Poor link speeds and signal strength on Qualcomm QCA 9377

Poor link speeds and signal strength on Qualcomm QCA 9377

[Arvind Bakshi]

Sir/Mam

Getting 1 mbps link speed and average signal strength, even on
standing next to router on every linux distro whereas windows 10 gives
150 mbps link speeds and excellent signal strength even standing quite
far off from router. Tested on Fedora 30/31 and ubuntu 18.04/20.04.
Turning off wireless power management : sudo iwconfig wlan0 power off
doesn't make a difference.
Turning off all power saving options using TLP also doesn't make a difference.
Software (OS, Firmware version, kernel, driver, etc)
Tested on Fedora 30/31 and ubuntu 18.04 LTS
Wifi card: Qualcomm QCA 9377
Device: Dell Vostro 3468 (shipped with ubuntu 16.04)

Hardware (NIC chipset, platform, etc)
Qualcomm QCA 9377



Please provide driver fix for this wireless card.

Thanks & Regards

Arvind Bakshi

I have exact same card, works fine on recently installed and updated
ubuntu 19.10 with kernel 5.3.0

How did you end up on 5.4.0 with ubuntu 18.04? From update manager?

My first guess is a problem with calibration data, for example using
wrong board data file (which are device specific). Unfortunately I don't
know what would be the correct board data file for your device, ath10k
is supposed to choose it automatically but we don't always have all
board data files available.

There's nothing wrong with calibration data. Board and firmware
checksums are the same as on my system. Probably kernel problem
again..
