Ericsson W21 2.6.7 WLAN Security

Configuration and Management

The following settings concerning the network name are displayed and can

be modified on the Wireless LAN page:

Table 14 - Network name description

Text Description

The network name (SSID) of the WLAN.

Network name (SSID)

The network name is case-sensitive

(distinguish between uppercase and

lowercase letters) and can be changed to

any combination of numbers (0-9), letters

(a-z), and hyphens (-) with a maximum

length of 32 characters.

If “Enable SSID broadcast” is checked, the

AP (Ericsson W21) continuously

broadcasts the network name and any

nearby wireless device(s) will find it when

scanning the air.

Enable SSID broadcast

If the checkbox is cleared, the network

name will be hidden and in this case the

name has to be provided manually to every

wireless device where access is to be

granted.

To change settings for the Network Name (SSID), type the new values in

the corresponding fields and click Apply to save the settings.

2.6.7 WLAN Security

All communication on the wireless network can be protected using different

authentication and encryption methods. The most common is to encrypt the

WLAN using an encryption method such as WEP, WPA and WPA2.

Which authentication and encryption method that should be used depends

on what is supported by the connected wireless client(s).

Note: Each wireless device must be configured to use exactly the same

security mode and key/passphrase as the Ericsson W21 or they

will not be able to connect.

In the “Authentication method” list you select which type of authentication/

encryption you want to use for your WLAN. The following subsections

describe the authentication methods supported by the Ericsson W21.
