2. If the network requires WEP, then the “Data encryption (WEP enabled)”
check box is selected by default in Wireless Network Properties. Select
the “The key is provided for me automatically” check box if the WEP key
is automatically provided for you. The driver will then use the Default
Encryption key from the current Alphanetworks NCP configuration profile
irrespective of the network name. You may choose to enter the WEP key
by clearing this check box and manually entering the network key and
key length. Note that 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 Alphanetworks 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 Alphanetworks NCP configuration
instead.
