Hello there, fcwinkel42.

The following Knowledge Base article offers some great steps for troubleshooting your issue:

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

http://support.apple.com/kb/TS4546

The Basic troubleshooting steps (referenced partially here) may help:

1. Ensure that Apple TV is within range of your Wi-Fi router or base station.
2. Confirm that your Wi-Fi router and cable/DSL modem are connected to power and turned on.
3. Make sure other devices (computers, iPhone, iPad, for example) are able to connect to the Wi-Fi network and access the Internet.
4. Check your Wi-Fi network settings on Apple TV:
   • Choose Settings > General > Network > Wi-Fi and press the center button on the remote to display nearby networks.
   • Choose your Wi-Fi network from the list.
   • If your Wi-Fi network uses a password, make sure you are entering it correctly.
5. Restart your Apple TV by choosing Settings > General > Restart.
6. Try restarting your Wi-Fi router or modem by turning it off and then on again.

If possible, connect an Ethernet cable and verify your Internet connection. 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 then try the steps again.

Additionally, if the issues persists, then this section may prove usefull as well:

If you are unable to access or play content while connected to a Wi-Fi network

• Restart your Apple TV: Choose Settings > General > Restart.
• Verify that you are selecting the correct network if you are in a location with multiple Wi-Fi networks.
• Check the IP address that Apple TV is using. If it starts with 169.x.x.x, the router may not be configured properly.
  • If the router is using DHCP addressing, verify that the router is not limiting the number of devices that can connect through Wi-Fi.
  • If the router is using manual IP addressing, you will need to configure Apple TV with a manual IP address. You can do this by selecting your network on the Apple TV and choosing Configure IP.
• Disconnect and rejoin your Wi-Fi network by selecting your network on the Apple TV and then choosing Forget Network. Rejoin your Wi-Fi network after it disconnects.
  
• Verify that your Wi-Fi router is not using security features that may restrict content or devices:
  • If your router has a built-in firewall, you may need to adjust your settings to provide access to common ports used for services. For more information, see Apple TV: TCP and UDP ports and protocols.
  • 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.
• 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 possible, connect using Ethernet and verify that you can play content. If you are able to successfully play content using Ethernet, verify your Apple TV is using the latest software by choosing Settings > General > Software Update.

Note: When using a public or commercial network that requires a login or subscription, Apple TV may not be able to connect to the Internet. Check with the network administrator for assistance.

If you tried all of these steps and your Wi-Fi issues persist, contact Apple technical support or take your Apple TV to the nearest Apple Store or Apple Authorized Service Provider (AASP) for diagnosis. If you plan to visit an Apple Retail Store, make a reservation at the Genius Bar using http://www.apple.com/retail/geniusbar/ (available in some countries only).

Note: Diagnostic fees may apply for issues not covered under warranty or the AppleCare Protection Plan (APP).
