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. 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
D-Link 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 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 D-Link 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 D-Link NCP
configuration instead.
