Point- to-point settings
The configuration of P2P connections involves setting not only the operating
mode but also the station name that the Access Point can connect to. Also,
the role as "Master" or "Slave" is set here.
Along with the settings for the Access Point itself, also to be defined is the
remote site that the Access Point can contact via the P2P connection.

Special wireless LAN parameters for 802.11n
You can use special parameters to adjust the operation of the 802.11n Access
Point to match the application in question. Some of the parameters are con-
cerned with compatibility to the conventional wireless LAN standard, others
with transmission performance.
5.2.1
Compatibility
In principle, 802.11n is backwardly compatible to the previous IEEE 802.11a/
b/g wireless LAN standards even though not all 802.11n functions are sup-
ported in this mode. Compatibility can be allowed or restricted by selecting
the operating mode in the relevant frequency band (2.4 or 5 GHz). In this way
you can allow the corresponding wireless LAN clients to register with the
Access Point.
In the 2.4 GHz band you can allow operation in accordance with 802.1b/
g/n either exclusively or in various mixed modes. When 802.11b is sup-
ported you can also select whether only 11 Mbps mode or the older
2 Mbps are to be supported.
In the 5 GHz band you can choose to allow either greenfield mode
(802.11n only) or mixed operation with 802.11a.
Compatibility is always achieved at the expense of performance. It is
therefore recommended to allow only those modes of operation that
are absolutely necessary for the wireless LAN clients in use.
5.2.2
Performance settings for the wireless LAN module
802.11n provides a number of functions intended to improve wireless LAN
performance, some of which apply to the entire wireless LAN module.
