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. None of them worked.
Finally, I found a drive that a professor from India, I think, wrote
then I installed a new kernel 4.0 and the drive and since then it has
been working marvelously.
I even wrote to him to say thanks and got a good reply.
I run Siduction distro with their very updated kernel.
Try this:
Remove your drive and install this one. It is very easy. Just run the
script. Then tell us if that worked for you.
Cheers and good luck...

Hello,
I bought a new laptop from ASUS, Product Name E205SA and installed Arch Linux.
Unfortunately, the included WLAN chipset from Qualcomm (QCA 9377) doesn't seem
to work well with Linux. Beside of being recognized, the driver/device
functions normally for the first minutes after boot, but then the transfer rate
is suddenly lowering from around 700 kbs to 200 kbs and less, making Internet
unusable. After a while, it's recovering a bit but it seems to be random (like
it's trying to sleep/power save mode?). This behavior occures for my home
network as well as at my university's network. As wifi access wasn't a issue
with the Windows 10 OEM installation, I guess that this might a
driver/firmware/configuration problem.
