Back Story : I have upgrade to 18.04 from 16.04, but operation didn't completed successfully, my dpkg was broken then somehow I restored it and I'm able to logged in after upgrade but even though I have plugged Ethernet cable, I'm not able to see anything connection icon in upper right corner so I have checked
ifconfig command then I'm able to see my network adapter.
After that I have manually configured my IP address, default gatewat etc and somehow my network started working but connection is not stable..
Summary of my problems
- Not able to see Network option to do changes using UI
- Network connection is not at all stable
