Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
You have to get the roku onto your home network first.
Turn the tv on, set to the proper input mode to pick up signal from the stick, then you'll be prompted to use the roku remote to configure it to your home wifi network. Only after that step is done will it bring up an activation code on the tv screen, which you'll then enter in the registration page on roku.com on your computer.
