How to get Linux distribution name and version in.If there was such program intentionally running or bridged networking for hardware virtualization, the promiscuous mode message might be simply ignored. Confirmed with Wireshark 2.0.1 on MacOSX 10.11.5 today.

To see packets from other computers, you need to run with sudo. When you run wireshark without sudo, it runs no problem but only shows you packets from/to your computer.

not all Wi-Fi cards support promiscuous and monitor modeįurther reading: Promiscuous mode (Wikipedia).

monitor mode does not make sense (and so does not exist) for LAN cards.

it can decrypt packets to/from other nodes in secured networks.

SSID filtering is switched off => it can receive packets from any AP within its range.

usually NOT connected to the Access Point (depends on the adapter and its driver) => it does not transmit any packets.

it translates Wi-Fi data frames into wired Ethernet-style frames (IEEE 802.3) so they look like Ethernet frames captured on the LAN interface working in promiscuous mode.

it can't decrypt packets to/from other nodes in secured (WEP, WPA.) networks.

MAC filtering is switched off => it can receive packets destined for any MAC address.

SSID filtering is switched on => it can receive packets only from AP it is associated with (it receives radio packets from all APs but forwards to the upper layers only those from that particular AP).
