Monitor mode

Mode for a network interface controller

Monitor mode, or RFMON mode, allows a computer with a wireless network interface controller (WNIC) to monitor all traffic received on a wireless channel. Unlike promiscuous mode, which is also used for packet sniffing, monitor mode allows packets to be captured without having to associate with an access point or ad hoc network first. Monitor mode only applies to wireless networks, while promiscuous mode can be used on both wired and wireless networks. Monitor mode is one of the eight modes that 802.11 wireless adapter can operate in: Master, Managed, Ad hoc, Repeater, Mesh, Wi-Fi Direct, TDLS and Monitor mode.
