This weekend took a Roku box to my daughter at college. Thought it would be easy to do. She has one Ethernet jack in her room, so i brought along a Netgear 5 port Ethernet switch. One port to her Mac, and another to the Roku. The Mac works fine and the Roku shows connected but when we try to launch a channel we get an error message saying basically check your connection. So we check the college IT site and it says devices need to be registered, so we supplied the MAC address and submitted a request. Here is the email we got back: "Blank University does not support the ROKU so you must use your own documentation to setup the ROKU. If it is to go directly on the network, it must be set for DHCP, because RESNET is a DHCP network only". Now I know I'm going to have my daughter call their tech, but before that happens, anyone know what this means? How do I set the Roku to DHCP? At home I tested it and it hooked right up with my wireless router & tested it wired with the ethernet switch, all good. Reset Button and then connect again to switch? Any help would be comforting, she's not real tech savvy beyound plugging things in.
