No network at all.

Good Folks.

Looks like I am not on network at all.

Your netmask is wrong. 32 is a single IP address, so 192.168.1.3 and 192.168.122.1 are on two different subnets.

[bluemind2005]

Correct Netmask .32 was the issue:
Solution was to change PREFIX=32 to PREFIX=24 and I also added line NETMASK=255.255.255.0

Restarted network and then all good.
