Hi Mohamad,

If you need to capture all traffic going through your modem then your best bet is to capture using a TAP between your WIFI routeur (WAN/Internet port) and that modem.

You'll then have all the traffic that is going to the Internet.

You won't capture traffic between the devices themselves.

Hope that helps.

Cheers,

JF

If your Wi-Fi router is the modem - i.e., if the modem has WAN, Wi-Fi, and possibly Ethernet ports - that obviously won't work. You'd have to capture in monitor mode, on some machine with a Wi-Fi adapter and an OS that lets Wireshark capture in monitor mode, to capture all Wi-Fi traffic between other devices and the modem/router, and, if it has an Ethernet port that's in use, you'd have to use a tap to capture all Ethernet traffic between other devices and the modem/router.
