A couple of days ago, my wifi suddenly shut off. I tried logging
out and back in. Then, I tried rebooting. No joy.

I tried to bring it up with nmcli:

user@host$ sudo nmcli radio wifi on
user@host$

After doing so, this message appears in syslog:

Apr 12 14:29:07 host NetworkManager[946]: <info> [1649791747.4725] audit: op="radio-control" arg="wireless-enabled:1" pid=25176 uid=0 result="success"

However, NetworkManager appears to have a different definition of
"success" than I do, because:

user@host$ nmcli general status
STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN
connected full enabled disabled enabled disabled
user@host$

My wi-fi is still shut off.

Any ideas on how to recover? It's a fairly important (to me) box,
and I don't like having it in the cellar so that I can plug it
in directly to the router.

Thanks.

What happens if you boot up a live linux off say USB?

If this is a laptop, then it might have some kind of kb switch, but the
data you've shown look like that is ON.

If you know the name of your wifi, you can

ifconfig wlan0 up

....where wlan0 should be whatever is the correct name.

But for me, booting a different system which is likely to work is better
for me than trying to fight w/ something wrong w/ my system.

And, I have had situations in which the easiest way for me to get my
network working again was to boot up a Windows on the same hardware and
use its troubleshooter.

No sooner did I post this than I discovered that Dell, in their
infinite wisdom, decided to put a switch on the side that can
turn off the wifi.

Sorry for the false alarm.

What does rfkill list say?

First thing that I thought of was that I had fat-fingered one of the
F-keys. But, I looked at them, and none had any antenna logos. Unlike
my other two Dells.

As I noted cross-thread, it turns out that there's a slider switch on
the side. New ways to fat-finger.

I'll keep that in mind, since I've never liked having to settle for
pointy-clicky ways to maybe enable/disable. I only found out about
nmcli earlier this year, and was glad of it. However, there's not much
it can do to override a hardware switch.

Thanks.

Not an option for me, as I don't have Windows, and never knew how
to do any trouble-shooting with it anyhow.

Boy, I wish that I'd known that command on Sunday! It nicely
distinguishes between "hard blocked" and "soft blocked". And,
as I noted cross-thread, my problem turned out to be a
hardware switch carefully hidden on the side.

Useful info , it appears my Dell E6330 also has such a switch ...hardly
visible.Never looked for it before .
BTW , the above laptop runs LMDE5 comfortably ....waiting for LM21 .
