15.4 Channel Usage
The Channel Usage screen shows whether a channel is used by another wireless network or
not. If a channel is being used, you should select a channel removed from it by five channels to
completely avoid overlap.
Click MAINTENANCE and then the Channel Usage tab to display the screen shown next.
Wait a moment while the ZyXEL Device compiles the information.

15.5 F/W Upload Screen
Find firmware at www.zyxel.com in a file that (usually) uses the system model name with a
"*.bin" extension, for example "NWA-3100.bin". The upload process uses HTTP (Hypertext
Transfer Protocol) and may take up to two minutes. After a successful upload, the system will
reboot. See the Firmware and Configuration File Maintenance chapter for upgrading firmware
using FTP/TFTP commands.

LABEL DESCRIPTION
SSID This is the Service Set IDentification name of the AP in an Infrastructure
wireless network or wireless station in an Ad-Hoc wireless network. For our
purposes, we define an Infrastructure network as a wireless network that uses
an AP and an Ad-Hoc network (also known as Independent Basic Service Set
(IBSS)) as one that doesn’t. See the Wireless Configuration and Roaming
chapter for more information on basic service sets (BSS) and extended service
sets (ESS).
MAC Address This field displays the MAC address of the AP in an Infrastructure wireless
network. It is randomly generated (so ignore it) in an Ad-Hoc wireless network.
Channel This is the index number of the channel currently used by the associated AP in
an Infrastructure wireless network or wireless station in an Ad-Hoc wireless
network.
Signal This field displays the strength of the AP’s signal. If you must choose a channel
that’s currently in use, choose one with low signal strength for minimum
interference.
Network Mode “Network mode” in this screen refers to your wireless LAN infrastructure (refer
to the Wireless LAN chapter) and security setup.
