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.
