That's right.
In fact, I generally start a ping to a remote IP address after bootup
and, if I don't get any response (which is always the case), I start
tcpdump and I do some network activity before stopping it.

In fact, I ran tcpdump to check what was going on and, since it "solved"
the problem, I didn't check for a better way to do it.
Obviously, your solution is better.

Hopefully, there is some periodic network activity on my machine (at
least checking of my POP account), so it doesn't break.
