survey of the facility. There is a site survey
utility on the ASUS Wireless Router setup CD.

Wireless Mode
This field indicates the 802.11g interface mode. Selecting “Auto” allows
802.11g and 802.11b clients to connect to the ASUS Wireless Router.
Selecting “54g Only” maximizes performance, but prevents 802.11b clients
from connecting to the ASUS Wireless Router. If “54g Protection” is
checked, G-Mode protection of 11g traffic is enabled automatically in the
presence of 11b traffic.
Authentication Method
This field enables you to set different authentication methods which
determine different encryption schemes. The relationship between
Authentication Method, Encryption, Passphrase and WEP Keys is listed in
the following table. If all your clients support WPA, using “WPA-PSK” is
recommended for better security.
WPA Encryption
When “WPA-PSK” authentication method is used, the newly proposed TKIP
(Temporal Key Integrity Protocol) encryption schemes are applied.
TKIP:
TKIP uses an encryption algorithm, which is more stringent than
the WEP algorithm and also uses existing WLAN calculation facilities to
perform encryption operations. TKIP verifies the security configuration
after the encryption keys are determined.
WPA Pre-Shared Key
Selecting “TKIP” in the WPA Encryption, this field is used as a password
to begin the encryption process. Note: 8 to 63 characters are required.

WEP Encryption
Traditional WEP encryption is applied when “Open or Shared Key”, “Shared
Key” authentication methods are selected.
64/128-bit versus 40/104-bit
The following section explains low-level (64-bit) and high-level (128-bit)
WEP Encryption schemes.
64-bit WEP Encryption
64-bit WEP and 40-bit WEP are the same encryption method and can
interoperate in a wireless network. This level of WEP encryption uses a
40-bit (10 Hex character) encryption scheme as a secret key, which is set
by the user, and a 24-bit “Initialization Vector” scheme, which is not under
user control.
Together these two schemes make a 64-bit (40 + 24) encryption scheme.
Some vendors refer to this level of WEP as 40-bit and others refer to this as
64-bit. ASUS WLAN products use the term 64-bit when referring to this
lower
level of encryption.
