Configuration Using Web Based Management and the Command Line Interface
If signals of a primary user are found on the configured or selected channel, the
access point follows the procedure outlined below:
● Auto channel select = enabled
With automatic channel select, the access point changes to a different channel
and repeats the availability check for this channel.
● Auto channel select = disabled
If the channel is fixed in the configuration, the access point changes to the
configured alternative channel and repeats the availability check for this
channel. If a primary user (for example radar) is discovered on the alternative
channel, a further channel is selected at random.
Communication with clients is started only when no primary user has been
discovered on the selected channel for one minute.

case signals of a primary user are found on the main channel.
Make sure that the alternative channel is not being used by other access points.
In the IEEE 802.11h transmission mode, it is not practical to select the WDS mode
at the same time. In WDS mode, all SCALANCE W78x devices must use the same
channel. If a signal from a primary user is detected by an AP, the channel is
changed automatically and the existing connection is then terminated.
