8. Click [OK]. [PRISM Wireless Settings] closes.

You have completed the parameter settings.

* 40 bit and 104 bit encryption is the wireless LAN
equivalent of 64 bit and 128 bit encryption, as set by
Microsoft and wireless LAN manufacturers. This is the
same encryption rate that is used by the Windows XP
operating system, and was selected in order to align it
closer to the wireless LAN standard. For consistency, the
Windows 2000 utilities reflect the same modes.

Outside of wireless LAN environments, encryption is
generally set at either 64 bit or 128 bit. However, the
wireless LAN standard requires that 24 bits be reserved
for fixed data. As a result, the user can only use 40 bits
(64 minus 24) or 104 bits (128 minus 24) for encryption.
This requirement also fixes the number of characters
used for 128 bit encryption to 13 which is calculated as
(13 x 8 bits = 104).

Manually

(Hexadecimal
Input)

Select this to use hexadecimal
character codes to set the encryption
keys (Keys 1 - 4).

Enter a 10-digit value when you have
selected [40 bit]* for the encryption.
Enter a 26-digit value when you have
selected [104 bit]* for encryption.

Select if the network contains a card
that is set with the encryption key
using the character code. Specify the
encryption keys with the same value
used for other wireless LAN cards
that are already set.

ASCII Input

Select to use the ASCII codes to set
encryption keys (Keys 1 - 4). Select
this if network does not contain other
wireless LAN cards that are set with
encryption key using character codes.

Enter a 5-digit value when you have
selected [40 bit]* for the encryption.
Enter a 13-digit value when you have
selected [104 bit]* for encryption.

You can use the following characters:
0 - 9, A - Z, a - z, _ (underscore).

For example, to set “ABC12” for the
encryption key, enter “ABC12.”

Default Key

Click the down arrow, and select a
key from Keys 1 - 4.

P O I N T

When using ADSL (PPPoE) with the infrastructure
network to connect to the Internet, you must change
the computer’s MTU size set. To change MTU size, refer
to the manual that comes with the access point.

P O I N T

More than one network adapter is installed in your
system if more than one [Local Area Connection] entry
is displayed. In this case, select the [Local Area
