How Did I Solve Wifi Problem On Ubuntu 16.04 For Lenovo Z580
All problems started after I update my Ubuntu 16.04 LTS and wifi driver has gone. I spent so many times to solve this problem. Actually there is no problem. There is driver more than one.
After I update Ubuntu I realized, update that I did, installs an other driver of broadcam. That new wifi driver installation caused the wifi problem.
As the result, all you need this command :
That command will remove broadcam installation which had been installed by update.
Lastly...
Reboot your system :
That's it. Now, Everything could be okay. This method solved to my problem. I hope, it will also be useful for you.
