In DarkMatter 4.7 B2 comes the default kernel 4.14.15 PhoenixOS in which I use the ExpressVPN application and when verifying the IP address, DNS leaks and WebRTC leaks these are correctly applied, but there is a problem and it is that in this kernel there are wifi problems and the wifi is disconnected very frequently. They have recommended me to change the kernel and I have tried several kernels and for example the kernel 4.19.160 Benares 3.0 seems that if it solves the disconnection of wifi, but I have tried the VPN connection with this kernel and although the application says it is connected to the VPN network When performing the IP, DNS and webRTC tests, these are erroneous as there is some kind of problem which causes that even if it says connected, the changes are not applied and the VPN connection is not really effective. I also check the IP using a web browser and it has not been changed. This happens with all kernels tested except kernel 4.14.15 PhoenixOS, which is the only one that does the VPN connection. I do not know if there is any solution for this, if there is, I would be very grateful if someone would help me and if not, I hope they can solve this problem for the future. Greetings and thanks!
