Atheros QCA9377 wifi signal reception and speed problem

Hi,
I just shifted from windows to linux.
I have tried Ubuntu and now I am running latest version "19.0.2 kiyara" with KDE Plasma desktop.
I am having problems with my wifi. I was suffering from this problem on Ubuntu also but it was just fine when i was on windows.
Problem is that my wifi adapter shows very poor network signal strengths, i mean for every network it shows. even i tried placing my machine right next to the router and it show the network signal strength like 45%~50% as if it is dividing the actual strength by 2, and then showing it to me.
Its not the only thing, I has very poor download/upload speeds also.

I tried connecting external wifi adpter(tplink TL-WN722N v1) and that thing shows the accurate signal strengths,proper speeds and works just fine.

I checked the hardware drivers in "System settings" app and i found that there were some drivers installed for TP-link adapter but i think there are no drivers install for my internal wifi.

here is the screenshot:

I also tried installing the drivers and while searching i couldnt find any defined packages for my wifi card like windows but if found these https://github.com/ajaybhatia/Qualcomm-Atheros-QCA9377-Wifi-Linux and https://github.com/kvalo/ath10k-firmware i tried both of them but no success.
so i don't have any idea how to get this problem solved, and i really don't want to go back to windows.

I hope i could get this thing solved by help of you guys.

Thanks in advance!

very interesting. i have the exact wifi card in my laptop as you and i have no problems at all.

what kernel are you using?

please send me what inxi -Fxxxxx says in your terminal

it is "5.4.23-1-MANJARO x86_64"

please do a full system update with your ethernet cable connect to your router. do a reboot.

looks like those drivers are outdated. it is better for you to use the certified kernel drivers. either linux54 or linux55. make sure you have linux-firmware package installed

having this usb connection could be a problem.

to upgrade. make sure you sync from updated mirrors from your country.

then run sudo pacman -Syyu and accept defaults

device 4 even liike suspicious. you man need to blacklist those other card except for device 1, which is your QCA9377

okay, I tried the full system upgrade and I also installed "linux-firmware", but still no good.
still same signal strengths and speeds.

I think the "Device-4" is the bluetooth as the description says "USB driver:btusb"
and "Device-2" is the ethernet device.

very strange, maybe you will need to talk to philm the manjaro boss as your hardware id might not be listed

how am I supposed to reach him ?
and btw this is not happening here on manjaro only, i had this problem on ubuntu too

very strange. silly question coming up...is your QCA9377 turned on in your BIOS?

i think it would not be working at all if it was not enabled in BIOS,
though i nor have checked if it is or not, neither i know how to check it.

you can check the signal strengt with 'nmcli dev wifi'

can you give me out of lsmod please

@olli i tried it, and it shows only 22% while i am in next room to the router

here u go

okay you're using the atheros 9 drivers

As of Linux 3.15.1, some users have been experiencing a decrease in bandwidth. In some cases this can fixed by editing /etc/modprobe.d/ath9k.conf and adding the line:

options ath9k nohwcrypt=1

https://wiki.archlinux.org/index.php/Network_configuration/Wireless#Power_saving_2

that's what i thought too, but looking all the way through, found that ath10k are loaded as well. would this cause interference?

he is using the QCA9377 chipset as well, so that would use the ath10k driver. i have the same chipset

so keep going with him, because you can check it better while your wifi is similar.

can you please disconnect from all of your usb wifi cards please. then connect only with QCA9377 wireless card.

i forgot to mention that after you have disconnected your usb wireless cards. it is best to reboot. when you log back in, don't use any usb dongles

nope. i disconnented external wifi card, rebooted and it shows the same stats
but i think lsmod output has changed a bit, take a look here:

give this a try
' sudo echo "options ath9k nohwcrypt=1" >/etc/modprobe.d/ath9k.conf ' and reboot

I already have done that, when u last suggested it. But, no luck, its still the same.

Have you managed to resolve the issue? I have a similar problem with the same wifi adapter.
