I want to set up two networks in my house. One will be a "public" wireless network for any guests in our house to use. The second will be my personal home network (Windows XP workgroup). I do not want the "public" wireless network to see, let alone access, my personal home network. I would like to use 1 modem and two routers to accomplish this. My initial thought is to connect the wireless public router to the modem and connect the router for the home network to the wireless public network, setting up a firewall on the home network router to block access from the public wireless router. Any thoughts?

See if your broadband provider will provide you with a second IP address that way you can hook up a 4 port Ethernet hub or switch and then hook up your routers to the hub/switch. One router will handle your secure windows workgroup network use WPA 2 professional with AES, that will give you the best protection. Then use some flavor of WPA for your public Internet router so that your guests can get online but those outside your home can't mooch your Internet service. http://www.bill-mcminn.com/pchelp/h...
