- 1). Press the "Menu" button on the remote, select "Network," choose "Manual Setup" and then select "Test Connection." If there is a problem with the connection, you will be notified and can begin troubleshooting.
- 2). Select your wireless network name from the "Wireless Access Points" list (even if you already did this before) and enter in the wireless security key for your network. The security key must be entered in exactly or you will not be connected. Press "Connect."
- 3). Log in to your wireless router's configuration menu (usually done by typing the router's internal IP address, such as "192.168.0.1," "192.168.1.1" or "192.168.2.1," into your Web browser's address bar) and disable the "MAC Address Filtering" option.
- 4). Go to the "Update" section of your router's configuration menu and see if there are new drivers, software or firmware available for your router. If there are updates available, follow the on-screen prompts to install them.
- 5). Double-check the wireless security key in the "Wireless Settings" section of the router configuration menu. The security key will be shown in its entirety in this menu and you can change it if desired.
- 6). Connect another device, such as a computer or iPhone, to your wireless network. If it is not able to connect, press the "Reset" button on the back of your wireless router to reset the wireless network. Once reset, the wireless connectivity problems should be resolved for both your Vizio HDTV and other devices. If you continue having wireless connectivity problems, your router's wireless networking may be defective.
- 7). Insert an Ethernet cable firmly into both the back of your Vizio HDTV and the "LAN" port on your router or modem and test the connection on your Vizio HDTV again. If you still cannot connect to the Internet, contact your router's manufacturer and/or your Internet service provider for further help.
