I have just installed a 5 port switch (Etherfast 10/100) so that I can run X-Box and my pc from my broadband modem. The X-box works fine, but my computer cannot detect a connection. I am running a straight cable from the switch to the PC, and my network repair function says it cannot renew my IP address. I have my computer set to detect IP address automatically. I've read through the forums and tried everything I could find that might apply. The lights are flashing or on on the switch, and I have tried plugging into different ports. ???
