This isn't necessarily a solution - maybe the OP merely wants to display a
"network available" indication at the start-up of an app, in which case
there is no particular operation to be performed.

The only real solution, as you pointed out, however, involves performing
network activity, but I would suggest performing an idempotent operation
from a well-known address. For example, maybe you can connect to the
telnet/ssh port of a local server, or make a DNS query, or query an NTP
server, or similar.
