Vizio TV Keeps Disconnecting from WiFi: How to Fix [2023]

Lately, I have noticed that quite often my Vizio TV won't connect to WiFi, and keep disconnecting after some time.

Although I use a Roku with my Vizio TV for my multimedia needs, it's still weird that my TV doesn't sustain its connectivity to my network for long.

After experimenting with all settings available on the TV, as well as scouring through some key threads and forum posts, I feel I have come to a logical way forward with this situation.

If your Vizio TV keeps disconnecting from WiFi, hardwire the TV using an ethernet cable for best results. Next, check the position of the internet router with respect to the Vizio TV and the obstacles in between. You could also try turning off CEC, Eco mode, and guest mode before performing a power cycle and a factory reset.

Hardwire the Vizio TV

Unfortunately, this is quite a common occurrence with Vizio TVs, according to plenty of users on Reddit and Vizio forums.

Users suspect either a design flaw or an inferior WiFi modem inside Vizio TVs for this error.

This might seem a bit farfetched for the common folk, as Vizio is a reputed brand that has been making quality televisions for quite a long time now.

But with the smart TV revolution, plenty of manufacturers have resorted to using inferior internal components in order to cut costs.

This is the primary reason why many face issues with lagging UI features such as the TV being stuck on the Vizio logo and in some cases even sound delays.

People resort to using external media players such as Roku anyways, so it's not like users don't have options to upgrade down the line, but I digress.

One of the most effective ways to get around frequent WiFi disconnections is to simply hardwire the TV using an ethernet cable.

This at first glance can seem like a rudimentary step that completely negates the purpose of using wireless connectivity in the first place.

But it is a fact that wireless communication standards like WiFi will always be inferior to wired communication standards like Ethernet.

It not only removes factors such as obstructions, but it also enables proper utilization of your internet plan's speeds.

To hardwire your TV, all you need to do is pull an ethernet cable from your internet router to your Vizio TV.

Check the Hardware and Positioning of Vizio TV and Internet Router

If you are adamant about using WiFi for your Vizio TV, then you might wanna check on the positioning of the Vizio TV with respect to your internet router.

For WiFi to work best, you will need to be as close to the router as possible. The same applies to TVs.

Although hard to realize, ensure that your TV and internet router have as little distance between them as possible.

Try to find ways to get over obstacles in between the devices so that you get the best link speeds and connectivity possible.

Check the Internet Connection

Checking your internet connection might be one of the most obvious steps to take.

Aside from the usual steps such as checking with your internet service provider if your internet is working properly, there are a few key areas you might need to guide your concerns to:

Toggle DHCP Settings

Dynamic Host Configuration Protocol (DHCP) helps assign IP addresses to connected devices.

Users have found that toggling the feature on and off can help in solving network-related issues to an extent.

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

• Open the Menu on your Vizio TV.
• Select Network.
• Select Manual Setup.
• Select DHCP and toggle it off and on.

Change DNS Servers

You can take the previous step even further by configuring a custom DNS server of your choice.

Domain Name System (DNS) helps in translating your domain names to IP addresses, and faster the DNS server faster will the time taken for fetching your results.

Although the default DNS in Vizio TVs works fine, you can further enhance its capabilities by linking other reputed DNS servers.

To change your DNS settings on your Vizio TV, follow the steps below:

• Open the Menu on your Vizio TV.
• Select Network.
• Select Manual Setup.
• Select DHCP and toggle it off.
• Select the Preferred DNS option and add the IP to the DNS of your choice (Eg: 208.67.222.222 for OpenDNS).
• Select the Alt DNS to any other DNS of your choice. GoogleDNS (8.8.8.8) is recommended for its stable and fast operations.

Limit Connected Devices

If there are too many devices connected to your WiFi, then it is entirely possible that your Vizio TV is not getting the bandwidth it requires for proper functioning.

If your WiFi router has hit its limit for connected devices, it might start kicking out connected devices to favor the addition of newer ones.

So disconnect your WiFi from devices that you are no longer using.

Turn off Guest Mode

Plenty of users have noticed significant speed and network performance drops when logged in with a guest profile.

Although not many are privy to the reason as to why, it is something to take caution of.

So if you are logged in via guest mode, it is best to swap profiles to your admin profile and check if the WiFi drops persist.

Turn Off Eco Mode

Eco mode is a helpful feature that helps in conserving power when your Vizio TV is not in use.

It basically turns off all your TV's background processes when the TV goes into standby mode.

These background processes even include networking, so basically your TV has to reconnect to your WiFi every time you turn on your TV from standby.

Although this is an innocent step taken in the right direction, it might not be ideal in your case where you need to stop the disconnections from happening.

So it is best to switch the eco mode back to the Quick Start mode, where the TV stays connected to the network for tasks such as invoking the assistant.

Also, in the real world, the difference in power consumption between the Eco mode and Quick Start mode is negligible at best, and the TV boots up faster in Quick Start mode.

To turn off Eco mode on your Vizio TV, follow the steps below:

• Open the Menu of your Vizio TV.
• Select Settings.
• Select System.
• Select Power Mode.
• Toggle the option from Eco Mode to Quick Start.

Turn Off CEC

Consumer Electronics Control (CEC) is a very popular standard that allows for your connected HDMI devices to be controlled with just your primary remote controller.

Although this can seem like a godsent feature at first glance, it is possible that your input devices might be sending commands that interfere with the WiFi connectivity.

It is best to toggle CEC off and check whether your disconnections are caused by it.

To toggle CEC off on your Vizio TV, follow the steps below:

• Open the Menu of your Vizio TV.
• Select Settings.
• Select System.
• Select CEC and toggle it off.

Update the Vizio TV

Firmware updates offer new life to Vizio TVs by providing patches to bugs that Vizio has worked on, as well as introducing the TV to new features.

So it is imperative to always stay on the latest available firmware patch, especially if you want to avoid issues such as the one at hand and numerous other ones like Vizio Chromecast not working.

Vizio TVs usually update automatically in the background when connected to an internet connection.

In order to invoke the update process manually, follow the steps below:

• Open the Menu of the Vizio TV.
• Select System.
• Select Check for Updates.

If the TV finds an update available, you can confirm the update when the dialog box pops up.

Power Cycle the Vizio TV and Internet Router

Power cycles are powerful troubleshooting processes that help in solving power delivery-related issues with almost all electronic devices, including Vizio TVs.

It helps in the even distribution of charges within the internal components of your Vizio TV so that it can perform to its maximum potential.

To perform a power cycle on your Vizio TV, follow the steps below:

• Unplug the Vizio TV from its power source.
• Let the Vizio TV sit idle in its powered-off state for about a minute.
• Plug the Vizio TV back into its power source.
• Let the Vizio TV sit idle in its powered-on state for about a minute.

While you're at it, it is also best to perform power cycles on your internet router as well.

Since your internet router is bound to be powered 24x7, the chances of power delivery issues are much higher leading to issues with relaying WiFi signals.

To power cycle your internet router, follow the steps below:

• Unplug the internet router from its power source.
• Let the internet router sit idle in its powered-off state for about a minute.
• Plug the internet router back into its power source.
• Let the internet router sit idle in its powered-on state for about a minute.

For the best results, it is best to perform multiple power cycles

Reset Vizio TV to Factory Defaults

Resetting the Vizio TV to factory defaults will wipe out all settings and personal data from your TV.

This also means that any software bug that might have been the cause of your frequent disconnections with your WiFi might get wiped out as well.

So it is best to reset your Vizio TV if nothing seems to work in helping get rid of your disconnections.

To perform a factory reset on your Vizio TV, follow the steps below:

1. Open the menu on the Vizio TV.

2. Select the System option.

3. Select the Reset and Admin option.

4. Select the Reset TV to Factory Defaults option.

5. If you have set a parental code, you will be prompted to enter it.

6. Select Ok to initiate the reset process.

Get an External Multimedia Streaming Device

If the above steps fail, then it can be a viable option to give up on it and invest in a third-party multimedia streaming device.

Smart TVs are severely underpowered for the price that you pay for them, and having a device such as a Roku or Fire TV stick can help in gauging the performance gap.

Since these devices have their own SoC and components, and connect via HDMI to your Vizio TV as an input source, they will work the same no matter how old your TV is.

Also, if you plan on upgrading in the future it is as simple as getting a newer external multimedia streaming device and plugging it into your Vizio TV.
