If someone is close enough to reach and hack my wifi for 5 hours, they have already been shot by me or my son....

So I thought that about us, also, but that little ESP32 picks up all kinds of remote stuff. I think these people are blasting wifi everywhere trying to get a strong signal. It carries pretty far.
To be clear, they just have to drive by once, then go home and take their time cracking it. When they come by again, they'll already have the password and can sign right on. It's actually like maybe 10/100 difficulty. Script-kiddie-level stuff.
I say "drive by" but they could do it very remotely with a popsicle stick and some paper clips for an antenna.
