I had wifi connection on Ubuntu 16.04 with no problems, but now it is off and wlan0 status is "disconnected". What command or shortcut should I use to get wifi going again?

Could you check out this question, and the output to yours. Use http://pastebin.com if it is too long. – mikewhatever Nov 11 '17 at 19:39

To turn wlan0 on, in a terminal type:
sudo ifconfig wlan0 up

Thanks Doudou, should I reboot, because wlan0 is still disconnected ? – mario jardim Nov 11 '17 at 18:04

No normally not. Can you provide with the last apt log (the one from today) doing
gedit /var/log/apt/history.log? – Doudou Nov 11 '17 at 18:08 -
Sorry, but this command "gedit /var/log/apt/history.log" returns a blank page. – mario jardim Nov 11 '17 at 18:15

mhmh that's weird. Anyway stupid question but, do you have by any chance on your keyboard a wifi key? On mine F12 is actually assigned to switch on/off the wlan card – Doudou Nov 11 '17 at 18:19

I do not know about that key, I have a recent HP Pavillion with a 17" screen, but I will try the f12 right now – mario jardim Nov 11 '17 at 18:23

The f12 key did turn on and off the check mark besides "activate wifi network". Now I will check if wlan0 is still off. Back in a sec. – mario jardim Nov 11 '17 at 18:26

Wlan0 sill disconnected. I have to leave for a while, but I will be back shortly. We will keep trying to solve this one. – mario jardim Nov 11 '17 at 18:29

Hi, is anyone able to help with my wlan0 being disconnected? Suggestions made by Doudou could have been helpful but I am still with ''wlan0 disconnected'' problem. Thanks – mario jardim Nov 16 '17 at 12:49
