Title:
Wifi drops, particularly under load
Status in linux-firmware package in Ubuntu:

Bug description:
On Ubuntu 18.04.3 LTS with Qualcomm Atheros QCA6174 wireless card, internet
drops out, particularly when downloading at speeds ~1MB/s say via P2P torrent.
The wifi connection (at least reported by wicd) remains active, but I cannot
ping the router or access the internet. No error message is logged in
journalctl after the internet drops. Details on my card, firmware and dmesg
given below I'm not the only one with this issue:
