After setting up my old Amilo A1630 with the latest Ubuntu, I discovered a severe problem with my internal wireless. I can't unblock the hard block any more and the airplane mode is always on. rfkill doesn't make any difference. The physical button for wireless is on (LED on) and it shouldn't block...
rfkill list gives me: soft blocked: no hard blocked: yes
There's no chance to make any changes in my BIOS, as the wireless isn't listed there.
I really don't know what else to try any more...
Hope anyone of you has a solution for me!
