Was netcut working in your network before? netcut works in normal home WIFI network. if you have
1. extended network,
2. mesh ,
3. IPv6 ,
4. MAC binding.
5. guest network/isolation network
Then netCut might not work. you can try to login into router to disable those option. (most of MAC binding is disable by default)
This is our beta test version, it should fix bug that speed or blocking activity not working at certain PC. Do you want to try and let us know how it goes?
