Wi-Fi networks are on a shared medium, unlike switched Ethernet networks, so you'll be able to capture all the packets however, most Wi-Fi networks are 'protected', using WEP or WPA/WPA2, meaning the traffic is encrypted, and you'll need a tool that can decrypt that traffic (such as Wireshark) and the password for the network and, for modern networks using WPA or WPA2, the initial connecting-to-the-network handshake for each device whose traffic you want to decrypt. Promiscuous mode is a mode your network adapter works in, in which it hands packets to the host no matter what the destination MAC address, but if the switch won't even send you the packets that aren't broadcast or multicast or addressed to you, there's nothing your adapter can do.įor monitor mode, which is a Wi-Fi feature (it doesn't exist on wired adapters), whether you are 'disconnected' in monitor mode, in the sense that you will no longer be connected to the network, depends on your network adapter, OS, and driver. However, Ethernet doesn't generally work the way it originally did, and promiscuous mode doesn't work as well as it used to. stuff.įor promiscuous mode, which is mainly a wired-network feature (it doesn't work well on Wi-Fi adapters), you won't be 'disconnected' in the sense that you will no longer be connected to the network.

But when i go to promiscous or monitor mode i will be disconnected from my router and cant see any traffic except dhcp and such stuff.
