Hacking, coding, IP addresses

Help my hard drive has a bypass that controls my settings and my control panel, which then allow access to all my devices. I got rid of my computer and changed WiFi and Internet connection. My router was not used. My ex is a code writer and he should have repaired it, then my whole network is off. He bought a new router and it's also undecir badewste and I said it was my Rx. It never stops.
