 To get it to work as an access point with this configuration you will need
 to set up a DHCP server to work with that network. You can - of course - also
 bridge the Wireless interface with any configured bridge
 (:ref:`bridge-interface`) on the system.
 
+WiFi-6(e) - 802.11ax
+====================
+
+The following examples will show valid configurations for WiFi-6 (2.4GHz) 
+and WiFi-6e (6GHz) Access-Points with the following characteristics:
+
+* Network ID (SSID) ``test.ax``
+* WPA passphrase ``super-dooper-secure-passphrase``
+* Use 802.11ax protocol
+* Wireless channel ``11`` for 2.4GHz
+* Wireless channel ``5`` for 6GHz 
+
+
+Example Configuration: WiFi-6 at 2.4GHz
+---------------------------------------
+
+You may expect real throughputs around 10MBytes/s or higher in crowded areas.

+You may expect real throughputs around 50MBytes/s to 150MBytes/s, 
+depending on obstructions by walls, water, metal or other materials
+with high electro-magnetic dampening at 6GHz. Best results are achieved 
+with the AP being in the same room and in line-of-sight.
