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.
Based  on  your  site  survey  of  your  network  facility,  make  sure  that  all  the 
ASUS 802.11g APs sharing the same channel, or channels in close number 
frequency, are located far from each other as possible. You can use the site 
survey utility from the support CD. Refer to 3.7.2 Site Survey (AP SCAN) 
for details.
Wireless Mode
This  field  indicates  the  802.11g  interface  mode.  Selecting  “Auto”  allows 
802.11g and 802.11b clients to connect to the ASUS 802.11g AP. Selecting 
“54g  Only”  maximizes  performance,  but  prevents  802.11b  clients  from 
connecting  to  the  ASUS  802.11g  AP.  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 relationships among Authentication Method, 
WPA Encryption, WPA Pre-Shared Key, WEP Encryption, Passphrase, and 
WEP Keys are listed in the following table. If all your clients support WPA, 
using “WPA-PSK” is recommended for better security.
Authentication WPA / WEP WPA Pre-Shared Key Method  Encryption Passphrase  WEP Key 1–
Open or shared key  None Not required  Not required   WEP (64 bits) 1–64 characters  10 hex   WEP (128 bits) 1–64 characters  26 hex

WPA Encryption
When  “WPA-PSK”  authentication  method  is  used,  the  newly  proposed 
TKIP  (Temporal  Key  Integrity  Protocol)  or AES  encryption  schemes  are 
applied.
WPA Pre-Shared Key
Select  “TKIP”  or  “AES”  in  the  WPA  Encryption,  this  field  is  used  as  a 
password to begin the encryption process. 8 to 63 characters are require\
d.
WEP Encryption
When  “Open  or  Shared  Key”,  “Shared  Key”  or  “Radius  with  802.1x” 
authentication methods are selected, traditional WEP encrption is applied.
NOTE: When “WPA” or “WPA-PSK” authentication methods are se-
lected, you still can set WEP encryption for those clients that do not 
support WPA/WPA-PSK. Please note that Key Index for WEP key is 
limited to 2 or 3 when both WPA and WEP encryption are supported 
at the same time.
6/128-bit versus 0/10-bit
The following section explains low-level (64-bit) and high-level (128-bit) 
WEP Encryption schemes:
6-bit WEP Encryption
64-bit  WEP  and  40-bit  WEP  are  the  same  encryption  methods  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.
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.

Access Point

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
Select  “WEP-64bits”  or  “WEP-128bits”  in  the  Encryption  field,  and  the 
Access Point 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. It eliminates the need for users to remember 
passwords and maintains compatibility between products. But, this 
method  to  generate  WEP  keys  is  not  as  secure  as  manual  assign-
ment.
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 64-bits 
or 128-bits in the WEP pull-down menu. The ASUS 802.11g AP 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 to 
use to transmit data on your wireless LAN. As long as the ASUS 802.11g AP 
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 802.11g AP 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.

3.7.6  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. 
You may also setup operation modes 
(AP or WDS, Station or URE) in this 
window aside from the Quick Setup 
screen.
Hide  SSID  -“No”  is  the  default  option  so  that  wireless  mobile  users  can 
see your ASUS 802.11g AP’s SSID and associate with your Access Point. 
If you select “Yes”, your ASUS 802.11g AP will not show in site surveys 
by wireless mobile clients and they will have to manually enter your ASUS 
802.11g AP’s  SSID.  To  restrict  access  to  your ASUS  802.11g AP  ,  select 
“Yes”. For security reasons, change the SSID other than the default SSI\
D.
Set AP Isolated - Selecting Yes to prevent wireless client from communicating 
with each other.
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.  Set  a  specific  packet  size  threshold  to  enable  fragmentation. 
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.  Set  a  specific  packet  size 
threshold to enable RTS/CTS. The default value (2347) is recommended.
