How can you tell if someone's using your wifi?
I mean besides if your computer is running slowly, because I already know that’s a sign someone may be.
I don’t want to know about how to secure your network, I’m just wondering how someone whose network was unsecured could tell if someone was using their wifi, if there is any way other than seeing that your computer is lagging.
