the Wireless LAN module will automatically start operation at the
channel identified by the Wireless LAN Access Point. When

switch to another channel if required.

the factory-set default channel (printed in bold), unless the LAN
Administrator selected a different channel when configuring the
Wireless LAN Access Point device.
