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.

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.
