Mode.
This field determines which data communications protocol will be used. You can select
“g only,” “b only,” or “g and b.” “g only” dedicates the WGX102 to communicating with the
higher bandwidth 802.11g wireless devices exclusively. “b only” dedicates the WGX102 to
communicating with the higher bandwidth 802.11b wireless devices exclusively. The “g and
b” mode provides backward compatibility with the slower 802.11b wireless devices while still
enabling 802.11g communications.
•
Wireless Card Access List.
When the Trusted PCs Only radio button is selected, the
WGX102 checks the MAC address of the wireless station and only allows connections to
computers identified on the trusted computers list.

WEP
WEP offers the following options:
•
Open System
With Open Network Authentication and 64- or 128-bit WEP Data Encryption, the WGX102
does
perform 64- or 128-bit data encryption but
does not
perform any authentication.
•
Shared Key
Shared Key authentication encrypts the SSID and data.
Choose the Encryption Strength (64- or 128-bit data encryption). Manually enter the key
values or enter a word or group of printable characters in the Passphrase box. Manually
entered keys
are
case sensitive but passphrase characters
are not
case sensitive.
Note
: Not all wireless adapter configuration utilities support passphrase key generation.
• Auto
Automatically determines whether Open System or Shared Key should be used.
WPA-PSK
WPA-Pre-shared Key
does
perform authentication, uses 128-bit data encryption and
dynamically changes the encryption keys making it nearly impossible to circumvent.
Enter a word or group of printable characters in the Passphrase box. These characters
are
case sensitive.
Note
: Not all wireless adapter configuration utilities support WPA. Furthermore, client software
is required on the client. Windows XP and Windows 2000 with Service Pack 3 do include the
client software that supports WPA. Nevertheless, the wireless adapter hardware and driver
must also support WPA.
