“But James, we can’t connect Vizio Soundbar to SmartCast app!” I’ve got you covered, guys. Let’s learn some basic troubleshooting steps to help fix some of the most common connection problems people have been experiencing. 

Vizio Soundbar Not Connecting to SmartCast App

If your Vizio device is not connecting to the SmartCast app, uninstall the app on your mobile phone and reinstall it. You can attempt to reconnect the device to the soundbar again. Similarly, you can also disconnect from the network and try reconnecting. Most of the time, people forget to switch their phone from data to wifi, which is why the soundbar fails to connect to the SmartCast app. 

You can also try resetting your Vizio soundbar to factory settings. Restoring the device to its default settings can sometimes help solve connectivity issues. Consequently, a factory reset will also erase all your custom settings and preferences from the device. 

Hold down the Bluetooth and Volume Down button simultaneously for five seconds on your soundbar to attempt a factory reset. The 12 LEDs on your device will flash three times. Once that’s finished, the factory reset is complete. You can try reconnecting to the SmartCast app now.

Why Is My Soundbar Not Connecting to Wifi?

If your soundbar is experiencing wifi connectivity problems, ensure the device turns the Link option on. You can access this via the remote control. 

If that doesn’t solve your problem, you can try resetting the soundbar to reset services that are not functioning correctly. For this, you need to unplug your device and pull out all the cables. Wait for at least a minute, then plug the device back in.

However, if this does not cause the device to enter pairing mode, you might have a firmware issue. Download the latest Vizio firmware onto your computer and transfer it to a USB flash drive. You can use that to update your soundbar’s firmware manually.

Another problem that people face due to connectivity issue is that their sound bar keeps cutting out. Refer to this article for some easy fixes.

How to Connect Vizio Soundbar to Wifi Without Remote?

A remote is the most convenient way to use your Vizio device, but sometimes, remotes get lost or stop working. If you ever face a similar issue, you can just connect to the wifi without it! You just need to do look for the Source button on your soundbar. In most models, it’ll be located on the back of the device. 

Press this button, and your Vizio soundbar will enter the wifi pairing mode. From here, you can follow the initial steps to connect to the SmartCast app on your phone and enjoy all wifi benefits. However, this can be a hassle for some people, so I recommend quickly replacing your lost or broken remote.

If you have a Vizio TV, you can also use its companion USB keyboard to set up a universal remote for all Vizio devices. This lets you access the soundbar settings to pair with the SmartCast app on your phone. You can then use your phone to download remote apps and tinker with the soundbar’s settings. Again, replacing your lost remote is your best bet for a smooth and hassle-free experience. You can read more about Vizio’s universal remote control and remote-control codes here.
