Probably you want to try to connect to something. You can't really say
a connection is up or not... they might have a good connection to
their LAN, but that LAN doesn't have access to the internet. Or even
the ISP has troubles (or the user lives in a country that censors
websites) and not all of the internet is reachable at the moment...

If you want to connect to a specific server, don't bother trying to
check for all possible problems that could prevent it; just try, and
report anything that goes wrong. If you just want to inform the user
whether their connection seems to be working or not, the best way
would be to try to ping a few hosts that aren't likely to all fail at
once (google.com, microsoft.com, etc) and see if you can get through
to any of them.
