Later, I created a cronjob to check ping results and perform the same command on ping failure - as a temporary workaround. Once connection is lost, I used "nmcli c up wifi_ssid" or "nmcli c up enp4s0" to manually bring it backup. NetworkManager status (systemctl -l status NetworkManager) shows active and running.

When connections are lost, ping fails to other network/internet IPs/domains. I didn't try driver re-installs or testing with difference hardware (which I don't have).
