I have a Lenovo IdeaPad S10-3, it was upgraded from Windows 7 Starter to Windows 10 early august. Working find everything until updating to version 1511 in november, after rebooting with the new version the WiFi appears disconnected, it only shows airplane mode and I can only connect to internet by cable. I have tried changing drivers, disconnecting and reconnecting wireless, even going back to former Windows 10 version, etc. but no way. WiFi appears with a red cross!. Can somebody help me about this? . Why WiFi worked so fine in the former version and why it´s disconnected in the new version?. Thanks in advance.
