I was having trouble updating a laptop I hadn't used in a while. Someone suggested that I do a fresh install I did however now my WiFi is not working. The WiFi worked on the liveUSB.
For some reason, my screen stays blank between the manufacturer's splash screen and the login screen, so I can't access Grub after installing a new kernel. According to the rkill command (I think), the WiFi is hard blocked. I have pressed the wifi button on the computer several times but it didn't turn on.
