• 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.
" See the WLAN appendix for more detailed information on WLANs.
10.2 Configuring WLAN
The built-in wireless card is used as part of the LAN by default. You can use the Port Roles
screen (see Figure 132 on page 220) to set a port to be part of the WLAN. Then connect an
access point (AP) to it to extend the ZyWALL’s wireless LAN coverage. See Section 8.13 on
page 187 if you need to configure a 3G connection (a 3G connection is for Internet access
instead of providing a local wireless LAN).
Click NETWORK > WLAN to open the WLAN screen to configure the IP address for
ZyWALL’s WLAN interface, other TCP/IP and DHCP settings.
