13.6 WLAN Interface General Screen

The following figure provides an example of a wireless network. The wireless network is in the blue circle. Wireless clients (A and B) connect to an access point (AP) to access other devices (such as the printer) or the Internet. Your ZyWALL works as an AP when you install a compatible WLAN card.

Figure 274 Example of a Wireless Network

•Every device in a wireless network must use the same SSID.

The SSID is the name of the wireless network. It stands for Service Set IDentity.

•Different wireless networks in the same area should use different channels.

Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.

•Every wireless client in a wireless network must use security compatible with the AP.

Security stops unauthorized devices from using the wireless network and can protect the information that is sent in the wireless network.
