  • 1. WiFi network out of range

This happens to be one of the most common issues with almost everyone. You might not have a smart TV when you decided to get a WiFi router, or maybe you did not place it at the right place. This means the signals from the router cannot reach your TV.

If the signals reach the TV but very slightly, you would notice a significant drop in the video quality and an increment in the loading time until the TV disconnects from the WiFi due to the limited network range.

  • 2. Disturbance in the signal

If there are too many obstructing devices between the WiFi and your Television, you would face a constant disconnect error from your TV. This is because there are various electronic or opaque absorbing objects in the path.

Absorbing objects soak up a lot of radiation, so they would make it harder for the network to reach your television, making it disconnect multiple times.

  • 3. Multiple connected devices

There are two case scenarios in this. The first is that the WiFi router has so many devices connected that it cannot utilize the internet at all, thus it would consider the network ‘dead’ and disconnect from it. This might happen with your smartphone too, but with a warning.

The second scenario is when you limit connections. Several smartphones come with various options in the hotspot section. If you decide to limit the connection to let’s say two devices and two of them have already connected, then there is no way the TV would be able to connect to it.

  • 4. Illegal access

There is a slight but, still possible chance that someone broke into your WiFi network and has been eating up all the bandwidth. This brings us back to the previous situation.

The WiFi does not provide enough bandwidth to the TV and it believes the network to be dead, disconnecting from it, especially if it finds a better network nearby.

This one might sound troubling but do not worry, we have got solutions for it too!

  • 5. Wrong WiFi credentials

When you type in the WiFi password it is not necessary that it would be always right. We all make mistakes and typos are very common. If you are feeding the wrong password or changed the password, you would not be able to connect to it.

The TV works the same way as other devices do. You need to update the password and credentials once you have updated them on the WiFi router. If you do not, this error would keep on happening until you fix it.

These were the reasons we most definitely believe are behind the Vizio TV keeps disconnecting from WiFi network issue. We are going to focus on how to fix them now.

How to fix Vizio TV keeps disconnecting from WiFi

  • 1. WiFi Router location

The first and foremost step that would immediately ensure that you fix the issue number one and two mentioned above is to place the router at a place where it’s network can reach the TV easily.

I would advise you to try keeping it in a high place with less absorbent or opaque materials around.

  • 2. Monitoring your WiFi

This can be easily done via the WiFi router login page. For most routers, it is but some also make use of Noting down the MAC address that does not belong to your devices and blocking them would be of great help in protecting against hackers.

  • 3. Device connections

The last step I would suggest is to take a look at your hotspot settings if you have been using your smartphone as a WiFi hotspot. If not, check for the maximum number of connected devices on your WiFi router.

There are only a limited number of devices that can connect to a router. If the number exceeds this, disconnect some devices and try to connect your TV again.

  • 4. Check internet speed

Anothe reason your Vizio TV keeps disconnecting from WiFi could the low internet speed or fluctations of the internet.

You can test the speed of the internet on fast.com or speed test by Ookla.

If the speed is too low or is fluctating, you should contact your ISP (internet service provider) to fix the issue.

  • 5. Change DHCP Settings

DHCP (dynamic host configuration protocol) makes the connection strong between two devices by  assigning dynamic IP addresses to devices that are connected to the network.

To turn on the DHCP on your Vizio TV, follow the steps below:

  1. Press the Menu button on the Vizio remote.
  2. Select Network > Manual Setup > DHCP.
  3. If DHCP is set to OFF, press the right arrow to turn it on.
  4. If it is set to ON, press the right arrow once to turn it off, and then again to turn it on.

  1. Vizio TV
  2. WiFi router and 
  3. Modem

So, start rebotting your device and give them a fresh start. Make sure to wait for atleast 2-5 minutes before turning on each device.

Once all the device are turned on, trying connecting the Vizio Tv with WiFi and check if it is working fine now or not.

  • 7. Enable WPA-PSK [TKIP]

Next thing you can try is to enable to enable WPA-PSK [TKIP] security setting of your WiFi router.

Vizio TVs work best when WPA-PSK [TKIP] encryption is  enabled.

Enter the router’s default gateway IP address into the URL bar of any web browser to access the router settings.

This might seem quite technical for many users, but its not too complicated. You can also reach out to your ISP to enable these setting.

  • 8. Try Wired Internet Connection

If still your WiFi connection isn’t stable on your Vizio TV, you can try connection the WiFi router directly to the TV if your it houses an Ethernet port.

If now your Vizio TV has a stable internet connection, it could be that your TV’s wireless adapter has some issues.
