Hi,

I'm having troubles with ar9285 chipset on lenovo g5757 and have no idea what to do.
* wireless card is enabled in BIOS
* no luck with lenovo energy management [http://208.74.204.134/t5/Linux-Discu...ux/td-p/880185] (I couldn't find the magic enable wireless switch and considering rfkill list all output shows everything is unblocked, I didn't pursue wiping BIOS memory option)
* most related problems are caused by acer_wmi, I do not have it
* nohwcrypt=1 makes no difference.

lspci -nn | grep Wireless
