Normally, a WiFi network operates in an “infrastructure” type of network. An “infrastructure” type of
network has one or more access points and one or more WiFi clients. The WiFi clients connect to the
access points.
The following figure provides an example of a WiFi network.
Figure 72 Example of a WiFi Network
The WiFi network is the part in the blue circle. In this WiFi network, devices A and B use the access point
(AP) to interact with the other devices (such as the printer) or with the Internet. Your Zyxel Device is the
AP.
Every WiFi network must follow these basic guidelines.
• Every WiFi device in the same WiFi network must use the same SSID.
The SSID is the name of the WiFi network. It stands for Service Set IDentifier.
• If two WiFi networks overlap, they should use a different channel.
Like radio stations or television channels, each WiFi network uses a specific channel, or frequency, to
send and receive information.
• Every WiFi device in the same WiFi network must use security compatible with the AP.
Security stops unauthorized devices from using the WiFi network. It can also protect the information
that is sent in the WiFi network.
