I'm helping a friend out with his internet but I can't figure it out. It's prob. stupid that I'm overlooking but I can't figure it out. There is 2 computers, both are connected to the linksys router BEFSR41. The cable modem is connected to the router via the uplink port.

The weird thing is that the first computer that boots up, gets an ip of 64.xxx.xxx.xxx and the second computer that boots up gets the 192.1698.1.102

The first computer can access the web with no problem but the second one cannot. I know the onboard nic on the second computer is working since it can talk to the router, just can't access the web. And when we switch up which boot first, the first computer always gets to the internet.

I would expect that since both computers are connected to the router they should get the router ip, 192.168.1.xxx but it seems like the first computer that boots up is connected directly to the cable modem(based on the ip address), but both are wired connected to the router.

What's wrong, do I need a cross over cable or something between the cable modem and the router or is the router doing something weird?

Thanks in adv!

What kind of router? It almost sounds as if you have cable MODEM plugged into a hub instead of an actual router.

The router should get the 64.xxx.xxx.xxx external IP address, and an internal IP address of 192.168.1.1. The two computers should get IP addresses of 192.168.1.100, 101, 102, etc.

How exactly are the two machines connected to the router? Does it have several LAN ports?

This is the problem. The cable modem should be connected via the WAN port, not the uplink port. What appears to be happening is that one computer gets an ip via the cable modem, and the other gets an ip via the router's own dhcp server.

Yep...I missed that part you quoted. That explains it all.
