  • I see I'm hard blocked but this machine has no WIFI switch and it's enabled in BIOS. – lai Jan 31 '17 at 23:46

First, check if this fix will work for you. Terminal:

sudo modprobe -r ideapad_laptop

If that fixes WIFI, which it did for me. Make it permanent. Terminal:

sudo nano /etc/modprobe.d/blacklist.conf

At the bottom of the file, add the lines:

# Fix for WIFI hard block
blacklist ideapad_laptop

  • Welcom to Ask Ubuntu. It's always ok to answer your own question and sometimes one person finds an answer at more or less the same time that someone else does, so there's no problem there either. But rather than using the world 'solved' like a forum, you want to accept your answer. It may take a few hours before the system lets you do that. – chaskes Feb 01 '17 at 00:15

I would run this in terminal

echo "blacklist ideapad_laptop" | sudo tee /etc/modprobe.d/ideapad.conf

Reboot and see if wifi works

Then if wifi works post results for sudo dmidecode | grep -i version in case a kernel developer sees this
