7.1.2 What You Should KnowEvery 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.
• Every wireless client in the same wireless network must use security compatible
with the AP.
Security stops unauthorized devices from using the wireless network. It can also
protect the information that is sent in the wireless network.
Wireless Security Overview
The following sections introduce different types of wireless security you can set up
in the wireless network.
SSID
Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area.
You can hide the SSID instead, in which case the AP does not broadcast the SSID.
In addition, you should change the default SSID to something that is difficult to
guess.
