How do I monitor websites visited through my wifi?

edit

IMHO the best way is definitely to capture the information from the wifi router. Depending on the router, this information may not be freely available from the manufacturers firmware and installing a replacement firmware such as OpenWRT will allow the capture of the required information.

go to statistics, Endpoints and select the IPV4 tab. also ensure that your "name resolution is checked off"

Wireshark probably is not the best tool for this. Maybe try something like

Or maybe some type of proxy on the wired side that can log. In any case, managing wireless traffic, like this, with encryption is going to be problematic.
