Step 2: Turn On Your Soundbar and Enable WiFi Setup Mode
- Plug in and power on your Vizio soundbar.
- Press and hold the Bluetooth and Volume Down buttons on the soundbar simultaneously for 5-10 seconds.
- The LED indicators will flash, indicating WiFi setup mode is activated.
Note: On certain models, you may need to hold the Input and Bluetooth buttons instead. Consult your user manual if unsure.
Step 3: Open the SmartCast App and Add Your Soundbar
- Launch the SmartCast app on your phone.
- Tap on the Devices icon (top-right corner).
- Select Add New Device or Set Up a New Device.
- Wait while the app detects your soundbar in WiFi setup mode.
Step 4: Connect to Your Home WiFi Network
- Once your soundbar appears, tap on it.

- Tap Connect.
The app will finalize the process and confirm the soundbar is now online. You can now access SmartCast controls, firmware updates, and voice assistant settings.
What to Do If the Soundbar Fails to Connect to WiFi
WiFi setup doesn’t always go smoothly. If you’re having trouble, try the following fixes.
1. Restart Your Soundbar and Router
- Power off both devices.
- Unplug them for 60 seconds.
- Plug them back in and retry the connection process.
2. Ensure 2.4GHz Compatibility
Most Vizio soundbars connect only to 2.4GHz WiFi networks. Ensure your router is broadcasting this band. If you’re using a dual-band router, make sure you’re not trying to connect to the 5GHz network.
3. Perform a Factory Reset on the Soundbar
To reset your soundbar:
- Press and hold the Bluetooth and Volume Up buttons together for about 10 seconds.
- LED indicators will flash, and the soundbar will reboot to factory defaults.
Then, restart the setup process through the SmartCast app.
4. Update the SmartCast App
Using an outdated version of the SmartCast app can cause connectivity issues. Check for updates in the App Store or Google Play and install the latest version.
5. Reduce Distance and Remove Obstacles
Place your soundbar closer to the router and remove any physical obstructions that may block signal strength. Alternatively, use a WiFi range extender for better coverage.
Enhancing the WiFi Experience with Your Vizio Soundbar
Once you’re connected, here’s how to get the most out of your WiFi-enabled soundbar.
Enable Automatic Firmware Updates
Keep your soundbar running smoothly:
- Open the SmartCast app.

Common Questions (FAQs)
Do All Vizio Soundbars Support WiFi?
Not all models do. Only SmartCast-enabled soundbars have built-in WiFi support. To confirm, check your user manual or visit Vizio’s official support page.
Can I Use My Soundbar Without WiFi?
Yes. You can use HDMI ARC, optical cable, or Bluetooth for audio input. However, without WiFi, you lose access to streaming features, firmware updates, and voice assistant controls.
How Can I Tell If My Soundbar is Connected to WiFi?
- Open the SmartCast app.
- Select your soundbar.
- Tap on Settings > Network to view the connection status.
Can I Connect My Soundbar to Hotel or Public WiFi?
Generally, no. Most public WiFi networks require a browser-based login, which soundbars do not support. If needed, consider using a travel router to create a private WiFi network.
Alternative Connectivity Options
If WiFi is not available or feasible, you can still enjoy excellent audio using these alternatives:
Ethernet Connection (If Supported)
Some premium Vizio soundbars include an Ethernet port. If yours does:
- Connect an Ethernet cable from the router to the soundbar.
- This provides a more stable connection than WiFi.
Bluetooth Pairing
Bluetooth setup is quick and ideal for mobile devices:
- Press the Bluetooth button on your soundbar.
- Open your phone’s Bluetooth settings.
- Select your Vizio soundbar from the available devices.
Note: Bluetooth does not support SmartCast features or firmware updates.
HDMI ARC and Optical Input
These wired connections deliver superior audio quality:
- HDMI ARC allows for TV audio playback and remote control via one cable.
- Optical Cable provides digital sound and broad compatibility with TVs.
Tips to Maintain a Reliable WiFi Connection
Even after a successful setup, maintaining a strong connection is important. Here’s how:
1. Use a Dedicated 2.4GHz Band
Separate your soundbar’s network from high-traffic 5GHz devices to reduce interference.
2. Avoid Network Congestion
Limit simultaneous video streaming, gaming, or downloads while using your soundbar over WiFi.
3. Regularly Restart Your Router
A simple router reboot every few weeks can resolve latent connection issues and improve performance.
4. Keep Devices Updated
Always update your SmartCast app and firmware to the latest versions.
