Wireshark isn't really the tool to do this, it's a packet analyser, not a network monitor, although if you could arrange to capture ALL traffic for EVER, and then have the ability to analyse the possibly very large capture files, it might be made to work.

To capture ALL the traffic you'd need to run the capture on your router, which probably won't be able to run Wireshark, but might be able to run tcpdump, or a similar router utility, to capture traffic. You could then export the captures to a local machine to analyse with Wireshark (or other tools).
