eMMC can't be recognize after 6 months idle

[dukla2000]

Try to setup a static IP
# ip link set up dev eth0
# ip addr add 192.168.0.20/24 dev eth0  (depending on your network)

and then try to ping an another ip/computer on your network
is this working ?

To try simplify I reloaded a minimal image as it uses systemd-networkd (and not NetworkManager as per the xfce & kde images).
It works somewhat better, the log is below. 192.168.1.1 is my router. What is horrific is the packet loss. the second bit is from ip address.

Code:

Just rebooting into my Ubuntu setup I get

(ip route under Manjaro gives null response)

I truly appreciate your patience trying to help this dumbo, thank you
