I have a notebook with QCA6174 802.11ac Wireless Network Adapter. Initially it doesn't work on ubuntu 16.04.



I've copied this firmware files:



https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174



into /lib/firmware/ath10k.



I've also renamed file /lib/firmware/ath10k/QCA6174/hw3.0/firmware-4.bin_WLAN.RM.2.0-00180-QCARMSWPZ-1 to firmware-4.bin
and /lib/firmware/ath10k/QCA6174/hw2.1/firmware-5.bin_SW_RM.1.1.1-00157-QCARMSWPZ-1 to firmware-5.bin.



Now network-manager see wifi adapter and connects. It works fine but after a while internet stops working.



There are no error messages in journalctl -ru NetworkManager.service in this moment.



And wi-fi works again after sudo service network-manager restart



This is my iwconfig:



wlp2s0 IEEE 802.11 ESSID:"MyWiFi" 
Mode:Managed Frequency:2.412 GHz Access Point: D4:6E:0E:51:3F:AE
Bit Rate=1 Mb/s Tx-Power=20 dBm

enp7s0 no wireless extensions.

lo no wireless extensions.

          Please try disabling power saving in Network Manager. From the terminal:



          sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*
