Although all this seems sensible to me,
I am a bit surprised none of you gurus has suggested using "ping".
I would start by pinging my ISP, if possible using the IP address.
To me, the first question would be, "Are my packets leaving the house?"
If I determined that they were, I would think to myself,
"So it's a pretty simple issue then, probably something to do with DNS,
or maybe DHCP."
If I found the packets were not leaving my house,
I would be much less sanguine.
