The only traffic you will see on your PC running wireshark is traffic to and from your PC. You will not see other traffic on the network, except broadcast packets. Switches have been common for decades. You had to go back to hubs or thinnet before the entire network was essentially broadcast and you could see everything. It was super inefficient and that is why we don't do that anymore. Only the router can see all the traffic to and from the internet. -- Len Sorensen
