Title:
QCA9377 WIFI does not work
Status in linux package in Ubuntu:
Incomplete
Bug description:
My laptop, acer E5-575-53EJ, sometimes boots without wifi connection being
detected.
Restarting the network-manager sometimes fixes the problem.
dmesg | grep ath shows the kernel log.
The system finishes booting at 12.x seconds with no wifi connections.
Network-manager is restarted around 3x seconds and connection is established
around 78.x seconds.
Then firmware crashed at 624 seconds, followed by a successful recovery.
At 915.x seconds a suspend is attempted, followed by a restart of
network-manager scheduled by systemd. Connect was lost.
Launching Wicd network manager recovers the connection, but the
network-manager shows nothing.
Ubuntu: 17.04,
kernel: 4.10.0-19-generic
Firmware:
I tired the qca firmware at
https://github.com/kvalo/ath10k-firmware/tree/master/QCA9377/hw1.0 .
all three files have the same md5 as the one installed by default.

repeated PCIE errors. I upgraded bios to 1.25 and PCIE errors are gone, however
wifi does not improve.
