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, Carol.
If you go into the setup menu on the appletv (settings menu, icon looks like a gear), then to network/wifi, does it show as connected there?
If so, let it "scan" or search for networks and see if it can find your home wifi network.
If it does, put in your password ***** reconnect.
If not, unplug power to both the atv and your router for 60+ seconds to reboot, then try again.
Let me know the results, and I'll advise further if needed.
