My WiFi doesn't work. However, a driver is claimed. There is no soft nor hard block.
The laptop I'm dealing with is a Lenovo B570e. On the link below you can see this is a verified laptop for the use of Ubuntu.
I also tried this, which gave me a bunch of errors.
Download this drivers: compat-wireless-3.6.8-1.tar.bz2
Install the drivers:
tar -xf /path/to/compat-wireless-3.6.8-1.tar.bz2
sudo make install
Reboot your computer.
