In the 5 -GHz band, the automatic search for vacant WLAN channels can lead
to several simultaneous test transmissions from multiple access points, with
the result that they do not find each other. This stalemate situation can be
avoided with the appropriate "Channel selection scheme":
Master:
This access point takes over the leadership when selecting a free
WLAN channel.
Slave:
All other access points will search for a channel until they have
found a transmitting Master.
Thus it is recommended for the 5 GHz band that one central access point
should be configured as 'Master' and all other point-to-point partners should
be configured as 'Slave'. In the 2.4 GHz band, too, this setting simplifies the
establishment of point-to-point connections if the automatic channel search
is activated.
It is imperative that the channel selection scheme is configured cor-
rectly if the point-to-point connections are to be encrypted with
802.11i/WPA (a master as authentication server and a slave as client).

Configuration of P2P connections
In the configuration of point-to-point connections, entries have to be made
for the point-to-point operation mode and the channel selection scheme,
along with the MAC addresses or station names of the remote sites.
Configuration with
LANconfig
For configuration with LANconfig you will find the settings for P2P connec-
tions under the configuration area 'Interfaces' on the 'Wireless LAN' tab.
The configuration of the P2P connections can also be carried out with
the WLAN Wizards in LANconfig.
