Hi Vagner, thanks for your quick reply! I tried out your proposal and together with power management switched off (iwconfig wlp2s0 power off) the chipset works like a charm!
A big thank you to you and the professor from India! You made my day :) I just keep wondering now whether the disabled power management will increase the battery drain but maybe the firmware does handle those things by itself... So have a nice day and cheers, Tobias On Sat, Feb 13, 2016 at 02:06:32PM +0200, vagner_ wrote: > Hi Tobias, > > I also bought a laptop some weeks ago with an atheros chipset that required > qca9377 - exactly like yours > > Network controller: Qualcomm Atheros Device 0042 (rev 30) - > > and it took me 2 or 3 weeks trying all kinds of solutions, including > compiling a new kernel, kvalo drives and others.
