Qualcomm Atheros QCA9377 disconnects periodically
By Daniel Johnston
I am currently using Ubuntu 18.04, but my wireless connection stops working from time to time. Sometimes it works fine the whole day. However, other days it just keeps disconnecting, so I have to manually reconnect each time.
At times it just stops working completely and the wifi card does not even get recognized anymore. My only way to get it back working then, is to reboot.
$ lspci -nnk | grep 0280 -A3

On elementary OS 6, based on Ubuntu 20.04.2 with kernel version 5.11.0-25-generic, the following worked for me:
sudo mv /lib/firmware/ath10k/QCA9377/hw1.0/firmware-6.bin /lib/firmware/ath10k/QCA9377/hw1.0/firmware-6.bin.oldBased on this answer. If it does not work for you, you can revert the change by renaming firmware-6.bin.old back to firmware-6.bin.
I was able to solve the problem of instability by entering the router settings and changing the Bandwidth from 20/40 to 20, considering that my router only supports 2.4GHz, if your router is 5ghz I think it should be better to set to 40 instead of 20.
I'm still looking for a solution to the problem of not recognizing the wifi card, but for now I can only solve by restarting too..
good luck!
