+**Some notes concerning multiap configuration files.**   
+While preparing the */etc/config/wireless* configuration, please note that some options may be changed during autoconfiguration proces. 
+Such options are wps_pushbutton and hidden of wifi-iface section. Actions taken and final value of those options depends mainly on type
+of multi_ap interface (value of option multi_ap in current wifi-iface section).  
+
+For backhaul interfaces where 
+```  
+option multi_ap '1'
+```
+following rules apply:
+* 'hidden' option when provided stays as it is,  
+* if 'hidden' option is not provided in that wifi-iface section, it is set to hidden=1 by adding  
+```
+option hidden '1'  
+```

+For fronthaul and combined interfaces where  
+```
+option multi_ap '2'

+following rules apply:  
+* 'wps_pushbutton' option when provided stays as it is,
+* if 'wps_pushbutton' option is not provided in that wifi-iface section, it is set to wps_pushbutton=1 by adding  
+```
+option wps_pushbutton '1'

+Additional rule apply when traffic separation is enabled in */etc/config/mapcontroller* by

+option enable_ts '1'
+```
+in controller section of that config.

+Additional rule concerns guest network which should be added in */etc/config/mapcontroller* file always after already existing networks.
+This rule is that guest network will always have wps_pushbutton disabled by  
+```
+option wps_pushbutton '0'
+```
+always placed in that wifi-iface section.
