Net adapters both get up, but no internet connection made

I think I screwed it up when tried to install Network Manager over networkd running service. I have Ubuntu server installed on a brand new Raspberry PI 4 with only 1GB of ram, hence 'server'...

Much of the answers seen around are for Network Manager which is installed on desktops.

Uninstalling Network Manager didn't work. I think I did it. Hard to be sure.

Both interfaces, eth0 and wlan0 show same behavior. Up with IP address and all, but no internet connection .

netplan status shows both IP address and default route assigned.

Ping success over local phone or router.

---> PING SUCCESS TO UBUNTU.COM. OR GGL.<---

Any thoughts?
