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.
