If you’re a regular TV viewer, you’ll know how frustrating it is when your TV doesn’t connect to Wi-Fi. Without an active connection to the internet, you won’t be able to stream your favorite shows or movies. TVs not connecting to Wi-Fi are not uncommon, and Vizio TV is no exception.

Vizio TV not connecting to Wi-Fi is a network or settings issue most of the time. It could also be caused by a software glitch or a faulty TV Wi-Fi adapter. In most cases, the problem can be resolved with simple steps such as restarting the TV and modem or changing the router’s security settings.

If you’ve got a Vizio TV that won’t connect to Wi-Fi, you’re in the right place. Read on to learn more about why your TV won’t connect to Wi-Fi and how you can troubleshoot and resolve the issue.

Why Vizio TV Won’t Connect to Wi-Fi

Vizio TVs are smart devices, and you need a high-speed internet connection to make the most of their features. Wi-Fi enables the TV to connect to the internet cost-effectively.

Without Wi-Fi, you won’t be able to stream TV shows or movies from streaming companies like HBO Max, Netflix, Hulu, Disney, and Amazon Prime. How frustrating that can be for a movie-lover!

There can be several reasons why your Vizio TV won’t connect to Wi-Fi, from internet connectivity and network issues to software or hardware glitches in the TV, modem, or router.  

Your Internet Connection May Not Be Working

A disruption in your internet connection can cause your Vizio TV to disconnect from Wi-Fi. This internet downtime can happen for several reasons:

  • A loose cable.
  • An unplugged modem or router.
  • Modem or router remaining in standby mode for several days or weeks.
  • A software glitch or system error.
  • A service outage at your internet service provider.

You May Have Entered an Incorrect Password or Network Key

If you bought the Vizio TV recently and are trying to connect it to Wi-Fi for the first time, you must select your Wi-Fi network and enter a password or network key. 

Some people tend to forget the password for their network since they had set up the Wi-Fi connection several months or years ago. If you enter an incorrect password, your TV will not connect to Wi-Fi.

After the first sign-in, Vizio TV, like most internet-enabled devices, will connect automatically to your Wi-Fi network.

The Router’s Security Settings May Be in Conflict With Vizio TV’s

All routers have security settings to prevent malware (malicious software) from infecting your network and devices. If malware gets to your devices, hackers can see messages you send over the internet and even steal your sensitive personal data and information.

However, some router security settings may be in conflict with Vizio TV’s.

The TV’s Wi-Fi Adapter May Not Be Working Optimally

Vizio TV has an in-built Wi-Fi adapter that receives signals from the router. If the adapter is not working properly, the TV will not connect to Wi-Fi.

Walls or other concrete or metal structures between the router and the TV could block or weaken the signals, preventing the Wi-Fi adapter from working optimally.

Vizio TV Not Connecting to Wi-Fi: A Troubleshooting Guide

Now that we know why Vizio TV won’t connect to Wi-Fi, let’s look at how we can resolve the issue. Fortunately, there’s a troubleshooting sequence you can follow to fix the problem.

In most cases, you can reconnect your Vizio TV to Wi-Fi by performing these simple troubleshooting steps:

1. Check Your Wi-Fi Settings

The first step is to check whether other devices like your smartphone or laptop are connected to Wi-Fi. If they are, the issue could be with your TV’s Wi-Fi settings.

Here’s how you can check the TV’s Wi-Fi settings:

  1. Press the Menu button on your TV remote control.
  2. Go to the Network option and press the OK key. You’ll see a list of available Wi-Fi networks and the network your TV is connected to.
  3. If the TV is not connected to any network, select your network and enter the password or network key. That should do it.
  4. If the TV is connected to your network, disconnect it and reconnect it after one minute.

2. Reboot the TV and Router

Rebooting an electronic device often helps to resolve temporary software and hardware glitches. Rebooting essentially involves shutting down the power supply to the device and then turning it on again.

Rebooting will clear Vizio TV’s internal memory, reinitialize its configuration parameters, and help it recover from a “hang” situation. Rebooting involves just a few simple steps:

  1. Turn off the TV and router.
  2. After one minute, turn both devices on again.
  3. If the issue persists, turn off the TV and router and unplug them from their power sockets.
  4. Press the Power button on the TV set (not the remote) for about 30 seconds to drain all residual power.
  5. After another 30 seconds, plug in the TV and router and turn them on.

3. Change the Router’s Security Settings

If the rebooting didn’t make a difference, try changing your router’s security settings. They may be in conflict with Vizio TV’s settings. The setting that works best with Vizio TV is WPA-PSK with TKIP encryption.

You can use your computer or smartphone to change the router’s security settings. Enter the router’s IP address into the browser bar to access the settings page.

4. Check Your DHCP Settings

The Dynamic Host Configuration Protocol (DHCP) helps devices communicate with the router. Turning it on will help your TV work better with the router.

To turn it on:

  1. Press Menu on your Vizio TV remote.
  2. Select Network > Manual Setup > DHCP.
  3. Turn on DHCP.
  4. If it’s already on, turn it off and then turn it on again.

5. Use an Ethernet Cable To Connect the Modem or Router to the TV

If your Vizio TV still cannot receive data signals from the router, the problem could be with the TV’s wireless adapter.

Try connecting the modem or router to the TV with an ethernet cable. If the TV can connect to the internet, that’s confirmation that something is wrong with the wireless adapter. You need to call Vizio Support to service or replace the adapter. 

6. Reset the TV to Its Factory Settings

If the TV won’t connect to Wi-Fi even with the ethernet cable, the next step is to reset it to its default factory settings. The reset will take your TV back to the state it was in when you bought it.

You’ll lose all your downloaded apps and saved programs, but it will also clear the system of all bugs and glitches.

Here’s how you can reset the TV:

  1. Press Menu on the TV’s remote.
  2. Using the arrow button, navigate to System and press OK.
  3. Select Reset & Admin and press OK.
  4. Select Reset TV to Factory Defaults and press OK.
  5. If the system asks for a password or code, key in 0000 (four zeros).
  6. Select Reset and press OK.

The TV will restart and initiate the Setup App process. 

7. Contact Vizio for Support or Service

If none of these troubleshooting measures work, then it’s time to call in the experts. You can request a callback from a Vizio Support representative or submit a service request for your TV. You’ll need to provide them with your TV model and serial numbers.

Final Thoughts

Like all smart TVs, Vizio TV may disconnect from Wi-Fi for various reasons, disabling many of its features and functions.

However, all it usually takes is a few simple steps to connect the TV back to the internet. Just perform the troubleshooting steps one by one, and you’ll likely binge on your favorite movies again in no time.
