I suddenly cannot enable wifi whether booting from a USB installation stick or booting the system from the hard drive. Kubuntu 24.04 Network manager just says "Wireless is disabled". nmcli shows the 2 wireless adapters and their mac addresses but each one says "sw disabled". Followed several suggestions to no avail.

I have followed every suggestion I could find. Odd thing is when I run windows 10 in a virtualbox machine and let it use one of the wireless adapters, wireless works fine in the virtualbox machine. It's as if kubuntu suddenly lost the driver's for the wireless adapters completely. Even booting from installation media does the same thing - no wireless. When I first installed 24.04 it asked me for my wireless security key during installation and it connected immediately.– Fred BeondoCommented Jun 24 at 23:22
