[SOLVED] WIFI Card disabled all of a sudden

banderas20 · 07-17-2023, 05:04 AM

Hi!

I have a Dell XPS Laptop with Ubuntu 20.04 installed. Recently, the wifi adapter stopped working all of a sudden, without any update.

The network manager shows "No Wifi Adapter available".

Code:

systemctl status networkmanager

shows:

Code:

device (wlp59s0): state change: unmanaged -> unavailable (reason 'managed', sys-iface-state: 'external'
Error: failed to open /run/network/ifstate

I don't have any /run/network directory. Neither /etc/network/interfaces file

If I run

Code:

ip a

, the device appears.

If I run

Code:

nmcli

, it shows:

Code:

wlp59s:unavailable
iwlwifi: <MAC> , sw disabled, hw, mtu 1500.

I'm guessing I might have disabled it by mistake with a keyboard shortcut, but I can't get it back to work. II just can toggle the airplane mode on and off.

Any ideas?

Thanks!

It worked!

BTW, to understand what happened. Which was the issue? Why did it turn off?

Thanks a million!

TBH I wouldn't worry about it as long as you remember that command.

I have a cheap old lenovo netbook where the airplane mode key sw blocks wifi when used, yet my ThinkPads will hw block with the wifi key.

It may be the desktop, the ACPI implementation, who knows? See also rfkill, give you Bluetooth control too.

Yeah. Indeed a mistery not worth going deeper.

I'll tattoo that command in my brain. I learnt something new today.

Thanks a lot!
