I installed Lubuntu 16.04 on my Lenovo 3000 N200 laptop, but the "Wifi Networks" is greyed out. In the process of installing OS Wifi hasn't been recognized. Then I decided to reinstall Lubuntu but now with Ethernet cable plugged in. Installation was longer because of simultaneous updates but never the less, Wifi is not working (Ethernet does).
"sudo apt install b43-fwcutter firmware-b43-installer" was mentioned on other forums as well but it didn't resolve my problem.
Previos OS on this laptop was Lubuntu 15.10 and the Wifi was working properly.
PS. I also tried to add my home Wifi manually (entering SSID, Mode, Device and other settings)
