hi, <div class="gmail_quote"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Wait a second. If you have two interfaces, typically only one of these interfaces is connected to the network which eventually is connected to Internet. That's the network where your default gateway machine is. Why are you trying to ping default gateway FROM ANOTHER network?!</blockquote><div> No both the interfaces are on the same eval board.........Imagine a laptop that has ethernet and wifi card connected to a router,that acts as an access point as well as a default gateway for ethernet.So a ethernet RJ45 cable connects the ethernet of the eval board to router and the wifi card gets connected to the access point(router) since the router is a wireless router. So what i am trying to do is ,i have both ethernet and wifi card on the eval board......both gets connected to the verizon router which acts as an access point as well as default gateway for ethernet. Now i want to check whether both my ethernet and wifi card were able to reach a web server...... so first time i ping google using ethernet.............. Then i change the interface to wifi using $ping -I eth1  <a href="http://64.233.167.99/" target="_blank">64.233.167.99</a> where it hangs............... My ethernet is eth0....... My wifi is eth1.......... Regards, Ram  </div></div>
