So, today I bought this machine (Croatian site but you should be able to analyze the specs). There were no CD's in the box. Fortunately, the Windows Update service (I installed Win 7 x64) was able to find drivers for all the components...
... except one - the WLAN controller.
So, this is my Device manager:
and the Network connections:
As you can see, the WLAN controller is labeled "Network controller" and there is a yellow triangle (meaning "no drivers available").
You can also see that I have a Bluetooth connection and a LAN connection, but a WLAN connection does not exist on that notebook.
Now, the first thing I did was go to the lenovo drivers page. Scroll down to the "Networking - Wireless" section and you will see that there are drivers available for Intel-branded WLAN controllers. Those drivers won't help me since my machine is based on an AMD solution (I actually did install them and they didn't solve the issue, so I uninstalled them).
So, where can I find the drivers for my WLAN controller?
Update: I found the driver here.
