2.3.2 Wireless LAN Access
The second part of the Configuration Wizard includes configuration of the
Wireless LAN (WLAN). A Wireless LAN is a local network that
communicates through wireless connections.
Note: The wireless setup typically requires configuration of both the
Ericsson W20 and the wireless clients. For more information about
configuring wireless clients, see
Access Point
The Ericsson W20 is a WLAN Access Point (AP) for the local network
providing the wireless client(s) with Internet and LAN access.

Region
To make sure the Ericsson W20 operates on correct radio frequencies
according to local regulations, you have to state in which region you reside.
After this you cannot select any radio channel that would be against the
regulations.

Configuration and Management
Channel Selection
The maximum number of regulatory channels to use for wireless
communication is 13. Available channels depend on local regulations. You
can select one of the available channels yourself, or let the Ericsson W20
automatically select a channel.
Figure 13 Wireless LAN: Radio Channel page
Select either Auto (recommended) or a channel number from the Radio
channel list on the Wireless LAN: Radio Channel page. Click Next to
proceed.
Network Name
All devices on the local wireless network share a common Service Set
IDentifier (SSID) or network name. This name is required to establish
connection between the Ericsson W20 and the wireless client(s), and to
distinguish the wireless network from any other(s) that may be in use
nearby. Only devices configured with the same network name as the one
set on the Ericsson W20 can obtain access to it.
14 1/1551-CRH 102 167 Uen Rev A 2006-09-07
Configuration and Management
Figure 14 Wireless LAN: Network Name (SSID) page
The default network name can be changed to any combination of numbers
(0 – 9), letters (a – z), and hyphens (-) with a maximum length of 127
characters. Type the new name in the Network name (SSID) field on the
Wireless LAN: Network Name (SSID) page.
If the SSID broadcast option is enabled, your local wireless device(s) will
find the network name when scanning the air. If the option is disabled, the
network name is hidden and has to be manually provided to the wireless
device(s). To disable network name broadcast, clear the Enable SSID
broadcast check box on the Wireless LAN: Network Name (SSID) page.
Click Next to proceed.
Authentication
The wireless data transmissions can be protected from potential intruders
and eavesdroppers through standard authentication and encryption
methods. Authentication is used to restrict access to the wireless network.
Encryption is the translation of data into a form that cannot be easily
understood by unauthorized users. The encrypted data can only be sent
and received by users with access to a private encryption key.
WEP (Wired Equivalent Privacy) is considered to be a low security option.
WEP encrypted data is translated into blocks of either 64 bits length or 128
bits length.
WPA (Wi-Fi Protected Access) and its successor WPA2 are the most
reliable security options. WPA encryption uses the Temporal Key Integrity
Protocol (TKIP) while WPA2 encryption follows the Advanced Encryption
Standard (AES). AES offers a higher level of security and is approved for
sensitive corporate and government data transmission.

If you select Open, the last page of the wizard, where you can review and
confirm your settings, is displayed. Check the information on this page and
click Finish to confirm the settings.
