Is your Vizio Smart TV not connecting to WiFi, and you can’t figure out why? We’ve got you covered. 

Your Vizio TV needs an active internet connection for updates and applications like Netflix and Hulu. While you can use an Ethernet cable to connect the TV directly to the router, a WiFi connection gives the setup a cleaner look by ditching the cable. However, sometimes, your Vizio TV can fail to connect to the WiFi, even if everything was working smoothly a minute ago.

In this guide, we’ll explain why your Vizio TV isn’t connecting to WiFi and how you can fix it quickly.

Why won’t my Vizio TV connect to WiFi?

Here are some possible reasons your Vizio TV isn’t connecting to WiFi.

  • Internet outage or maintenance 
  • Issues with the router
  • Outdated TV firmware 
  • Router’s security settings
  • Faulty TV WiFi adapter

How to fix a Vizio Smart TV that won’t connect to WiFi

Here are some methods that can help you fix the issue. 



Check for internet outage

Before moving on to any troubleshooting methods, ensure that there isn’t any local outage or ongoing maintenance in your area. You can contact your ISP or visit their website to learn about the current status of the network. If there is something going on, there’s nothing you can do except wait.



Power cycle your Vizio TV and internet router

Sometimes, a bug or glitch can prevent the connection from getting established. The best way to get rid of such bugs or glitches is by power cycling the devices.

  1. Turn off your Vizio TV and internet router.
  2. Remove the power cables from the devices and power outlets.
  3. Wait for around three to four minutes before plugging them back in.
  4. Wait for another four minutes before turning the devices back on.



Adjust the DHCP settings

Your Vizio TV might not connect to WiFi due to incorrect DHCP settings. This basically allows the TV and router to establish a connection and work together. 

  1. Access your TV’s main menu.
  2. Go to Network. 
  3. Select Manual Setup and then choose DHCP.
  4. Turn DHCP on if it is off.



Adjust the router’s security settings

Another possible reason behind the issue can be your router’s security settings. You need to access your router’s admin panel, which can be done by typing in the default IP address in a web browser. Once in, go to the security settings and enable WPA-PSK [TKIP].



Reset your Vizio TV

If nothing seems to work, your last option is to factory reset your Vizio TV to clear out any bugs, glitches, or other software-related issues that may be causing the problem. Keep in mind that factory resetting your TV will remove your custom settings and apps, so you’ll have to set it up again from scratch.

  1. Open the Main Menu.
  2. Go to System and select System & Admin.
  3. Choose Reset TV to Factory Defaults and wait for the process to finish.

Why does my Vizio TV always disconnect from WiFi?

Your Vizio TV may keep disconnecting from WiFi if there is a problem with your internet connection or you’re running the TV on outdated firmware.


It can be annoying to see your Vizio TV not connecting to WiFi. But instead of panicking, try troubleshooting the issue yourself by power cycling the devices. If it doesn’t work, move on to the advanced solutions. But if the problem isn’t going away, you’ll need to contact Vizio support for further assistance.
