connecting to Google or Yahoo. These two sites are usually up.

different browsers.
3> Reboot
your router and modem. ( Cycle power on both )
4> Open a
command prompt and type in the following:
ping google.com
ping
87.248.113.14
(Yahoo)
ping 74.125.77.99
(Google)
If pinging google.com succeeded but the browser failed you have a
corrupted or infected browser.
If pinging google.com failed but pinging the ip address succeeded
then you have a DNS issue.

plugging in these OPEN DNS numbers
