Well I have been beating my head into the wall for 3 weeks on this problem so hopefully you folks can help. The problem I am having is with the DHCP lease time. The current lease time is 24 hours. But everytime the lease expires I loose my network connection and have to reboot to restore it. I have tried the following to get rid of it: power cycling router, disconnecting cat6 cable, running IPconfig, and using the repair operation. All without effect. let me give you my system and setup info. I am running Win XP with a Realtek RTL8139/810X Family PCI Fast Ethernet NIC card connected to a linksys etherfast cable/dsl router (befsr41) connected to a RCA digital broadband modem. My pc is a athlon xp 2100+ system with 512mb ram. Anyone with any ideas?
