What I expected to happen
===========================
WiFi card (QCA6174 802.11ac Wireless Network Adapter) works properly, as
it did with kernel series 4.10.
What happened instead
=======================
Since upgrade to 4.13 series, WiFi card loses connection to access point
(can't even ping access point) while Ubuntu still believes it's properly
connected. It needs to be disconnected and reconnected to access point
to regain a real connection.
Solution
==========
>From https://askubuntu.com/a/978143/616451:
The solution is simple: install updated firmware from firmware
repository provided by Qualcomm.
Detailed steps:
1. Download https://github.com/kvalo/ath10k-
firmware/blob/master/QCA6174/hw3.0/board-2.bin and overwrite
/lib/firmware/ath10k/QCA6174/hw3.0/board-2.bin with the downloaded file.
2. Download https://github.com/kvalo/ath10k-
firmware/blob/master/QCA6174/hw3.0/4.4.1/firmware-6.bin_WLAN.RM.4.4.1-00065-QCARMSWP-1
and overwrite /lib/firmware/ath10k/QCA6174/hw3.0/firmware-6.bin.
3. Restart
