I have recently installed OPNsense on my old CPU and tried to use it as an internet router. Initially after installation the net was not working, so I connected the LAN cable and used a guide on youtube to set up everything from 192.168.1.1. However, the guide was incredibly complex and I left it halfway. Then in order to follow a basic guide I connected my CPU to a monitor and chose the restore defaults option. It restarted and then I tried assigning WAN interface, where is said to press a to automatically detect WAN. I pressed it and then it stuck. I unplugged it and then turned it on again, but since then, there has been no output through the VGA and no sound to confirm opnsense is on, although the CPU is running. What should I do?
