Cronjob not working and WiFi disconnects automatically

[daddyodevil]

My main problem is that my wifi gets disconnected automatically showing a '?'(question mark) on the icon in the panel. I can switch it off and back on to make it function normally again.

My chipset -

lspci | grep -i wireless
02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)

Things I have tried -

Setting the following to 1, 2, 0 -

/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Replacing my original files by the ones here -

https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174

And some things here and there that I don't remember.

The solution that finally works for me is running the following script every time after boot -

#!/usr/bin/env bash
DISCONECT_COMMAND="nmcli d disconnect wlp2s0"
RECONECT_COMMAND="nmcli d connect wlp2s0"
SLEEP_INTERVAL=10
    
function is_down {
    ! ping -q -c 1 -W 1 "$1" &>/dev/null
}
    
  
while true; do
    # check multiple sites, if one is up then there is internet
    if  is_down "google.com" && is_down "1.1.1.1" &&  is_down "facebook.com" && is_down "8.8.8.8" ; then 
        eval "$DISCONECT_COMMAND"
    date
        eval "$RECONECT_COMMAND"
    fi
    sleep "$SLEEP_INTERVAL";
    done

But I am having to this manually as writing a cronjob for it didn't help.

My crontab file -

...
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
# 
# For more information see the manual pages of crontab(5) and cron(8)
# 
# m h  dom mon dow   command
    
@reboot sleep 600 && /home/puku/reconnect_wifi.sh

My crontab logs (not giving the whole thing)-

I am using Ubuntu 20.04 with 5.4.0-29-generic kernel, but this problem was there is in 18.04 as well and Ubuntu derivatives.
Any help is really appreciated.
