Edit: this will only report traffic going through the computer it's running on -- usually just traffic to/from that one computer. If you want to see traffic through the router from all hosts on the local lan, you need to set up some mechanism to have all of those packets sent to your capture computer. The WireShark documentation has a good discussion of the options for this.
