Wireless LAN

This chapter discusses how to configure the wireless network settings in your NBG420N. See
the appendices for more detailed information about wireless networks.

7.1 Wireless Network Overview

The following figure provides an example of a wireless network.

Figure 59 Example of a Wireless Network

The wireless network is the part in the blue circle. In this wireless network, devices A and B
are called wireless clients. The wireless clients use the access point (AP) to interact with other
devices (such as the printer) or with the Internet. Your NBG420N is the AP.

Every wireless network must follow these basic guidelines.

• Every wireless client in the same wireless network must use the same SSID.

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

• If two wireless networks overlap, they should use different channels.

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