Vizio TV Not Working On Ethernet Cable? Try These Fixes!!

Do you experience problems using the ethernet connection on your Vizio TV for accessing the internet? Is it showing the wired connection disconnected, not recognizing it, or not allowing you to access the internet with the wired connection?

My other Vizio TV did have this problem as well, that I encountered myself, mostly, I am using the ethernet connection for my TV and gaming consoles, both of which require a steady connection. Wired connections are always more reliable than wireless connections because ethernet provides better stability.

First, everything worked just fine. I simply plugged one end of the Ethernet cable into my router and the other end into the Ethernet port on the back of my Vizio TV. However, after a while, it displayed no internet connection, and the “wired connection disconnected” message appeared on the network screen.

When I tried to reconnect it, it failed to recognize the connection, whereas when I connected my laptop via an ethernet cable it worked fine.

I know it is a strange issue and there is something glitching between the TV and router, so I searched through various forums, contacted the support, and spoke with other Vizio TV users who have faced this issue in the past.

It turns out that it is quite common for the Vizio TV to not recognize the internet connection over the wired connection (ethernet). 

In this guide, I will tell you how to get the Vizio TV ethernet connection fixed as well as some other things related to it.

So before you jump straight into troubleshooting, make sure the network connection between your TV and router is set up correctly and in the correct manner.

Vizio Smart TV Ethernet Connection Not Working

Ethernet not working Vizio TV troubleshooting

Numerous Vizio TV users have reported that even after following the proper connection process, they are unable to access the internet as the ethernet connection stops working and the TV shows that the connection is disconnected.

First of all, it’s not related to any major problem, and in the majority of cases, it can be fixed with only a few simple steps.

According to official Vizio TV support and several other Vizio TV users, the ethernet connection stops working when the router does not have internet access, the cable connection is not good, or when the TV has temporarily glitched. You may need to check your router’s internet connection, reconnect cables, and power cycle your TV to fix it.

Most of the time, performing only the above steps will solve the issue, but there may be other underlying issue such as DHCP issues, router configurations, incompatible ethernet cables, etc. 

You don’t have to worry, as I have considered all possible causes of the internet issue over the wired connection on your Vizio TV over ethernet cable and if you follow the steps carefully your Vizio TV internet will begin working perfectly fine.

Initial troubleshooting

Initial Checks
Initial Checks

Ensure the router has internet access.

It is important to check the internet network when the Vizio TV is showing disconnection errors with a cabled connection.

Vizio TVs often have problems if their software or firmware has not been updated. This usually occurs when your TV’s firmware and software are not current.

Make sure the ethernet cable port on your TV is not damaged. In the event that the port is damaged, the connectivity may be negatively affected. It is, therefore, necessary to have the TV technician replace the port on your TV.

Alternatively, if you cannot access the internet on another device either, you should call the internet service provider for help.

Inspect ethernet cable.

When ethernet cables are used for long periods of time, they tend to get torn out and their end ports become loose, which is why you should ensure that the ethernet cable is a high speed and in good condition.

Main Troubleshooting 

Perform Power Cycle 

Power Cycle

To begin the main troubleshooting process, perform a power cycle.

In spite of what you may think, the factory reset and power cycle work differently, and sometimes a factory reset doesn’t fix the problem, whereas a power cycle might work.

The same thing happened to me when I tried to do a factory reset, but still, the issue persisted. Support advised that I do a power cycle, and I was happy to see that it fixed the issue instantly.

Here’s how to do a proper power cycle:

The wired connection will work after you power cycle the TV (unplug the TV, hold down the power button for ten seconds, plug it back in, and turn it back on).

Configure DHCP 

Configure Router

In order for the internet router and TV to function properly, the DHCP settings must be configured correctly.

Therefore, the DHCP settings need to be toggled when there is a problem with the connection. Here are the instructions that you can follow to toggle DHCP settings.

  • To begin, press the menu button on your Vizio
  • Select the network option from the menu, and then click on the manual setup button
  • Tap twice or three times on DHCP during the manual setup

Assign Static IP 

Several Vizio TV users have verified this solution on social sites and support forums, I have not tried this as my issue was fixed by performing a power cycle and tweaking the DHCP. 

However, if none of the above steps work for you, you will need to assign a static IP to your router and your internet service provider will do that for you.

Factory Reset your Vizio TV

Factory Reset

You should perform a factory reset on your Vizio TV and router if none of the above work.

What is the point of performing a factory reset on both the TV and router?

Due to half-updates, outdated firmware, and the like, we have minor glitches as well as wired network connection problems.

Here’s what the official Vizio Twitter Support respond to the same concern where a Vizio TV user complaint about the “Network Disconnected” issue over ethernet cable.

As soon as you perform a factory reset, both the router and TV will be set to default and will automatically install the latest stable updates. 

Once this has been completed, you can connect your TV to your network via an Ethernet cable.

Switch Ethernet Port and Cable

If you have not made any progress after performing all the above steps, you can either switch the ethernet cable to a different port, or you can purchase a new ethernet cable that has high speed.

Furthermore, if none of the above steps have worked, you can also contact the official Vizio support so that they can investigate the problem. 

As, If none of the above steps have worked, then hardware problems can also be considered.

Wrapping Up

There is no doubt that an Ethernet connection is better than a wireless connection, but when it itself starts acting up and our TV doesn’t recognize the connection, this can become quite annoying.

Fortunately, the issue isn’t major as it can be solved by taking a couple of steps in your home.

It is my hope that you will be able to resolve any issue with your Vizio TV over Ethernet cable with the help of the above guide.

Please feel free to leave a comment below if you encounter any challenges while following the above steps or if you need further assistance.


Do all Vizio TVs have ethernet ports?

Most Vizio TVs have an Ethernet port on their back panel, which can be used to access the internet via wired cable rather than via inbuilt wifi.

What if my tv doesn’t have an ethernet port?

A USB ethernet adaptor is quite cheap, but it is really useful if your Vizio TV doesn’t have an Ethernet port.

I myself have it, and I can connect it to my laptops and TV whenever I want to use the internet over wired connections.
