    Hello there, Gfucha.


    You might want to review the information in the following Knowledge Base article:


    Apple TV (2nd and 3rd generation): Troubleshooting Wi-Fi networks and connections



    Particularly the instruction found here:

    If you can see your Wi-Fi network, but you are unable to connect to it

    1. Check for any obstructions and adjust the location of your router or Apple TV; also check for sources ofpotential interference.
    2. Check the wireless security option of your Wi-Fi router.
      • If your Wi-Fi network uses a password, make sure you are entering it correctly.
        • Note: Apple TV cannot connect to networks that contain high (extended) or double-byte characters (Unicode) characters (such as Japanese, Korean, and Chinese) in the name or password.
      • If you are using WEP security, consider using WPA or WPA2 instead.
      • Temporarily disable wireless encryption or security on the Wi-Fi router to rule out encryption issues.
        • Note: Certain business and institutional Wi-Fi networks require special profiles to connect. See Additional Information below for assistance.
    3. Verify that your Wi-Fi router is not using MAC address filtering or other security features that limit the number or types of devices that can connect to it.
      • If you need to add the MAC address to the access list for the Wi-Fi router, the MAC address is listed as the Wi-Fi address in Settings > General > About.
    4. Update your Wi-Fi router to the latest firmware.
      • For an AirPort Base Station, refer to this article for information about firmware updates. For third-party Wi-Fi routers, check the manufacturer's website for details on updating your firmware.

    If after attempting the above steps, your Apple TV is still unable to connect to your Wi-Fi network:

    1. Restart your Apple TV: Choose Settings > General > Restart.
    2. If you can connect to the Internet using an Ethernet connection, verify that your Apple TV is using the latest software by choosing Settings > General > Software Update. If your Apple TV can be updated, install the update and test again.
