Wireshark and cable modem

0

Hi, my computer is behind cable router. I wander is it possible to capture all of the traffic that comes to my router with wireshark? I want to sniff the traffic before my router. I read something about promiscuous mode, but the problem is that I only see my own traffic.

Start off with the capture setup, then work your way towards the WAN interface.
