[SOLVED] My network disconnects several times a day. After a reboot it usual happens less often for a period. It can often occur after the laptop was in sleep mode. Usually I can just turn the network off and on again and it usually works again.
I've tried the fixes I could find on the forum including replacing the firmware folder for Qualcomm Atheros QCA6174 802.11a wireless network adapter.

Your computer is reasonably new. Why not move up, via a clean install, to Mint 21.3, with the latest kernel and see what happens. Things are intended to improve.
I've upgraded to linux mint 21.3 and the problem still persists.
Now the kernel I have is 5.15.0-101-generic
Any ideas how I could even find the problem? I've been trying to search the logs with command: journalctl -u NetworkManager -n 100
or searching in /var/log/syslog but I can't find the cause. Then after a while I use command: sudo modprobe -r ath10k_pci && sudo modprobe ath10k_pci and it works again thereafter.
Try an even newer driver:
Update Manager - panel: View - Linux kernels
Install the latest kernel of the 6.5 series. Then reboot and test.
If that doesn't help: sleep mode, especially suspend-to-disk, is sometimes problematic. suspend-to-ram does a little better. It might help if you make sure that your BIOS is of the latest version.

I have update the BIOS and the kernel to the 6.5 series.
The problem persists. Power management is off and in file /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf wifi.powersave =2.
I tried to change suspend-to-disk to suspend-to-ram but I don't really know how to do this.
I tried doing is with
sudo nano /etc/systemd/sleep.conf
and changing the line
#SuspendMode =
to
SuspendMode = ram
But after this I no longer have suspend mode option in power management so I would have to shut down the laptop instead of suspending.
Is there a better way to suspend to ram?
I'm afraid this is a misunderstanding. My suspend comment was simply a sideline, meant to indicate that using either sleep mode (both ram and disk) might cause problems like this on some hardware combinations (yours probably included). Leaving only full shutdown as a good option.
Whatever you try next: undo that change in /etc/systemd/sleep.conf.
One thing you might still try, is this:
1. Make a Timeshift snapshot for easy reversal;
2. In the terminal:
