No Wi-Fi adapter found Ubuntu 20.04
Solved
Hello, I was quietly on my computer when my cat jumped on the keyboard. Since then, I've been getting this message and I can't connect to the wifi.

On the terminal, I typed the command
rfkill
which gave me access to the information about Bluetooth and Wi-Fi
Id type device soft hard 0 bluetooth. -- Unblocked unblocked 1 wlan. . -- Unblocked blocked 2 wlan. . -- Unblocked blocked 3 bluetooth. -- Unblocked blockedSo I had the Wi-Fi blocked by hardware (I believe). This cannot be unlocked with a command (the soft column can be by typing in the terminal:
rfkill unblock all
For the hardware block, it depends on the PC. Either there is a physical switch, or you need to search online.
For my part, I don't know exactly what I did, but it worked.

As for me, I don't know exactly what I did but it worked.
The command rfkill unblock all is enough to explain why you were blocked and why it unblocked you, so I think you should just keep this command in mind if you encounter the problem again. Thank you for the clarifications, and good luck!

Hello,
If it's a laptop, there is likely a key among the function keys (F1 to F12) that turns the Wi-Fi on/off. Look closely at the symbols on the keys.
If that's not it, then you'll have to wait for someone more knowledgeable than me to come help you.

Hello,
Oh, it’s been a while since we had a problem caused by a cat (we've had some before, such good memories haha :p)
As Barnabé suspects, the only reasonable explanation I see is that your cat accidentally pressed a combination of keys, and the one that could possibly put you in this situation is indeed if your keyboard allows you to turn off the wifi. Sometimes there's a dedicated button for that. What model of laptop are you using?
Good luck!

I managed to find a solution to my problem after two hours of tinkering. It was a hardware issue – a blockage, so to speak.
