Configuration and Management

Figure 14 - Wireless LAN: Radio Channel page

Select either “Auto” (recommended) or a specific channel number from the “Radio channel” drop-down list.

Click Next to proceed.

2.3.2.4 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 W21 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 W21 can obtain access to it.

1/1551-CRH 102 167 Uen Rev E 2008-02-15

Configuration and Management

Figure 15 - Wireless LAN: Network Name (SSID) page

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 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).

If you want to change the preconfigured network name (FWT), type a new name in the “Network name (SSID):” field and also select if the SSID shall be hidden or not.

Click Next to proceed.

2.3.3 Wireless LAN Authentication

All communication on the wireless LAN 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.

20 1/1551-CRH 102 167 Uen Rev E 2008-02-15

Configuration and Management

Figure 16 - Wireless LAN: Authentication page

Select one of the authentication methods from the “Authentication” dropdown list. The available options are as follows:

• None; f you select “None” as authentication method no client configuration is needed but be aware of that the WLAN will now be open without any kind of security.

• WEP (64 bit), WEP (128 bit); 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, WPA2; 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.

Note: Make sure that the operating system(s) and Wireless LAN

interface(s) of the wireless client(s) support the selected authentication method.

Click Next to proceed.
