I’ve noticed killSwitch v6 is not showing the number of network packets sent or received by processes in my computer (the count is stuck at 0). On the other hand, killSwitch v2.4 calculates them properly.
What I can say to you is that I have an integrated Killer E2100 NIC in my computer. It’s not as common as known brands as Realtek and it has a dedicated network processor. It’s drivers aren’t included by default in Windows and currently it has no Linux support. Perhaps killSwitch v6 is not recognizing it properly?
