Sonos Sub Not Connecting To Wi-Fi

The beauty of a Sonos Sub is that you can connect wirelessly to Wi-Fi, eliminating the need for wires. What does it mean when the Sonos sub is not connecting to the Wi-Fi?

If your Sonos sub is not connecting to Wi-Fi, there could be a network connection problem. Make sure the sub is connected to the correct network. Move the sub and router closer to each other. Restart the router. Remove the sub from the Sonos app and reinstall it.

Sonos subwoofers need a strong network connection. Remove anything that could be causing interference with the sub. If the sub continues to have connection issues, you need to reset the sub.

Sometimes resetting the sub will resolve any minor issues. Resetting the sub will remove the sub from the list of speakers within the Sonos app. Once the sub has been reset, you will have to add the sub back as though it were a new speaker.

The following steps will walk you through how to reset your Sonos sub.

Step 1: Unplug the sub from the wall outlet.

Step 2: Press and hold the Connect button.

Step 3: While still holding the Connect button, plug the sub back in.

Step 4: Keep pressing the Connect button until the LED indicator light flashes white.

Step 5: The LED indicator will flash green when the sub has been reset.

Step 6: Once the indicator light is green, you can add the sub back.

If the Sonos sub is trying to connect to a different Wi-Fi frequency than what the router is set at, the sub will not connect. Routers have a 2 GHz frequency and a 5 GHz frequency. Make sure the sub is connected to the one your router is set at.

Sonos Sub Not Connecting To Arc

Sonos subs come with Audio Return Channel that lets you route audio from the TV to the sub. What can you do when the Sonos sub is not connecting to Arc?

If the Sonos sub is not connecting to ARC, reboot the TV and the Sonos system. Unplug both the TV and the Sonos sub for at least 30 seconds. Rebooting both systems will refresh the software and will clear out any minor glitches. After 30 seconds, plug everything back in and try connecting again.

Sometimes the simplest of things is what is causing the problem. In this instance, is ARC turned on on the TV? Here is how you can check.

Step 1: After you have connected the sub via HDMI cable, go to your TVs Settings.

Step 2: Go to ‘Audio Output’.

Step 3: Scroll down and select ‘eARC mode’.

Step 4: Change ‘Dolby Digital Plus Out’ to ‘Dolby Digital Plus’.

Step 5: The sub should be connected to ARC.

Sonos Sub Not Connecting To Beam

You want to connect your sub to Beam so you have the ease of using Alexa to help you enjoy your speaker. But the sub is not connecting to Beam.

If the Sonos sub is not connecting to Beam, disconnect all external speakers. Insert the Beam’s AC power cord directly into the power port. Connect the HDMI cable to the HDMI ARC port. Make sure both cables are firmly inserted and are flush with the surface.

Not to be overlooked is the importance of connecting the HDMI cable to the correct port. If the Beam speaker is connected to the standard HDMI port, there will be no sound. If you do not have an HDMI ARC port, use the adapter cable that came with the Beam to connect the speaker.

Sonos Sub Not Connecting To Playbar

Are you not able to connect your Sonos sub to the Playbar? Here is why this is happening.

If the Sonos sub is not connecting to the Playbar, make sure the speakers are not receiving multiple signals. Use an Ethernet cable to connect the sub to the router. Turn on Wi-Fi on the sub so that the Playbar can connect wirelessly to the sub.

Adding multiple speakers that are trying to connect wireless will create what is called a Network Loop. The speakers will become confused by the multiple connections and will then not connect at all.

By connecting the Playbar to the router, you can turn on the Wi-Fi signal so that the sub can connect wirelessly to the Playbar. The Playbar becomes the connection piece between the sub and the router. Only one line of network communication is created.

Sonos Sub Not Connecting To TV

Your TV is on playing a show but there is no sound coming from the Sub. Why is the Sonos sub not connecting to the TV?

If the Sonos sub is not connecting to the TV, make sure the sub is connected to the correct HDMI port on the TV. The sub should be connected to HDMI ARC. If no signal is detected from the TV, make sure the sub is connected to the TV’s digital optical port.

Not connecting to the correct port will create a host of problems and stress that can easily be avoided. It’s just as equally important to make sure the sub and TV are connected to the same network.

When connecting the HDMI cable, make sure the TV’s HDMI CEC setting is turned on. For Samsung – Anynet. For LG – Simplink. For Sony – Bravia Sync.

Once you have confirmed the TV is ready to connect to the sob, open the Sonos app on your mobile device. Go to ‘Settings’ > ‘System’ > find the room your sub is connected to > select ‘TV Set Up’ and then follow the instructions.

If the sub is not listed among the connected devices, the app may need to be refreshed. Uninstall the app and then reinstall it. You will have to go through the initial setup process again to connect the sub to the app but it would be cleared of any glitches now.
