I am trying to network 2 PC's together using linksys nh1005 5 port hub. The problem I get is when I turn both PC's on at the same time I get a IP address conflict. I have determined that my modem (At&t sbc yahoo dsl) is the problem because it is main IP address that both use. I have tried and tried to access the router using various IP addresses (I can access my modem at 192.168.0.1) but have had no luck. I read on the linksys site that the router may be 192.168.15.1, but that hasn't worked and neither has 192.168.1.1. I have also tried to apply a static IP address but to no avail. I think this is because I can't find the actual IP address that the router is on. Right now my IP address is 192.168.1.64 which is in the range that I need, but if I were to turn the other computer on I would get IP's in the 70.140.x.x range, which I have been told should be impossible. I called the ISP, and they told me that the only way they could continue to help me was for me to call the tech support help line, which costs money per call. I want to avoid this call because I am fairly competent in computer (I used to mess around in DOS all the time back in the day...) and am hoping to find someone to help via the internet. One last question, and this relates to the static IP's... Do you have to reboot the computer between assigning static IP's or not? I doubt this is the reason, but the simple answers are usually the correct ones.... Thanks for your help.
