I have installed 12.04LTS on my Lenovo T440s, but I simply can't get the wireless to work. I have tried writing
and it only displays PCIPCI (sysfs). Somehow I don't think any/all the drivers were installed during installation, because some of the hotkeys (such as screen brightness etc...) don't work either -- but I'm not sure if this is correct. I have tried updating, but to no avail. What can I do here to test further?
