Suddenly... No wifi!

[Thomas Tanghus]

Hi,

I was just sitting here, doing my stuff, when suddenly I had no network. I checked 
my other devices, and they could use the wifi just fine. The network widget (I'm 
using Plasma) was disabled and wifi couldn't be enabled again. Maybe I had hid 
some wifi kill-switch on the keyboard? It's a "new" laptop (new to me), so after
finding the manual and the kill-switch (Fn-F5) I tried it out while tailing journalctl:

It's kinda hard to see if it's turning it on or off, but I can see it in the network widget. See attachments.

BUT - when I click to enable wifi again, it changes to the wifi off and prints to the journal:

Any idea what wen't on here? Did the wifi chip just die? That takes mobility out of the equation :(
