Using the Windows Utility
Authentication Mode
Encryption Method
You MUST select the option to match the Wireless LAN you
wish to join. The available options are:
•
Open - Broadcast signals are not encrypted. This method can
be used only with no encryption or with WEP.
•
Shared Key - Broadcast signals are encrypted using WEP.
This method can only be used with WEP.
•
Auto Switch - This is another WEP system; it will select
either Open System or Shared Key as required.
•
WPA-PSK - PSK means "Pre-shared Key". You must enter
this Passphrase value; it is used for both authentication and
encryption.
•
WPA2-PSK - This is a further development of WPA-PSK,
and offers even greater security. You must enter this
Passphrase value; it is used for both authentication and encryption.
•
WPA-Radius - This version of WPA requires a Radius
Server on your LAN to provide the client authentication according to the 802.1x standard. Data transmissions are
encrypted using the WPA standard.
•
WPA2-Radius - This version of WPA2 requires a Radius
Server on your LAN to provide the client authentication according to the 802.1x standard. Data transmissions are
encrypted using the WPA2 standard.
The available options depend on the Authentication method
selected above. The possible options are:
•
Security Off - No data encryption is used.
•
WEP - If selected, you must enter the WEP data shown
below. This WEP data must match the Access Point or other
Wireless stations.
•
AES, TKIP - These options are available with WPA-PSK,
WPA2-PSK, WPA-Radius and WPA2-Radius. Select the
correct option.
Create with
Passphrase
Enable this check box and enter a word or group of printable
characters in the Passphrase box, select the desired encryption to
automatically configure the WEP Key.
Enter Key Manually
Enable this check box and select the desired key in the dropdown list. Then enter the key values you wish to use and select
the desired encryption. Other stations must have matching key
values.
Passphrase
For WPA-PSK and WPA2-PSK modes, you need to enter the
desired value (8~63 characters). Data is encrypted using a 256Bit
key derived from this key. Other Wireless Stations must use the
same key.
Confirm
For WPA-PSK and WPA2-PSK modes, re-enter the value in this
field.

Appendix B
About Wireless LANs
This Appendix provides some background information about using Wireless
LANs (WLANs).
Modes
Wireless LANs can work in either of two (2) modes:
•
Ad-hoc
•
Infrastructure
Ad-hoc Mode
Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Stations (e.g. notebook PCs with wireless cards) communicate directly with each other.
Infrastructure Mode
In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations
(e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations
can then access all LAN resources.
Access Points can only function in "Infrastructure" mode,
and can communicate only with Wireless Stations which are
set to "Infrastructure" mode.
BSS/ESS
BSS
A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a
Basic Service Set (BSS).
Using the same SSID is essential. Devices with different SSIDs are unable to communicate
with each other.
ESS
A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form
an Extended Service Set (ESS).
Different Access Points within an ESS can use different Channels. In fact, to reduce interference, it is recommended that adjacent Access Points SHOULD use different channels.
As Wireless Stations are physically moved through the area covered by an ESS, they will
automatically change to the Access Point which has the least interference or best performance.
This capability is called Roaming. (Access Points do not have or require Roaming capabilities.)
18
Appendix B - About Wireless LANs
Channels
The Wireless Channel sets the radio frequency used for communication.
•
Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA
and Canada, 11 channels are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference.
•
In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an
Access Point. If more than one Access Point can be used, the one with the strongest signal
is used. (This can only happen within an ESS.)
•
If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the
same Channel. However, most Wireless stations will still scan all Channels to see if there
is an existing "Ad-hoc" group they can join.
WEP & WPA-PSK
Both WEP and WPA-PSK are standards for encrypting data before it is transmitted.
This is desirable because it is impossible to prevent snoopers from receiving any data which is
transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless
unless the receiver can decrypt it.
WPA-PSK is a later standard than WEP, and is more secure.
Wireless LAN Configuration
To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point
must use the same settings, as follows:
Mode
On client Wireless Stations, the mode must be set to "Infrastructure".
(The Access Point is always in "Infrastructure" mode.)
SSID (ESSID)
Wireless Stations should use the same SSID (ESSID) as the Access
Point they wish to connect to. Alternatively, the SSID can be set to "any"
or null (blank) to allow connection to any Access Point.
Security
The Wireless Stations and the Access Point must use the same settings
for Wireless security (Disabled, WEP, WPA-PSK)
WEP - If WEP is used, the WEP Key must be the same on the Wireless
Stations and the Access Point. WEP Authentication ("Open System" or
"Shared Key") must also be the same, unless the Access Point supports
both methods simultaneously.
WPA-PSK - If using WPA-PSK, all wireless stations and the Access
Point must use the same key and encryption method.
