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
:
