I would like to offer the assistance of our award-winning technical support team with this issue. Please visit support.VIZIO.com and click on ‘Contact Us’. We’ve got agents ready to chat, text message, or speak with you on the phone.

We appreciate you taking the time to review our product. We are constantly working to deliver exceptional value, endless entertainment options and amazing customer experience. We’ll continue to use feedback like yours to improve our TVs and the user experience in the future. Usually this issue is caused by incorrect router settings or Ghz of the network as this TV model is only able to connect to a 2.4G network. Thanks!

Hello Peggy382009, as televisions continue to have larger screens with thinner profiles and sleeker bezels, there is less room for large speakers. To help get the best audio quality out of your VIZIO televisions speakers, we’ve included settings like DTS Studio Sound to provide the highest performance possible, while maintaining the thin, sleek, bezel-less profile of your television. If you’d like any help adjusting your audio settings feel free to contact VIZIO support at 844-254-8087.  For top of the line audio performance, you may also look into purchasing a VIZIO Sound Bar, there are several models available with wireless subwoofers for enhanced bass, rear speakers for true surround sound, and our new line of Atmos Sound Bars.
