Exact questions
Common questions about “Apple TV will not connect to Wi-Fi”
Can Ethernet help?+
If your Apple TV has an Ethernet port, a wired test shows whether wifi is the issue.
Should I restart the router?+
Yes, unplug the modem and router for 30 seconds.
What if only Apple TV fails?+
Forget the network, rejoin and check the router for filtering.
Which network band should Apple TV use?+
Choose whichever band gives the stronger signal at the Apple TV. Many routers combine both under one name, so you may need to check the router settings.
Would a wired connection be better?+
Yes. Apple TV HD and 4K models have an Ethernet port, and a cable avoids interference. If it works wired, the Wi-Fi link is the problem.
What if the network is not listed?+
Restart the Apple TV and router, move closer and check that the router is not hiding the network name.
Should I try another network?+
Testing on a phone hotspot shows whether the Apple TV can connect at all. If it works on the hotspot, the fault is in your home router or its settings rather than the Apple TV.
Would resetting the Apple TV help?+
A reset restores the Apple TV to its original settings and can fix stubborn network problems, but it removes your settings and apps. Use it after restarting, trying another network and checking the router have not worked.
