Not much to go on in your question. PLease elaborate more on what you want to achieve and what your network looks like. (What hosts? what sort of network? switches? routers?)

since it is a switched network you might get into issues. Best solution is to connect directly to the router or mirror on one port of the switch the rest of the ports. Then get to the filters of the wireshark and type

ip.addr == && ip.addr== is the router IP and is the PC IP.

As you're most likely capturing on a switched network capturing on two other devices isn't trivial, see the Wiki page on Ethernet Capture setup, particularly the sections on switched networks.
