Wifi module mode:

managed mode : working as a wireless station master mode : working as an access point monitor mode : working as a sniffer

ihost mode

base mode : BAS(Broadband Access Server) only plus mode : BAS and Hotspot

ihost & wifi

1, ihost in base mode : wifi chipset works in monitor mode (interface mon0) 2, ihost in plus mode : wifi chipset works in master mode (interface wlan0); there is a virtual interface (mon.wlan0) created by hotspot service (hostapd), packet sniffing is carried out on mon.wlan0

both monitor mode and master mode are needed; with managed mode as default

master mode only is acceptable : hotspot service starts up and keeps hidden from user. we can use mon.wlan0 for packet capture. deficiencies：1, channel occupied but not used; 2, mon.wlan0 seems less stable than mon0. it's a work-around anyway.
