promiscuous mode windows 10 not working

asked 2018-01-06 10:46:06 +0000

Ok so I got wireshark and I want to use moniter mode... which I think is the same as promiscuous mode, i dont know. But my laptop apparantly can't do it. If I was to buy a usb wifi adapter would that help? On capture settings, promiscuous mode is ticked however I am only seeing traffic from my own device... There are definitely others on the wifi. If i should buy a wifi usb adapter which one is best. I am using windows 10.

It is not, but the difference is not easy to spot. On a wired Ethernet card, promiscuous mode switches off a hardware filter preventing unicast packets with destination MAC addresses other than the one of that card from being delivered to the software.

Doing that alone on a wireless card doesn't help much because the radio part won't let such packets through anyway. So a monitor mode means that the wireless interface receives every radio frame on the right radio channel and passes it to the software, regardless whether the frame's destination MAC address is its local one or not. Switching monitoring mode on actually changes much more about the behaviour of the wireless card, but I'm not an expert on that so I'll not talk about details. The biggest difference for the user ...(more)
