If I want to know if I have an internet connection I look for a default
route in the output of "netstat -an", thus:
netstat -rn | egrep '\''^(default|0\.0\.0\.0) +[1-9]'\'' >/dev/null
No default route - no general purpose internet connection.
A default route but no connectivity? Then something else is wrong that
needs fixing anyway.

We _like_ the starter! Wouldn't have it any other way. If it doesn't grind,
take it back to the dealer and make them fix it!
