Hi praveenvikram24r, Welcome to LQ. Open a terminal and issue the following commands.

Code:

$sudo ifconfig -a
$sudo route -n
$cat /etc/resolv.conf

You may also want to try pinging anything if you have no connectivity.

Code:

$ping -c4 google.com
$ping -c4 74.125.228.38

Any other data you can provide may help us to diagnose your problem, i.e. is this a wired or wireless network connection, do you lose connectivity at specific times of the day, when you lose connectivity is it on your local area network (lan) or wide area network (Internet).

Good luck. ;-)
