Security Measures Since wireless LAN provides data transfer using electric waves instead of LAN cables between communicating devices, a third party can illegally access to and monitor the transmitted information. The following security measures reduce opportunities to receive the threats. Use a combination of the following measures for more secure communications. See Notice of Security with Wireless Devices section on page xiv. Authentication The following may help you receive less illegal access. • SSID (Service Set Identifier) "SSID" is a common network name. A SSID acts as a password that is shared with all connecting wireless users, resulting in preventing access by any device that 5 does not have the SSID. Set a same SSID on your computer and access point. Since this may be equivalent to no security, rely on a combination of the SSID and WEP keys. (For details on configuration of an access points, refer to its manual.) • MAC (Media Access Control) address filtering MAC addresses are unique addresses on the network, which are allocated to the computer's network interface cards. An access point allows access by a device only if that device's MAC address matches an address in an authentication list used by the access point. Register your MAC address with your access point. (For more information, refer to the manual of your access point.) • For other security measures, refer to the manual of your access point. • To find the MAC address of your computer: 1. Click start - All Programs - Accessories - Command Prompt. 2. Enter ipconfig/all; then, press Enter. 3. Find the numbers of Physical Address in Ethernet adapter Local Area Connection section. They are the MAC address of your computer. 4. Type exit; then, press Enter. 5-6

between communicating devices, a third party can illegally access to and monitor the
transmitted information. The following security measures reduce opportunities to

Authentication
The following may help you receive less illegal access.
•
SSID (Service Set Identifier)
“SSID” is a common network name. A SSID acts as a password that is shared with
all connecting wireless users, resulting in preventing access by any device that
does not have the SSID.
Set a same SSID on your computer and access point.
Since this may be equivalent to no security, rely on a combination of the SSID and
WEP keys. (For details on configuration of an access points, refer to its manual.)
•
MAC (Media Access Control) address filtering
MAC addresses are unique addresses on the network, which are allocated to the
computer’s network interface cards. An access point allows access by a device
only if that device’s MAC address matches an address in an authentication list
used by the access point. Register your MAC address with your access point. (For
more information, refer to the manual of your access point.)
•
For other security measures, refer to the manual of your access point.
