I have a wired Ethernet network with Roku download speed of 35+Mbps. All devices are on the same wired network with 2-3 4-8 port gigabit switches to distribute the signals between rooms and devices. I upgraded my Premiere+ in the family room to an Ultra several months ago and it is working properly. I decided to take my old Premiere+ and add it to the network in my office. After adding the Premiere+ in the office, the Ultra in the family room says it has no internet connectivity. If I detach the Premiere+ from the network, the Ultra works fine. How do I get both to work on the same network.
