I've recenlty upgraded my home network by purchasing a linksys WRT54G2 wireless router. My kids both have laptops with wifi cards and hook up to the wireless router. I want to use wireshark to monitor what my kids do on the internet. I'm familiar with wireshark but not familiar with the exact network setup I need to get all the network traffic to my monitoring laplop. I've gathered from my googling that I can add another router and a hub to my setup, but I need details on how I'd do this. Is this correct? What brand and model do I need to buy at best buy or ebay?
Sorry if this question is so open ended, I'm not really sure what to ask to get to the end result I'm looking for, so any other ideas would be appreciated. Like I said, I'm building this little network from scratch, so I can do pretty much anything I need to do.
