Answer 1

Come and ask, obviously.
1. I would use nmap on his IP.
See if there is anything open.
I would look to see if there are any sploits on open services at the ports, I would try to penetrate. would dig into it.
2. I would catch Wi-Fi packets, look where I go, what I do, what sites I visit. if VKont is active (and in any case it will get into the social network, then it’s already clear there, etc.

Answer 2

If the router has normal firmware, then tcpdump in your hands and go. And so - wireshark, but with it you will not see direct traffic between the router and the user.

Answer 3

I advise Wireshark, although it scares me from its appearance under the macos, but it performs its functions. You can also delete cookies :3

Answer 4

There is also kismet , but it is not easy, you have to figure it out.
