A network connection is required to use all SmartCast features, stream content from apps like Netflix, Disney+, and Peacock, and complete account setup at vizio.com/setup. Your VIZIO Smart TV supports both wireless Wi-Fi and wired Ethernet connections. For Wi-Fi, you can connect to either a 2.4 GHz band for broader coverage or a 5 GHz band for faster speeds — ideal for 4K and HDR streaming.

​
Connect via Wi-Fi

1

Open Network Settings

Press the Menu button on your VIZIO remote. Navigate to Network > Network Connection > Wireless.
2

Select Your Network

Your TV will scan for nearby Wi-Fi networks. When the list appears, select your Wi-Fi network name (SSID) from the available options.
3

Enter Password

Use the on-screen keyboard to enter your Wi-Fi password. Double-check each character carefully, then select Connect.
4

Confirm Connection

Your TV will test the connection automatically. A success screen will appear once your TV is online and ready to stream.

​
Connect via Ethernet (Wired)

1

Plug In the Ethernet Cable

Connect one end of an Ethernet cable into the LAN port on the back of your VIZIO TV and the other end into an available port on your router or modem.
2

Open Network Settings

Press the Menu button on your remote. Navigate to Network > Network Connection > Wired Ethernet.
3

Connection Detected Automatically

Your TV will automatically detect the wired connection. No password is required — once detected, your TV is online and ready to use.

​
Choosing 2.4 GHz vs 5 GHz

5 GHz offers faster speeds and less interference, making it the better choice for 4K and HDR streaming — but it has a shorter range and may not reach TVs far from the router. 2.4 GHz provides broader coverage and better wall penetration, but can be slower in areas with many competing wireless devices. If your router supports both bands, try 5 GHz first for the best streaming performance.

​
Troubleshooting Wi-Fi Issues

  • Confirm that your router is set to broadcast its SSID (network name) and is not hidden.
  • Try moving your VIZIO TV closer to the router to improve signal strength.
  • Restart your router by unplugging it for 30 seconds, then plugging it back in. Re-scan for networks on your TV.
  • Verify your Wi-Fi password by connecting a phone or computer to the same network.
  • When using the on-screen keyboard, check for accidental capitalization — passwords are case-sensitive.
  • Restart your VIZIO TV by unplugging it from the wall for 10 seconds, then powering it back on.
  • Restart your router and modem by unplugging them for 30 seconds.
  • Check whether other devices in your home have internet access to determine if the issue is with your TV or your internet service.
  • Switch from the 2.4 GHz band to the 5 GHz band in your Wi-Fi settings for faster speeds.
  • Consider using a wired Ethernet connection for the most stable and consistent streaming performance.
  • Check your router placement — walls, floors, and appliances can reduce signal strength.
For the best 4K streaming experience, use a wired Ethernet connection or connect to your 5 GHz Wi-Fi band.
