Errors in make defconfig-ath10k .. Slow wifi with qualcomm Atheros QCA9377
Solution 1:
Official info: "The QCA9377 is a single-die wireless local area network (WLAN) and Bluetooth combination solution to support 1 × 1 802.11a/b/g/n/ac WLAN standards and Bluetooth 5.0 + HS, designed to deliver superior integration of WLAN/Bluetooth and low-energy technology."
One possible cause for slow wifi is interference between bluetooth and wifi. Before trying an old driver, try configuring your system with a current driver. This is a list of actions by increasing difficulty:
-
Disabling bluetooth. You can do this via CLI with
systemctl stop bluetooth, via GUI with Settings -> Bluetooth -> Move the slider at the top right, or perhaps via BIOS configuration. - Getting closer to the router (at least to try).
-
Changing firmware.
This reports that "removing the
/lib/firmware/ath10k/QCA9377/hw1.0/firmware-6.binfile and rebooting helped. The system works with the previousfirmware-5.bin." -
Changing WiFi band. Select a different SSID, or select the band via
nm-connection-editor. See this and this. See this to show the relevance, even if possibly not your case. - Updating to kernel 5.11.
- Changing WiFi channel. See this and this; requires recompiling the driver.
-
Changing WiFi antenna. For some adapters, it is possible to select the antenna to use. I am not sure yours has more than one antenna. You could check with
modinfo ath10k_pci, it will show allparms that can be selected.
Please post the output of the following commands:
$ modinfo ath10k_pci
$ iw dev
$ ifconfig -a
$ inxi -F
$ dmesg | grep ath
As per this recent post, there are not so many options for the driver: irq_mode, reset_mode.
Perhaps now there are a few more.
If alternatives above don't work, you could try
- Using a backport, as you tried. To solve this part, please post more info. In which directory you are compiling? What are the permissions? See this old answer.
