Wifi disappears after boot

I was using Zorin OS 16 and my wifi started disconnecting (it did not happen for months after I install Zorin 16) after like 5 minutes later after boot and I was not able to see any wifi in Networks section after the disconnect. I couldn't find a solution so I switched to Kubuntu 22.04. Now I still have the same issue. Weird thing is, this does not happen at work internet, it happens only on my home internet.

I have another laptop with different wifi adapter and there are no issues with it.

What I tried so far:

• Reset modem
• Install this (after installing this it was okay whole day but after then I went to job and came back and it occured again)
• re-install NetworkManager

Here is my wifi adapter:

I changed wifi.powersave from 3 to 2 in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and no problems so far. I'll update here if it happens again.

I had similar problems that solved disabling (with a workaround) my network card power-saving... long story - short solution...

try to run the following script as cron job (root user), and let me know if this solve your issue.

PS: I think it's a driver issue, but in my case this workaround solve the problem. Let me updated, please.

SHELL=/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=""

* * * * * root for i in {1..12}; do (echo 'on' > /sys/class/net/"$(ls /sys/class/net/ | grep -v '^lo')"/power/control) 2>/dev/null; sleep 5; done;

PPS: The "$(ls /sys/class/net/ | grep -v '^lo')" block is used to find the first Ethernet Device Card.
