I have a Raspberry 3.0. I am unable to ping yahoo.com, google.com, and a couple of other sites on Raspberry. I am not able to do apt-get update on the Raspberry. Heres the output of the same.

root@raspberrypi:/home/pi# apt-get update

W: Some index files failed to download. They have been ignored, or old ones used instead.

I did add the gateway to my existing connection. I am not able to ping http://mirrordirector.raspbian.org.

I did this further.

root@raspberrypi:/home/pi# nano /etc/apt/sources.list

root@raspberrypi:/home/pi# wget  http://archive.raspberrypi.org/raspbian.public.key -O - | sudo apt-key add -
--2016-05-27 13:03:48--  http://archive.raspberrypi.org/raspbian.public.key
Resolving archive.raspberrypi.org (archive.raspberrypi.org)... failed: Name or service not known.
wget: unable to resolve host address ‘archive.raspberrypi.org’
gpg: no valid OpenPGP data found.

    You're not connected to internet - are you trying to use wireless - recommend using direct Ethernet connection to start – dbmitch Jun 22 '16 at 14:50

    See if ping works. If it does, your problem is you do not have a DNS server. – goldilocks Jun 22 '16 at 15:44

You didn't connect to the internet.
