W-lan not found on Lenovo

Question

I work with a Lenovo B580 and Ubuntu 16.04. My device doesn't find W-Lan anymore (used to up until 2 weeks ago). I use this wlan device and drivers. Any suggestions for help?

What is the exact response from the terminal command: sudo modprobe wl Required key, maybe?? — chili555, Aug 23 '16 at 23:02
modprobe: ERROR: could not insert 'wl': Required key not available
What now? — Tralfie, Aug 24 '16 at 12:03

Did you try checking the blacklist.conf file in the folder /etc/modprobe.d ?? Sometimes my wifi seems useless on various computers/ubuntu versions. Usually putting a # in front of the next ones solves the problem for me.

blacklist eth1394 blacklist bcm43xx

( Yes, you need to ben root to do this of course :-)
