I have 2 PCs networked thru a Linksys EtherFast® Cable/DSL Router with 4-Port Switch BEFSR41 with Comcast cable. Both PCs have thier own assigned IP address 192.168.1.100 and 101. Both operating with Windows XP, and a Realtek RTL8139 fast Ethernet NIC. Both PCs are on 24/7, but the .100 PC disconnects from the Internet, usually after it's been unused for awhile, while the .101 PC doesn't. Anyone have any ideas what it might be? I turned off all the Power Saving options in Windows.
