    Hi guys,

    I keep having issues waking up from sleep with my T440s. It WILL NOT connect to wifi and the wireless adapter under windows adapter settings disappears. Only thing that fixes this is a reboot. I have removed "allow windows to turn this device off" under wireless settings.

    Driver: 17.12.0.4
    Dated: 28/08/2014
    Software: Lenovo Access Connections

    I do not use windows to connect to WIFI. I have dedicated profiles for each of my wifi networks at home and work.

    This is a serious productivity killer.

    Any help would be appreciated.

    Thanks!

    I don't know about Windows 7, but Windows 8.1 automatically installs 16.5.3.6 for the card when it detects it, and that's worked fine for me (I still have "allow windows to turn this device off" unchecked though).

    I will note that 17.12 also gave me issues like that with my t440s and 7260AC, and I'm running Windows 8.1 without Lenovo wifi utilities. I ultimately uninstalled the card in device manager (telling it to delete the driver), scanned for new devices, and Windows reinstalled it with 16.5.3.6. I didn't even have to restart (although if you uninstall the card, Windows will detect it on reboot just the same).
