Qualcomm Atheros QCA9377 wireless not working on lenovo with Ubuntu 18.04.5 LTS

Question

I did ran the commands in this and this posts, but got the following errors which chili555 mentioned but still my signal keeps being weak.

Tried changing config_enabled to x2apic_enabled with no luck.

EDIT: After following chili555's answer i ran the -uname -r command and it returned this

4.15.0-118-generic

So I downloaded v4.14-rc2/ and it gave this error:

/home/yanes/backports-4.14-rc2-1/drivers/net/wireless/ath/ath10k/htt_rx.c: In function ‘ath10k_htt_rx_alloc’: /home/yanes/backports-4.14-rc2-1/drivers/net/wireless/ath/ath10k/htt_rx.c:510:2: error: implicit declaration of function ‘setup_timer’; did you mean ‘sk_stop_timer’?

EDIT 2: My laptop freezes unless I turn the wi-fi off, tried installing older version instead of newer (v4.1.1) by disabling wi-fi but It returns that I have no permission? Here's the output.

make2: execvp: ./lxdialog/check-lxdialog.sh: Permission denied make2: execvp: ./lxdialog/check-lxdialog.sh: Permission denied make2: 'conf' is up to date. make1: execvp: ./kconf/conf: Permission denied Makefile.real:41: recipe for target 'defconfig-ath10k' failed make1: *** [defconfig-ath10k] Error 127 Makefile:40: recipe for target 'defconfig-ath10k' failed make: *** [defconfig-ath10k] Error 2

A backport file from 2015 is unlikely to successfully compile in more modern kernel versions. Please note the answer at the link you gave that says, in part:

Before executing the wget command check for you linux kernel version.
$ uname -r 
Then go to https://mirrors.edge.kernel.org/pub/linux/kernel/projects/backports/stable/ and check for the closest kernel version available there and then download the backports tar file using the following command.

For example, if uname -r returns 5.4.0-48-generic, then select the backport version that closely matches. In this case select https://mirrors.edge.kernel.org/pub/linux/kernel/projects/backports/stable/v5.4.56/backports-5.4.56-1.tar.gz

It compiles without error on my 5.4.0-48 machine.

Thank you for your answer, I updated my post as I'm still facing errors. – Giannhs Ker Oct 10 '20 at 20:31
Rather than a release candidate (rc2), please try 4.19.112. Does it still fail? – chili555 Oct 11 '20 at 00:06
Now wifi doesn't work at all. what's more screen freezes at startup – Giannhs Ker Oct 11 '20 at 09:47
I doubt that the freeze is related to backports as ‘make’ never succeeded and you never were able to continue to ‘sudo make install’. – chili555 Oct 11 '20 at 11:50
I didn't do anything else though. It has to be that. – Giannhs Ker Oct 11 '20 at 11:55
Could you help me fix this? – Giannhs Ker Oct 11 '20 at 12:27
Can you enter Recovery Mode at the GRUB menu? Does ‘modinfo ath10k_pci’ tell us what version is installed? Backport? – chili555 Oct 11 '20 at 12:55
If the filename is /lib/modules/xxx-generic/kernel/drivers/net/wireless/ath/ath10k/ath10k_pci.ko where xxx is your kernel version, then that is the default and no backport is installed. – chili555 Oct 11 '20 at 13:27
Let us continue this discussion in chat. – Giannhs Ker Oct 11 '20 at 13:35

First Method:

sudo apt update && sudo apt upgrade
sudo apt install --reinstall linux-firmware

2nd Method

(this method solved my issue)

sudo apt remove broadcom-sta-dkms bcmwl-kernel-source 
sudo apt install firmware-b43-installer

3rd Method:

sudo apt update && sudo apt upgrade
sudo apt install fwupd
sudo fwupdmgr refresh && sudo fwupdmgr update
sudo reboot

4th Method :

After few days of testing, it looks like a firmware problem to me. I've tested all the ones available at https://github.com/kvalo/ath10k-firmware/tree/master/QCA9377/hw1.0 and I experienced the very same issue with all the three API6 files (i.e. firmware-6.bin_*).

The latest (in terms of release date) API5 file firmware-5.bin_WLAN.TF.1.0-00023-QCATFSWPZ-1 seemed to work much better but I still experienced the issue after few solid hours.

Eventually, the file firmware-5.bin_CNSS.TF.1.0-00267-QCATFSWPZ-1 seems to be the most stable on my Lenovo Ideapad 320 using:

Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)

So try renaming the existing firmware-5.bin and firmware-6.bin files under /lib/firmware/ath10k/QCA9377/hw1.0/ and use the firmware version I've mentioned. In other words...

 cd /lib/firmware/ath10k/QCA9377/hw1.0/

sudo mv firmware-5.bin firmware-5.bin.orig

sudo mv firmware-6.bin firmware-6.bin.orig

 sudo wget "https://github.com/kvalo/ath10k-firmware/blob/master/QCA9377/hw1.0/CNSS.TF.1.0/firmware-5.bin_CNSS.TF.1.0-00267-QCATFSWPZ-1?raw=true" -O firmware-5.bin

Now load the new firmware and double-check

 sudo modprobe -r ath10k_pci

 sudo modprobe ath10k_pci

 sudo dmesg | grep ath10k

output:

ath10k_pci 0000:01:00.0: firmware: direct-loading firmware ath10k/QCA9377/hw1.0/firmware-5.bin
ath10k_pci 0000:01:00.0: qca9377 hw1.1 target 0x05020001 chip_id 0x003821ff sub 17aa:0901

ath10k_pci 0000:01:00.0: firmware: direct-loading firmware ath10k/QCA9377/hw1.0/board-2.bin
ath10k_pci 0000:01:00.0: board_file api 2 bmi_id N/A crc32 8aedfa4a
ath10k_pci 0000:01:00.0: unsupported HTC service id: 1536
ath10k_pci 0000:01:00.0: htt-ver 3.1 wmi-op 4 htt-op 3 cal otp max-sta 32 raw 0 hwcrypto 1

Make sure the version id just next to firmware ver matches.

I hope this trick will solve that annoying issue for you too ;)

Chilli555 already solved the problem I had. Thank you for your answer, I will use it if need be. — Giannhs Ker, May 26 '23 at 08:38
