Thank you for visiting Apple Support Communities.
Sometimes a simple power cycle of the Apple TV and your wireless network resolves this issue. However, if the issue persists, try the steps in the attached section of the article below.
If you're not able to associate with a wireless network:
- Check the IP address Apple TV is using. If it starts with 169.x.x.x, then the router or base station may not be configured properly. Check to see if DHCP access is available or configure Apple TV with a manual IP address.
- If DHCP is available, go to Settings menu, select General then Network and Configure TCP/IP. Make sure the Apple TV is set to Automatic.
- Check for any obstructions and adjust the location of the base station and/or Apple TV if necessary.
- If security is enabled on the network, temporarily disable it on the base station and try connecting again.
