That happened to me many years ago with my second ever Linux computer.
I fumbled around for an hour trying to figure out what was wrong, until
I finally found the switch. So this time that was the first thing I
tried. It turns out that Lenovo decided to save a few pennies and left
out the switch. My P73 has no switch. And Lenovo says the way to turn
it on or off is in the Windows 10/11 taskbar. Sadly, the network icon
in the Xfce4 panel says nothing about wifi; when it's turned off it's
just not there at all.
Fortunately Ubuntu told me the solution:
sudo rfkill unblock wifi; sudo rfkill unblock all
It worked like a charm. I probably needed only the first command,
because I note that Bluetooth is now also turned on. The post also said
that airplane mode can get turned on automatically if there is a delay
in the connection so, bass ackward as that sounds to me - a delay should
restart wifi, not turn it off - it must be why Xubuntu turned it off.
I also question why I must be root to fly in an airplane. Maybe the TSA
is behind this. It sounds more logical that airplanes should emit a
signal that will turn off wireless connections in all computers within
range. Oh wait ... that would cost airplane manufacturers a few
pennies. Never mind.
