    ATHEROS AR9285 WLAN not working with LENOVO B570 (with ubuntu 12.04)

    Hi there,

    The HW switch for the wireless card in my Lenovo B570 laptop keeps switching off for unknown reasons. Until now I was able to fix the issue by blacklisting acer_wmi module but it no longer helps.

    The laptop does not have a physical switch for Wireless, just the Fn+F5 combination. That gets recognized by Ubuntu but has only effect on the software switch.

    I have also tried the power button suggestion (remove battery and keep power button pressed for more than 30s) but no luck.

    Code:
    lspci -nn|grep Ather
