encryption settings are explained in 

Here are some concepts and guidelines regarding the SSID:

A basic service set (BSS) is a group of wireless devices and a single wireless access 

point, all using the same security profile or service set identifier (BSSID). The actual 
identifier in the BSSID is the MAC address of the wireless radio. (A wireless radio can 
have multiple MAC addresses, one for each security profile.)

An extended service set (ESS) is a group of wireless devices, all using the same identifier 

(ESSID).

Different devices within an ESS can use different channels. To reduce interference, 

adjacent devices should use different channels. 

Roaming is the ability of wireless devices to connect wirelessly when they physically 

move from one BSS to another one within the same ESS. The wireless device 
automatically changes to the wireless access point with the least interference or best 
performance.

Before You Change the SSID, WEP, and WPA Settings

For a new wireless network, print or copy the following form and fill in the settings. For an 
existing wireless network, the network administrator can provide this information. Be sure to 
set the Country/Region correctly as the first step.

Store this information in a safe place:

The service set identifier (SSID) identifies the wireless local area network. You can 
customize it by using up to 32 alphanumeric characters. Write your SSID on the line. 

SSID: ___________________________________ 

The SSID in the wireless access point is the SSID you configure on the wireless adapter 
card. All wireless nodes in the same network need to be configured with the same SSID.

Choose the key size by circling one: 64, 128, or 256 bits.
Choose the key format by circling one: ASCII or HEX.
Choose the authentication type by circling one: Open or Shared.

Passphrase: ___________________________________ 

Note: If you select shared key, the other devices in the network will not connect unless 
they are set to shared key and have the same keys in the same positions as those in the 
security profile on the wireless module.

Record the WPA-PSK passphrase:
