Solution 3: Enable DHCP on your Vizio TV

Dynamic Host Configuration Protocol or DHCP for short is responsible for assigning IP addresses to each device connected to the network.

Your Vizio TV must have a unique IP address so that it has no problems with its internet connection.

Select Manual Setup
Select DHCP

Solution 4: change your Wi-Fi password

If many devices are connected to the wireless router, this could cause connectivity problems.

This will ensure that only the TV is connected to the router while other devices will not be able to connect.

To change your router’s wifi password, you need to consult your router’s manual on the exact procedure as different router models have different ways to do it.

While you are changing the password, you should also consider changing the router security to WPA-PSK [TKIP] encryption as this is what works best with your Vizio TV.

Once the password is changed, you need to forget the wireless Internet connection from the TV, and then reconnect to it using the new password.

Solution 5: Try using an ethernet cable

If your TV model has an available ethernet port, you should try using a wired connection using an ethernet cable to connect to the router.

If this solves the problem, the TV wireless adapter may not work. You will need to have it checked at a service center.

Solution 6: Perform a factory reset on the TV

As a last resort, you should consider doing a factory reset. This will restore the TV to factory settings. Note that if you have downloaded apps to your TV, you will need to download them again.

Click the Menu button on the remote control.
Select System.
Go to Reset and Admin.
To perform a factory reset, select Reset TV to factory settings.
Once the TV is running with the factory default settings, it takes you to the original setup screen. Perform the initial setup, then connect the TV to the wireless network and check if the problem persists.

Solution 7: Contact Vizio customer support

Final thoughts

It is generally quite easy to troubleshoot Wi-Fi connection problems on your Vizio TV. Most of the time a simple reboot will do the trick. Here are some tips to ensure you have the best viewing experience on your smart TV.

Make sure you are subscribed to a high-speed internet plan. The more bandwidth you subscribe to, the better it is for streaming shows.

Make sure the TV can receive a strong wifi signal from the router. If the signal strength it is receiving is low, you should consider investing in a wifi extender.

Make sure you update your TV to the latest software version.
