How to monitor connections via wi-fi?

Question

Computer networks

If they connect to my router via wi-fi, can I monitor what sites they go to and what they download without installing additional programs for those who connect?

Answer 1

Yes, direct your traffic through a local proxy server. Any proxy server can log requests. Only with https sites, you can't get anything else url

Answer 2

Technically, you can set it up, whether you can set it up is another question. Many alternative firmware for routers contain this functionality out of the box.
