I'm running my cable modem through the uplink port on my lynksys 8 port 10/100 hub (it's actually a switch). Everything works OK initially (all 4 of my PC's can get onto the net simultaneously. Good pings in Q3, et) ,but after they sit idle for a bit (20 minutes - 1 hour or so), they lose their connection to the internet. A simple reboot is the cure, but it's a pain. Any ideas why? And if it's so easy to share cable with a switch or a hub, what's the point of getting a router? Thanks!
