Vizio TV Won’t Connect To WiFi? Get Help Now

What To Do When Your Vizio TV Isn’t Getting Along With Your WiFi

Vizio manufactured some of the first generation models of smart TVs, yet the brand’s superb quality is not immune from network connectivity issues. When your Vizio TV won’t connect to the WiFi, you cannot stream online entertainment. In addition, the TV won’t get updated. What causes this?

Your Vizio TV not connecting to WiFi is caused due to the incorrect network configuration. This problem prevents you from enjoying online content on the bigger screen. This can be fixed by troubleshooting the network configurations on your TV. 

Before watching or exploring the internet content, you have to set up your Vizio smart TV. However, connecting to the WiFi is considered the first step while setting up the TV correctly is also important. In this guide, we will detail exactly how you can fix this common issue. 

Who Makes Vizio TVs?

Vizio TVs are designed in California, but they are made in Vietnam, China, Taiwan, Thailand and Mexico. That’s because Vizio outsources manufacturing to companies like BOE, Foxconn, Innolux, KIE, Tonly, TPV and Zylux. 

These manufacturers purchase the necessary components and assemble Vizio Smart TVs within their respective facilities. So while Vizio is an American publicly traded company and they are their own brand, all of their manufacturing is done outside of the United States.

My Vizio TV Won’t Connect to WiFi: Why Not?

There are various reasons why Vizio smart cast cannot connect to the WiFi. But it could just be that your internet connection may have problems. There may be an issue with WiFi and your smart TV itself. For instance, both the router and TV may also have connection problems.

Despite many reasons preventing Vizio smart TV from connecting to the WiFi. There are solutions on how to resolve the issues on your own.

First of all, you have to check if your internet connection is working or not. To do that you have to perform the speed test of your WiFi connection. Open a web browser and then search for Fast.com. What this essentially means is that you can use another device to test the internet speed.

If the internet connects to your device, the problem is with your Smart TV. However, if the internet does not work on other devices then, try resolving the WiFi network.

Power cycling simply turns off your device until the power is drained. In addition, power cycle all the devices which are linked with the TV– i.e TV and the router. 

Follow these instructions step-by-step to perform a power cycle: Turn off your Vizio smart cast tv and unplug it. Then, go through these steps:

  1. Disconnect the router and modem from the power source as well.
  2. Wait for 5-10 minutes.
  3. After that, replug your SmartCast TV to the wall socket.
  4. Same as for the router and the modem.
  5. Turn on the TV and then check if the error is gone or still exists.

DHCP stands for Dynamic Host Configuration Protocol which assigns IP addresses for each device on the network. The IP address is unique for each device in the network. However, sometimes two or more devices have the same IP address.

That prevents the internet from working and WiFi from being connected. Enabling the DHCP on your device prevents such errors from occurring. To do that:

  1. On your TV, remote, press the Home button.
  2. Go to Network and then select Manual Setup.
  3. Select DHCP and then check the enable option.

Sometimes, there are a lot of devices connected to the same network. It makes the network busy and the TV cannot connect to the WiFi. To fix the issue, you have to change the WiFi password from the router.

Open your router’s Cpanel and then change the password. After that, enter the WiFi network password to join the connection.

The network configuration on Vizio SmartCast TV works best with WPA-PSK [TKIP] encryption enabled. To reset the gateway setting, you have to consult with your ISP.

There are different ISPs so changing or resetting the router gateway setting may cause problems. I recommend asking your ISP to change the router encryption type.

If your Vizio SmartCast TV has an ethernet port on its backside, connect it directly to the router or the modem with an ethernet cable. If your TV gets an internet connection via ethernet cable then the TV’s wireless adapter is broken. If all else fails, you can factory reset your smart TV.

Why Won’t My Vizio TV Stay Connected To WiFi?

One of the main reasons could just be that your broadband connection isn’t particularly good. This isn’t a reason anyone wants to hear, but it’s definitely a possibility.

If your WiFi isn’t strong enough to maintain a connection with your smart TV, then it may disconnect from it altogether. You might notice this more if you’re streaming in 4K quality, as this uses more bandwidth to stream than streaming in 1080p. 

In this case, you can toggle DHCP settings.

Toggling the DHCP setting off and on can sometimes fix internet connection problems. In layman’s terms this setting helps your TV understand how to use your WiFi router to access the internet.

How To Toggle DHCP Settings

  1. Press the Menu button on the remote
  2. Go to “Network” and press OK
  3. Select “Manual Setup” and press the OK button.
  4. DHCP is listed at the top of this page and it will usually say “On” next to it. Press the arrow button on the remote that points to the right to turn it off. Then press the arrow button that points to the left to turn it on again.
  5. Test the network connection again

When checking DHCP settings you might find that it is already turned off. This might be the cause of your internet problems. Turn DHCP on then test the connection again.

If you see a download speed after testing the internet connection again you will be able to use your apps.

Test The Internet Connection From A Second Device

Test The Internet Connection From A Second Device

Whenever there is any type of internet connection problem you want to determine if the problem is limited to a single device or if all the devices connected to the network are having the same problem.

You will want to use another wireless device like a laptop, tablet, or smartphone. Check the WiFi settings of the device to see if it’s connected to the same network the TV is using.

Use the wireless device from the same location the TV is in. Use it in the same room and open a new website. If your second wireless device is not able to open a website then this is a problem with your WiFi network and not a problem with the TV. Contact your internet service provider to get help restoring your internet access.

If your second wireless device is able to open a new website then you have determined that the problem is the Vizio TV and not your home network.

Vizio TV Keeps Disconnecting From WiFi

Now, if there’s nothing between your router and your smart TV, then we can begin to look at other possible causes of the problem. 

There could be a whole host of other reasons where your router is at fault. You’ll want to check that your router isn’t near another device that could be causing interference – baby monitors are common culprits for this.

Other things you should check include the time on your TV, which could be causing your router confusion. And, simplifying your WiFi SSD is a good idea for this too.
