I don't know how to ping ? But i have resolved the the issue of connectivity by changing my modem! I am now using different modem however i am encountering a different problem i am not able to update software using update manager it says check your internet connection even though i have a working internet connection. Any idea what to do to resolve it. Thank you. I appreciate your time and help.

It's the same in all OSes. Press CTRL+ALT+T and run:

ping -c 4 8.8.8.8

Does it ping

Ok then run:

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

And it will apply the DNS, basically the issue is that the DNS you currently have sucks but (as you can see) networking is not an issue as 8.8.8.8 pings ok. Using the IP bypasses the need for DNS.

You should now be able to run:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

8.8.8.8 is Google's public DNS and very easy to remember, use that to get the upated then reboot and it may make the OS use the DHCP DNS better, or you can apply Google's public DNS permanently but lets see if adding the DNS manually and getting updates fixes the whole issue
