How to Fix Your Vizio TV When It Won't Connect to Wi-Fi

Fix your smart TV's Wi-Fi capabilities

You sit down at the end of a long day to catch up on Stranger Things only to receive the dreaded message from your smart TV: network not found. Vizio televisions sometimes lose connection to your network for no explainable reason, and the solutions can be almost just as obscure. Thankfully, we've gathered up the best fixes to get your Vizio TV connected to Wi-Fi so you can get back to binge watching your favorite shows. Here's how.

Check that the Wi-Fi network is up.

No Wi-Fi on Visio TV

Before you begin to diagnose potential problems with your television, make sure your Wi-Fi network and router are operating properly. 

  1. If your router has indicator lights on the front, make sure they are all lit and flashing (or solid if that's how your router works).

  2. Find a laptop or smartphone and make sure it is connected to the same Wi-Fi network as the TV.

  3. Try to open a website or run a speed test. If the device connects, then the problem lies with the television. If the other device does not connect, then you may need to troubleshoot your internet connection.

How to Power Cycle Your Router and TV

Your Wi-Fi connectivity issues might be solved by resetting your router and reconnecting. Here's how.

  1. Turn off your television and unplug it. 

  2. Unplug the power cable from your router and leave it unplugged for at least sixty seconds.

  3. Plug the router back in and wait for all of the lights to come on. This can take up to ten minutes.

  4. Plug your television back in.

  5. Go to Settings > Test Connection. If a download speed appears, it means your TV is now connected to the internet.

Leaving the router unplugged for thirty seconds clears its internal memory and helps to clear any software glitches that might result in poor connectivity. 

How to Toggle DHCP Settings

If none of the above steps have resulted in a Wi-Fi connection, you may want to try toggling your DHCP settings. DHCP stands for dynamic host configuration protocol, which is a fancy way of saying that it helps your TV and router play nicely together. Here's how to toggle the setting.

  1. Press the Menu button on the remote.

  2. Select Network from the Menu options.

  3. Select Manual Setup.

  4. Select DHCP. Beside it will be the word On or Off. If the setting is set to OFF, press the right arrow to turn it ON. If ON, press the right arrow once to turn it OFF and then again to turn it back ON.

  5. Test out your connection.

In most cases, the DHCP setting should be on. Toggling this setting will often restore your connection when the television loses it.  

Change Your Router Settings

In some cases, the problem isn't a malfunction with the TV or the router, but instead a conflict with the router's security settings. These settings exist to prevent malicious software from gaining hold in your router or to block access to your network.

For example, one of the most common ISPs in the country is Comcast. Their standard router is the Arris TG862, which has built-in security that conflicts specifically with Vizio TVs. The way around this is to change your router setting to WPA PSK TKIP. You don't need to worry about the meaning of the acronym (it's short for the official title of the network setting), but you do need to find out how to change your router's security.

If your router is provided by your internet service provider, call them and ask how to change the security settings. If you use your own router, refer back to the owner's manual. There are several options to choose from, but Vizio TVs work best with the WPA PSK TKIP setting.

 On most routers, the process will look something like this:

  1. Open a web browser on a laptop computer or a desktop and type into the URL bar. This will open the router login screen.

  2. The login name and password often default to "admin" and "password." Try these. If they do not work, try the network name and password for your Wi-Fi network.

  3. Once you log in, look for an option titled Connection on the screen and select it.

  4. Select Wi-Fi > Edit

  5. This opens up the Wi-Fi Settings menu. From here, you can change the name of your network and modify the security settings. Look for the option to swap your router to WPA PSK TKIP and select it.

  6. Save your changes and log out.

Once you do this, you may need to power cycle your television (refer to the above section of this article titled "How to Power Cycle Your Router and TV" for instructions) before it will connect to your router. In many cases, however, changing this security setting makes it easier for your TV to connect to the Wi-Fi. 

How to Reset Your Television to Factory Defaults

If all else fails, you might want to reset your TV to its factory settings. This will wipe it clean of any internal data and make it act as though it were brand-new again. However, it will lose all information about your saved usernames and passwords. You will need to enter all of this information again after you reset the TV.

  1. Press Menu on your remote.

  2. Go to System > Reset and Admin.

  3. Select Reset TV to Factory Defaults and press Okay.

  4. Select Reset once more. 

The television will turn itself off and then come back on at the original setup screen. The startup guide will appear and guide you through the process of setting up the TV, which will often solve any connection issues that existed prior to the reset.

If all else fails and your television will not connect to Wi-Fi, an Ethernet cord will solve most of the problems via a direct connection.
