Because it’s broken, your Vizio TV can’t connect to the WiFi. This can happen if the Internet speed of your router is too slow. And sometimes it’s because the DHCP setting on the TV is turned off.

11 ways to fix a Vizio TV that won’t connect to WiFi

1: Make sure your TV is hooked up to WiFi.

Technology is great, but it’s not always perfect.

Even the most high-tech gadgets can still have a glitch or bug in their system.

So, if your TV is acting up right now…

It’s possible that some of its settings changed on their own.

And that includes the WiFi you use.

Now, the first thing you should do is…

Check to see if your TV is still linked to WiFi:

  1. Use your Vizio remote to select Menu.
  2. Find the option for Network.
  3. Make sure your TV is hooked up to a network.
  4. If it’s not, choose your home network and sign in.

2: Turn on and off your Vizio TV

As was already said, glitches and bugs can happen in technological devices.

And while they only cause small problems with your device…

Small problems can add up over time and lead to bigger ones.

But the good news is that it’s easy to fix glitches and bugs on your TV.

All you have to do is turn off and on your device.

And it won’t have nearly as many of these problems.

“I don’t understand what you mean.”

Don’t be afraid. I’ll tell you what it is and show you how to do it step by step.


Power cycling means to turn off all the power to your device and then turn it back on.

And the way to do that is to unplug your device from the wall for a short time. Then, after the set time, plugging it back in.

“How is that different from using the remote to turn it off?”

The difference has to do with how much power is left on your device.

So, when you turn OFF your TV by pressing the power button or using the remote control,…

It’s just in standby mode, though. That means it’s still using power. And your TV is still on in the background.

On the other hand, when you turn your device off and on again…

You use up all the power it still has. This lets your TV stop whatever it is doing. While also getting rid of any problems that come with them.

Keeping this in mind, it’s time to…

Power cycle your TV:

  1. Use the TV’s remote or power button to turn it off.
  2. Unplug it from where it gets power.
  3. Hold down the TV’s power button for 5 seconds.
  4. Wait for 1 minute.
  5. Plug your TV back into the wall.
  6. Make it work.

Now, check to see if this fixed the issue.

3: Restart your router

Your TV isn’t the only thing that can break down or have small issues.

So, you can see that routers can also have too much to do. Even more so if a lot of devices are connected to it.

Now that you’ve done that, you should restart your WiFi router. So that it can work again with a fast and clean system.

Now, it’s important to note that most routers don’t have a specific button to restart or reset them.

But, just like with your TV, you can also…

Turn off and on your router:

Step 1: Pull the power cord out of your router.

You can do this at the wall outlet or on the unit of your router.

Step 2: If your router has a back-up battery, take it out.

After 10 seconds, put it back on the device.

Step 3: Wait for 1 minute.

Step 4: Plug your router back into its power supply.

And wait until all of the lights on the display of your router turn green.

Now, call your Internet service provider if any of the LEDs turn red or yellow.

But if all of the lights are green, you should go to…

4: Make sure your WiFi is working.

It’s possible that this problem isn’t coming from your TV. It’s also your WiFi network.

And the only way to know for sure is to…

Check to see if your Internet works on things besides your TV:

  1. Prepare a mobile device or a PC.
  2. Hook it up to the same WiFi network as your TV.
  3. Try using different ways to browse the Internet.

Now, if your websites or online apps don’t load…

Then you should talk to the company that gives you Internet access. And let them know that your router is broken.

But if your device can connect to the WiFi…

5: Find out how fast your Internet is

You can see that having a working Internet connection isn’t enough for your Vizio TV to work.


If your WiFi is too slow, your TV might not be able to connect to it.

Besides that…

The apps on your device also have their own minimum requirements for how fast your Internet has to be.

And if your WiFi is slower than what they consider normal…

Even if you’re connected to a network that works, your apps won’t load.

Now, to give you an idea of how fast your Internet needs to be, here are…

How fast your Internet should be to use some popular streaming services

Platform for streaming

Recommended Internet speed of some popular streaming platforms

Streaming platform Recommended Internet speed to stream on HD
Hulu 8 Mbps
Netflix 5 Mbps
Disney Plus 5 Mbps
Youtube TV 7 Mbps
Amazon Prime Video 5 Mbps


From this chart, you can see…

You would need an Internet speed of at least 5 Mbps to stream on apps like Disney Plus.

To use all of them, though, your WiFi speed needs to be at least 8 Mbps.

So you should aim for that number.

“How do I find out if I meet those requirements?”

It’s simple. Just do these things…

Check the speed of your Internet:

  1. Get a phone or computer ready.
  2. Hook it up to the same WiFi network as your TV.
  3. Open one of your device’s browsers.
  4. Go to
  5. Click the GO button in the page’s middle.
  6. Wait for the results to load.

You’re about to find out how fast your Internet is.

So, if your WiFi speed is at least 8 Mbps, move on to fix #7.

But if your number was less than that…

6: Take devices off your WiFi network

A slow Internet connection is often caused by a network that is too busy.

So, if you had Internet speed of less than 8 Mbps before…

Take other devices off of your WiFi network.

There are now two ways to do this:

  1. Manually.
  2. By changing the password for the WiFi.

You can, of course, disconnect each device from your network by itself.

But if you want to take the quicker way…

Change the password for your WiFi. In this way, all of the devices that are currently connected to your network will be cut off.

But keep in mind that this method also turns off the WiFi on your Vizio TV.

So, after you change the password, connect your TV to the Internet again.

Now, once you’ve disconnected most of your devices…

Recheck your Internet speed.

Still getting a speed that is less than 8 Mbps? Then, talk to your Internet service provider.

But if your WiFi is faster now…

Then give your Vizio TV’s apps another shot.

Still unable to load any? Then…

7: Turn on your Vizio TV’s DHCP settings.

Dynamic Host Configuration Protocol is a setting that can be changed on Vizio TVs (DCHP).

And simply put, this is to blame for…

letting your WiFi network know that your TV is a special device.

“You mean what?”

See, every device that connects to your WiFi gets a unique IP address.

You can think of these as your gadgets’ ID cards. And you already know that everyone should have their own ID.

Now, just like that, each device needs its own IP address.

Because if two or more things use the same 1,…

They won’t be able to use the connection to the Internet.

The easiest way to make sure your Vizio TV gets its own IP address now is to…

Turn on the DHCP settings on your Vizio TV:

  1. Turn the TV on.
  2. Use your remote to press the Home button.
  3. Go to Network > Manual Setup.
  4. Turn on the DHCP section by toggling the switch.

Note: If it’s already on, turn it off and on again.

8: Change the gateway on the router to WPA-PSK (TKIP)

Did you know there are different kinds of encryption on the Internet?

“What is it?

Encryptions are like the “locks” on your WiFi network.

Also, some locks are easier to use than others.

Some encryptions are also easier to use on Vizio TVs than others.

Also, it’s important to know that WPA-PSIK (TKIP) encryption works best with Vizio TVs.

So, if you still can’t get your gadget to work with your TV…

You should change your router’s gateway setting to this encryption. And the best way to do that is to call your ISP (ISP).


Changes to the encryption on your router pose security risks. So, ask your Internet service provider (ISP) what the pros and cons of using WPI-PSIK (TKIP) encryption are. And do the right thing.

9: Use a router.

This could be because of the WiFi feature on your TV.

So this time, you should use an ethernet cable to connect it to your router.

Not only could this fix the Internet problem with your TV, but it could also…

But it will also speed up the network on your device in general. Because ethernet is better than wireless connections.

“What’s better about them?”

Let me explain.

So, you can see that ethernet cables connect your router to your TV through a wired connection.

This means it won’t get messed up by other wireless devices in your house, like microwaves or cell phones.

Speakers with Bluetooth.

See, the signals from these devices can sometimes make it hard for your WiFi to work.

But if you use an ethernet cable, this will never happen.

On top of that, wired connections have less latency, which means your TV will work better.

This means that apps and websites will load faster on your TV. Which, if you ask me, is a very big plus.

With that in mind, here’s what you can do…

Use an ethernet cable to hook up your TV to the router:

  1. Disconnect your TV from the WiFi.
  2. Get a good ethernet cable ready.
  3. Plug one end of the cord into your router’s Ethernet port.
  4. Plug the other end of the cable into your TV’s Ethernet port.

Note: When you plug the connectors in, make sure you hear a click.

And once you’ve used an ethernet cable to connect your TV to the router…

Try streaming on any of your apps or browser again.

10: Reset your TV to factory settings

If you still can’t get your TV to connect to the WiFi…

Then you should try to reset your TV to factory settings.

Now, this process will delete everything on your device, including:

• Custom settings.

Installed programs and saved user accounts and settings.

But in the same way, it will also get rid of any glitches or bugs that are causing this WiFi problem.

But before you go on to the exact steps of this process, you should know.

Tip: Write down all of your apps, passwords, and custom settings. So, after you reset your TV, it will be easy to set it up again.

Having said that…

Here’s how to reset your Vizio TV to factory settings:

  1. Turn the TV on.
  2. Use your remote to press the Menu button.
  3. Select System from the list.
  4. Choose Reset and Admin.
  5. Choose Clear Memory from the menu (Factory default).
  6. In some models, this is Reset TV to Factory Defaults.
  7. Wait until the process of resetting is done.

Note: Don’t do anything with your TV while it’s being reset.

Not got a remote control? Watch this video to reset your Vizio TV to factory settings without a remote:

When your TV turns on…

Try again to link your TV to the WiFi. And the problem will probably be solved.

11: Contact Vizio support
