Solution 1: Try to Power Cycle if Your Vizio SmartCast is Not Working

Sometimes, your Vizio SmartCast not working is because of a very small software glitch in its system. Well, the good news is that this type of error is among the easiest to be addressed.

Solution 2. Refresh the Network’s DHCP Settings

Sometimes, the ‘Vizio SmartCast not working’ issue can relate to a faulty DHCP setting on the network connected to the Vizio SmartCast.

You should rectify the DHCP settings to address the issue if that is the case. The purpose of DHCP settings is to assign an IP address to the clients (devices) on the network. DHCP stands for the term Dynamic Host Configuration Protocol.

As you can realize, the term describes what this protocol does on the network.

In general, any home network might have more than one device. Your laptop, smartphone, a tab or two, etc., will be connected to the home network.

That is in addition to the Vizio SmartCast TV. Each of those devices will be given unique IP addresses by the DCHP protocol. In other words, the DCHP protocol ensures that no two devices have the same IP address on a network.

As a result, there will not be any conflicts when devices communicate with the router.

As long as the DHCP settings are properly configured, the network connection should run very smoothly. However, there are times when the DCHP protocol is improperly configured due to some reason or another.

If that is the case with you, by any chance, there can be conflicts in the network. This means there can be instances when the same IP address is assigned to two IP addresses. As a result, your Vizio SmartCast can become unresponsive.

In other words, your Vizio SmartCast not working due to a misconfiguration in your DHCP configuration.

So, the solution to address this situation is reenabling the DCHP settings. Once the DHCP settings are refreshed, the devices will be assigned IP addresses properly. As a result, all the devices will communicate with the router without conflicts.

Follow the Steps to Change the DCHP Settings of the Network.

Also, the steps can vary slightly based on the router.

  • Turn your Vizio SmartCast TV off.
  • Then, launch a web browser on your computer (which is already connected to the same network).
  • Now, you can access the router by entering its URL on the browser’s address bar. Once the router page is loaded, you should enter the username and password to access the settings.
  • Once you have gained access to your router, just enter the “Settings” page.
  • You can now go to the DCHP settings section of the router and click on it. Please note that the path can vary depending on the router type. For instance, it can be in the “Advanced,” “Network,” “Setup,” etc.
  • You can then enable the DCHP option. If the option is already enabled on the settings, you should disable it first. Then, wait for a couple of seconds and enable it once again.
Refresh the network's DHCP settings
  • Now, you can exit the router page after saving the settings.
  • You can now turn on the TV and check if the problem is gone.

This solution would have fixed the ‘Vizio SmartCast not working’ error if the case was related to DHCP settings. However, if the problem persists, you should take the extra step to manually edit the router settings.

In this case, you should edit the settings so the router will use Google DNS. Then, check if the Vizio SmartCast is working as expected.

Solution 3. Try the Same Device with a Different Network

If none of the above options have worked for you, try this method. In this case, we assume everything is fine with the TV set, but something’s wrong with your network. Also, some ISPs can have some restrictions on their web traffic.

They use different techniques to take control of the network to assure safety. So, if there is an added layer of security in your network, that can cause this Vizio SmartCast not working issue.

In certain cases, ISPs directly prevent users from accessing various services. If they block a service required by your Vizio SmartCast TV, that can cause problems. So, to address this issue, you should simply connect the same device to a different data network.

That would be the best move if you could connect the device to a network under a different ISP. You can simply activate your smartphone’s hotspot if you don’t have a different Wi-Fi network at home.

So, once again, the key is to connect the device to a network from a different ISP.

  • To do that, you should first connect the TV to a different network. Use a hotspot created on your mobile device if there is no other network.

  • You can now check if your Vizio SmartCast TV is working as expected. If Vizio SmartCast is not working, the issue might not be on the network. In that case, you will have to move to the next step (which is the last resort).
