Lenovo E220s and no Wifi problem

on

After running ThinkVantage System Update my Wifi was still not working. Checking devices showed that I have “Network Controller” device with no driver for it. Lenovo support page did not help. Actually,  support page does not know that my model (5038-2BG) exists. After a short call with IBS support, they sent me the correct driver. As usual, there is no guarantee that this will work for you. Big thanks goes to the guys and gals at IBS for their nice and blazingly fast support!
