2. In Wireless Network Properties, the “This is a computer-to-computer (ad
hoc) network; wireless access points are not used” check box is selected by
default. You may choose to enable WEP by selecting the “Data encryption
(WEP enabled)” check box and the “Network Authentication (Shared
mode)” check box.
3. Select the “The key is provided for me automatically” check box if the
shared key is automatically provided for you. The driver will then use the
Default Encryption key from the current Atheros NCP configuration
profile irrespective of the network name.
You may choose to enter the shared key by clearing this check box and
enter the key and key length manually.
NOTE: The key format must be hexadecimal digits and the key length is
limited to 104-bit in Windows XP as opposed to 128-bit key supported by
Atheros NDIS driver in the NCP configuration interface. If the network
that you are connecting to requires 128-bit WEP key then it is
recommended that you disable Windows XP automatic wireless network
configuration and use Atheros NCP configuration instead.
