Just a standard wifi-not-working question. A fresh Ubuntu 16.04 and is up to date. Laptop model number in title.

I used the "Wireless info script" in the accepted answer here and there's the result:

Run in terminal

sudo tee /etc/modprobe.d/blacklist-acer-wmi.conf <<< "blacklist acer_wmi"

and reboot.

This solution is helpful for laptop models when the rfkill shows acer-wireless and it is blocked.

  • "you can accept an answer in 7 minutes" thank youuu :'D ...this command appends the line blacklist acer_wmi into the file /etc/modprobe.d/blacklist-acer-wmi.conf right? – 842Mono Sep 30 '16 at 14:12
  • Correct. You can do it manually, if you like it ;-) – Pilot6 Sep 30 '16 at 14:12
  • hehe yeah. how did this line fix the problem? plz tell me (briefly) if you have some time to spare :D – 842Mono Sep 30 '16 at 14:15
  • The acer_wmi module blocks your wireless. A better way is to add a quirk specific to your laptop model to avoid it. But in most cases blacklisting acer_wmi is good enough. This lines prevents loading of acer_wmi. – Pilot6 Sep 30 '16 at 14:17
  • I see. okay thx again :) – 842Mono Sep 30 '16 at 14:18
  • @Pilot6 It will be great if you could expand the answer with what you said in the footnote. Since this is a model specific fix, we don't want others with wifi not working for other reasons to try this. – user68186 Sep 30 '16 at 14:43

    I added a note to the question. But there is no harm if someone uses this solution on a wrong laptop. It should not brake anything ;-) – Pilot6 Sep 30 '16 at 21:41
