    I have seen it happen. Especially if someone is using MAC Cloning.

    Yes, but if two devices end up on a network with the same IP address, at the same time, they will knock each other off of the network.

    That can happen. But I have also seen where both have stayed online. But could not do anything, due to the router/gateway/modem ARP table was hosed.

    Either way it won't work, you can't have two devices on a network at the same time with the same IP address.

    Like I stated above. I have seen it happen when the ARP table in the gateway/router got hosed up. Clear the table, and everything went back to normal.

    Yes but they can't use the network, that's my point. You could if you wanted to, set two PC's up with identical static IP addresses. Turn them both on at the same time, on the same network and they'll knock each other off of the network.

    If the router is working properly. You are not hearing me through what you want to see and hear. The OP problem is with their Network equipment and possibly the NIC's. They have not been back. So most likely will never know what their problem was, since they were never distinct as to what their network infrastructure is.
