I USED to have the Roku and my computer connected to the same switch (which was connected to my modem) and they worked fine together. After I disconnected the Roku from the switch to troubleshoot an Internet connection problem, the Roku won't connect to the Internet when the computer is also connected to the switch. The Roku OR the computer connect just fine to the Internet when it is one or the other but not when both are connected at the same time. I have a Dell computer - Netgear GS608 8-port switch - and a Roku Premiere +. Any ideas why they won't all work together anymore when they used to?
