I have been using a linksys hub for my network connections.....i'd basically run from the cable modem to the computer NIC, and then from another NIC to the hub and then to another computer. I decided to dig out my router and set it back up and I am having the same problems that I was before. It would work for a day or two and then I would lose all connection. I could still access the router's configuration but I couldn't ping any outside addresses. i'm using Windows XP Pro right now if it makes a difference and the router model is BEFSR41. It's just a basic 4 port router. Any computer added to the network is set to automatically obtain IP addresses. the only thing i can figure is that roadrunner uses a DHCP server and my router is set up for as the same. so whenever roadrunner renews the IP address through the DHCP, it's conflicting with the router....but I don't know too much about routers. When it goes down though, it doesn't come back up unless I go back to a regular setup with the cable modem going directly to the NIC. i'd greatly appreciate anybody's help with this. I need to use the router if possible.
