I checked to install drivers. In my case it says that no need to install anything. The driver I have is [14e4:4727] (rev 01). — Geetartha Goswami, Oct 20 '14 at 08:09
Did you check out the DNS answer below? Do you remember ever installing the drivers? — Seth, Oct 21 '14 at 01:58

You are most likely having a DNS problem. You can check if you have intenet connectivity by pinging a host that may certainaly be connected. Try pinging Google's DNS server:

$ ping -c10 8.8.8.8

If you get a positive response try add an entry to the top of your /etc/resolv.conf file:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

nameserver 8.8.8.8
search [your preferred domain suffix such as mydomain.com]

The search option isn't a requirement, but can be a convenience facility to use single word host names for your local machines.

If your internet browsing starts working after the resolv.conf change, you can make this automatic by adding a head to your resolvconf configuration files:
/etc/resolvconf/resolv.conf.d/head:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN


nameserver 8.8.8.8
search [mydomain.com]
