That reply is reporting a DNS failure - its causes could be various. 
Is basic connectivity working, at all, beyond the GW?  Here's how to 
find out.

I suggest, instead, that you try:

ping 8.8.8.8

which is Google's DNS service machine.

Report back if you can ping.  Include reports back when trying from 
(a) the GW device, and
(b) a LAN device
