Wi-Fi connection lost and reestablished every 3 minutes after upgrade from Lubuntu 22.10 to 23.10

In Lubuntu 22.10 (Kinetic) Wi-Fi connection on my laptop was stable. A couple of days ago I upgraded Lubuntu (installed it afresh) to 23.10 (Mantic Minotaur). Now the connection is lost every couple of minutes and reestablished again in 3-20 seconds automatically. The same issue with two different internet providers (two different routers).

Network manager version as told by command "apt-cache policy network-manager" is 1.44.2-1ubuntu1.2.

My laptop model is Digma CITI E401.

Hello, thanks for your bug report.

Can you collect and attach the Network Manager's systemd journal?

You can get it with "journalctl -u NetworkManager > network-manager.log"

It will help us to identify the problem.

Thank you!

In Lubuntu 22.10 there was another issue with Wi-Fi connection: if it had not been established at boot, there was no way to turn it on, you had to reboot the laptop. I don't know if it was a bug of Lubuntu or a defect of the laptop.

Yes. See the attachment.

Now over an hour after turning my laptop on network interruptions have ceased. Seems like the cause of the problem is in my laptop itself.
