6. Select the country of operation for the terminal from the Country: drop-down list.
This ensures the terminal is using country code information compatible with the
country code data used by the associated AP. Select International if using the
terminal with a non-Symbol AP or a pre AP 4131 model.
7. Select the Encryption tab to set the terminal profile security level.
The terminal supports Open System (no encryption), 40-bit Shared Key, 128-bit
Shared Key, Kerberos and LEAP encryption algorithms. The absence of a physical
connection makes wireless links vulnerable to information theft. Encryption is an
efficient method of preventing data theft and improving data security.
The AP and the terminal must use the same encryption algorithm to associate and
transmit data. If an AP is set to Open System and an adapter is set to 40-bit or 128-
bit, no association takes place. Similarly, if an adapter is set to Open System and
an AP is set to 40-bit or 128-bit, no association takes place.
If an AP is set to 40-bit and a terminal is set to 128-bit the terminal can associate
with the AP, but no data transmission and reception can take place.
8. Select one of the following Encryption options from the Algorithm: drop-down list:
Open System
(no encryption)
40-bit Shared
Key
10-8
Figure 10-4. Encryption Tab
Use the Open System option as the default setting when no
data packet encryption is needed over the network. Selecting
Open System provides no security for data being transmitted
over the network.
Select 40-bit encryption and enter a 10-digit hex encryption
key. Tap Reset Keys to set the encryption key to the default
values.
