I'm using Arch Linux (4.8.13-1) on an Acer Spin 5 notebook. WIFI is working, but there are some errors in dmesg | grep ath which I don't understand:

lspci -v shows this information about the network controller
01:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)
Subsystem: Foxconn International, Inc. Device e0a1
Flags: bus master, fast devsel, latency 0, IRQ 280
Memory at b1000000 (64-bit, non-prefetchable) [size=2M]
Capabilities: <access denied>
Kernel driver in use: ath10k_pci
Kernel modules: ath10k_pci
I would like to know how to fix this. I think this might solve some issues I'm having with the controller. I somehow cannot correctly connect to my Universitys WIFI. I thought this might have to do mith these errors which appear in dmesg. I tried NetworkManager, connman, wicd, netctl, and with all of them I could only get an IP-address in the network but no connection to the internet. Same with the Universitys eduroam network. I already tried lots of different configurations, but none worked.
This is the output of iwconfig

lo no wireless extensions.
And iwlist scan | egrep -i 'ssid|cipher' gives me this
lo Interface doesn't support scanning.
