As we depend more on wireless technologies, such as remote working, remote learning, wireless headphones, smart home devices, and in-car entertainment systems, Bluetooth problems become increasingly prevalent in the United States. Due to frequent software updates and the upgrading of devices that generate competition between increasing quantities of devices trying to connect, Bluetooth may stop functioning sporadically.
This article provides a comprehensive overview of the most common sources and solutions for Bluetooth issues on your Windows PC, MAC, Android phone, iPhone, Wireless Headphones (including AirPods), and Vehicle Bluetooth systems. Most solutions will require you to perform a simple troubleshooting process, which will take less than 10 minutes, without replacing the device or contacting support.
Common Symptoms
Bluetooth is not working correctly means you might see one or more of them:
- You cannot use Bluetooth devices to pair
- Bluetooth device pairs but disconnects often
- There is no sound from Bluetooth headphones or speakers
- AirPods say they are connected, but there are no sounds
- The car’s Bluetooth connects, but calls and audio won’t connect
- The option for Bluetooth is either not there or grayed out
- Audio quality is poor, and you experience lag or drop outs when using Bluetooth.
The device you are trying to pair with does not show up as a discoverable device.
Possible Causes
When it comes to Bluetooth issues, it’s usually due to either software or signal problems, not hardware issues. Some of the most common causes of Bluetooth issues are:
- Temporary software glitches due to updates or long uptime.
- Out-Dated operating systems or Bluetooth drivers.
- Too many wireless devices nearby causing interference.
- Corrupted Bluetooth caches (on mobile devices).
- Incorrect pairing history of the device you’re trying to use.
- Low battery level on Bluetooth accessory device.
- Vehicle Infotainment System (MIS) limitations or outdated firmware.
Knowing what causes these types of issues will allow you to find the right solution much quicker!
Step-by-Step Troubleshooting Solutions
Follow these steps in order, starting with the simplest fixes.
Step 1: Toggle Bluetooth Off and On
- Deactivate Bluetooth on your device
- Wait for 10-15 seconds
- Activate Bluetooth once again
Why does it work?
It resets the Bluetooth radio and clears any minor connection issues.
What should you expect?
Bluetooth devices should now reconnect normally with minimal difficulty.
Step 2: Restart Both Devices
- Power down and then restart phone(s), computer(s) or tablet(s).
- Turn off Bluetooth devices (e.g., headset, keyboard).
- Turn the device back on.
Why This Works
Restarting will clear up any existing memory problems and re-load certain OS services.
Expected Result
A stable Bluetooth connection after you completes this step.
Step 3: Check Battery Levels
- Charge Completely! before trying to connect.
- Do not try connecting your Bluetooth accessory to a device that has absolutely no battery power (extremely low).
Why this Works
Having too little power may limit the distance you can connect to your Bluetooth device and also make it very hard for the Bluetooth device to find your device.
Expected Result
Fewer Connection Errors
Step 4: Forget and Re-Pair the Device
- Access your Bluetooth settings.
- Put your Bluetooth device in “pairing mode.”
- Locate your Bluetooth device in the list of devices.
- Press “Forget” or “Remove Device.”
- Power Cycle your Bluetooth device.
- Re-Pair Your Device.
Why this Works
When you forget your Bluetooth device, it removes the pairing information between your devices, so a new, clean pairing connection will be made.
Expected Result
Once the device is paired, you should no longer have an error when connecting the two devices.
Step 5: Fix Bluetooth Issues on Windows PCs
- Go to “Settings,” select “Bluetooth,” select “Devices” and make sure Bluetooth is turned on.
- Run the Bluetooth troubleshoot process.
- Check if Windows has any available updates for your Bluetooth driver. You need to do this via Device Manager.
Why this Works
The driver that controls the Bluetooth signal is also what controls the communication of your Bluetooth device on Windows.
Expected Result
Bluetooth devices will properly connect, and work as intended.
Step 6: Fix Bluetooth Issues on macOS
- Unplug and re-plug your Mac computer.
- Reset the Bluetooth function if needed.
- Remove and then reintroduce the Bluetooth devices you have already connected.
- Look for software updates for your Mac’s operating system that may help with Bluetooth connectivity.
Why Is This Helpful?
Apple typically releases operating system updates to improve the reliability of Bluetooth connections.
What Can You Expect?
Improved connectivity.
Step 7: Fix Bluetooth Issues on Android Devices
- Go to “Settings”
- Select “Apps”
- Select “Bluetooth”
- Clear the cache (do not clear the data)
- Restart your phone
When the cache is cleared, any corrupt temporary files related to Bluetooth will also be deleted.
Result: Your Bluetooth should work again normally.
Step 8: Fix Bluetooth Issues on iPhone and iPad
- Open the Settings app and select Bluetooth
- Turn off Bluetooth and then back on
- If necessary, perform a full network reset
- Lastly, make sure your device has the latest software
Why does it work?
Resetting Network Settings Resets Bluetooth/Wi-Fi Configuration Settings.
Expected results:
Consistent connectivity of Bluetooth Devices.
AirPods Connection Issues
Common problems:
- AirPods connect, but there’s no sound
- Frequent disconnects
- One AirPod is not working
Fixes
- Place AirPods in the case, close the lid for 30 seconds
- Reset AirPods using the case button
- Ensure AirPods are selected as audio output
- Update iOS or macOS
Expected result
Stable audio playback and proper pairing.
Car Bluetooth Issues
Typical issues include:
- Communication is established, but you don’t listen to audio.
- Call drops from the phone or is garbled.
- Bluetooth works sporadically.
Possible solutions:
- Unpair the device and re-pair it.
- Power recycle the vehicle’s AV system.
- Upgrade vehicle firmware if an upgrade is available.
- Limit the number of apps using Bluetooth in the background.
Assuming the changes have worked successfully, you should now have dependable hands-free calling and media playback through the vehicle’s audio system.
Multiple Bluetooth Devices Interfering
- Turn off unused Bluetooth devices
- Move away from Wi-Fi routers and microwaves
- Avoid pairing multiple audio devices simultaneously
Why it works
Bluetooth shares radio frequencies with other wireless devices.
Expected result
Reduced interference and stronger connections.
When to Seek Professional Help
If you experience one of the following situations you should contact your manufacturer’s technical support or take your device to an authorized repair technician:
- There is no option for Bluetooth on your device
- Bluetooth accessory detection does not work
- Bluetooth hardware is malfunctioning
- The problem persists even after reinstalling the operating system
Safety Tips: Do not disassemble your device if you were not requested to by the manufacturer. Opening devices may render warranty claims invalid and/or cause injury.
How To Prevent Future Bluetooth Issues:
- Keep your operating system current
- Don’t pair many devices
- Charge each accessory frequently
- Power down all devices once per week
- Update vehicle info-tainment firmware when updates are released.
These tips help particularly with employees working remotely or smart home customers.
Final Thoughts
When Bluetooth stops working, it can be very frustrating to not only have your work calls interrupted, but also any streaming or driving that may occur. Fortunately, most Bluetooth-related issues are simple and quick to solve, and will sometimes require only minor repairs, rather than replacing your entire device.
Adopting a methodical process for tackling issues will help users maximize savings while keeping them up-to-date on their technology (saving them both time and money) and decreasing their overall waste; therefore, Bluetooth will remain an essential and useful component within your everyday technological toolkit, whether you are at home or on the road.
FAQs
