Welcome back!
Based on your descriptions (and your previous posts), there is not much you can do. All of your computers are infected with persistent malware, and your network (e.g., router) may also be infected. Based on what you wrote, it appears that the attackers have infected the firmware on your computers. This is how they reconnect even after you wipe a drive and reinstall the operating system from scratch.
Until you replace or fix those devices and learn how to prevent them from becoming reinfected, you are doomed to repeat the same problems over and over, which is what is happening now.
Disconnect from the internet. Disconnect and isolate every device on your network. Fix or replace your home network (router) first. Fix your computers next, and then any other devices (e.g., phones, tablets, etc.) - do them last. Do not connect anything to the new network unless you are sure that it is malware-free. No exceptions!
To fix the computers and most devices, you should back them up first. Treat the backups like infected drives! Next, wipe the drives and replace the firmware with known good firmware from the manufacturer. Download the firmware using a known good network and internet connection. Have your friend write it to a CD ROM or other read-only device. Do not connect any of your devices to your friend's network. Reinstall the operating system from a known good source. Do not connect anything to the new network unless you are sure that it is malware-free. No exceptions!
-> I think you need a technically skilled friend to help you solve these issues.
-> In my opinion, your malware problems are too extensive and complex for someone to help you fix them through an internet forum.
Good luck!
