I have a wifi roku 3 4200X connected to my TV hdmi. It works fine. I have a Dell XPS13 and I have added the Roku device to my devices and printers. I have the Roku set to prompt or allow - doesn't work either way. I go to notification panel, click connect, click on the Roku device and after a while it tells me it can't connect. I get no prompt in prompt mode and no auto connect in allow mode.
