only one ping from router

[Josh Stratton]

The internet on my desktop suddenly stopped working while watching a video.
 I don't think anything has changed recently as far as configuration goes.
 It seems like the eth0 interface is getting an IP address from my router,
but I can only ping myself.  dns names don't resolve like if I ping
yahoo.com.  If I ping the router at 192.168.0.1, I seem to only get one
response back before it hangs and times out.  I've been trying to debug
this myself, but I'm unfamiliar with what files are used for what now.

Is there something I can do to fix networking?  Other computers attached to
the router don't seem to be having any issues.
