Lightbulb [TCPDUMP] Connection lost

I'm on Ubuntu – but it's the same on Debian.
I'm using tcpdump in order to track the connection of computers on my private network. At some point, the internet connection of the computers launching the script is lost as well as the targeted computers.

Here's the command line:
Code:
tcpdump -i wlan0 -A src host IP_TARGET

I tried with netsniff-ng, but the issue is the same.

The script that I refer to deviates the connection from the targeted computers to my computer (by sending ARP request) and grep the cookies from the output of tcpdump.
When I get the response packets, I read them and immediately redirect them to the router. Also, the connection is lost sometimes immediately, sometimes after a few minutes.
