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:[    2.269128] ath10k_pci 0000:01:00.0: pci irq msi oper_irq_mode 2 irq_mode 0 reset_mode 0[    2.546004] ath10k_pci 0000:01:00.0: Direct firmware load for ath10k/pre-cal-pci-0000:01:00.0.bin failed with error -2[    2.546040] ath10k_pci 0000:01:00.0: Direct firmware load for ath10k/cal-pci-0000:01:00.0.bin failed with error -2[    2.556185] ath10k_pci 0000:01:00.0: qca9377 hw1.1 target 0x05020001 chip_id 0x003821ff sub 105b:e0a1[    2.556192] ath10k_pci 0000:01:00.0: kconfig debug 0 debugfs 1 tracing 0 dfs 0 testmode 0[    2.557620] ath10k_pci 0000:01:00.0: firmware ver WLAN.TF.1.0-00267-1 api 5 features ignore-otp crc32 79cea2c7[    2.625627] ath10k_pci 0000:01:00.0: board_file api 2 bmi_id N/A crc32 93da0176[    4.406204] ath10k_pci 0000:01:00.0: htt-ver 3.1 wmi-op 4 htt-op 3 cal otp max-sta 32 raw 0 hwcrypto 1[    4.412611] ath: EEPROM regdomain: 0x69[    4.412613] ath: EEPROM indicates we should expect a direct regpair map[    4.412614] ath: Country alpha2 being used: 00[    4.412615] ath: Regpair used: 0x69lspci -v shows this information about the network controller01:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)    Subsystem: Foxconn International, Inc.

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 iwconfigwlan0     IEEE 802.11  ESSID:MY-WIFI            Mode:Managed  Frequency:2.437 GHz  Access Point: 3C:7A:8A:F7:A2:C8             Bit Rate=1 Mb/s   Tx-Power=20 dBm             Retry short limit:7   RTS thr:off   Fragment thr:off          Power Management:on          Link Quality=50/70  Signal level=-60 dBm            Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0          Tx excessive retries:0  Invalid misc:16   Missed beacon:0lo        no wireless extensions.And iwlist scan | egrep -i 'ssid|cipher' gives me thislo        Interface doesn't support scanning.

I little bit late for a party but I also had to connect to eduroam at some point of time and here is my config that works (for me at least):Description='Eduroam Tartu Student Village'Interface=wlp8s0Connection=wirelessSecurity=wpa-configsectionIP=dhcpWPAConfigSection=(        'ssid=eduroam'        'proto=RSN WPA'        'key_mgmt=WPA-EAP'        'eap=PEAP'        'identity=<mylogin>'        'password=<mypass>'        'phase2=auth=MSCHAPV2 password=<mypassagain>')And also I receive the same errors as you. Though it causes my wireless card to behave weirdly sometimes. After the last update it even fails to reconnect after waking up from a sleep.
