Bluetooth Not Working on Windows 11? Fix Headphones, Mice, and Speakers That Won’t Connect

New wireless earbuds, a Bluetooth mouse, or a speaker for the kitchen are some of the most popular gifts this time of year. And one of the most common calls I get from folks around Strasburg, Byers, and Bennett goes like this: “It worked yesterday, and now my computer won’t see it.” Bluetooth on Windows 11 is usually reliable, but when it acts up it’s frustrating, because there’s no cable to wiggle.

The good news is that most Bluetooth problems are fixed in a few minutes without buying anything. Start at the top of this list and work your way down.

Quick Fixes First

1. Turn Bluetooth off and back on. Click the Wi-Fi, volume, and battery icons in the bottom-right corner to open Quick Settings, then click the Bluetooth tile off, wait ten seconds, and click it back on. You can also do this in Settings, then Bluetooth & devices.
2. Make sure Airplane mode is off. Airplane mode turns off Bluetooth along with Wi-Fi. It’s easy to bump on by accident, especially on laptops with a function key for it.
3. Charge the device and restart the computer. Low batteries cause a lot of dropouts, and a full restart (not just closing the lid) clears up more Bluetooth glitches than anything else.
4. Put the device in pairing mode. Being turned on isn’t the same as being ready to pair. Most earbuds pair by holding a button on the case; most mice have a small button underneath. Check the little instruction sheet for your model, and look for a blinking light.
5. Remove it and pair it again. In Settings, then Bluetooth & devices, click the three dots next to the device and choose Remove device. Then click Add device, choose Bluetooth, and pick it from the list. This fixes the “paired but not connected” problem most of the time.

One more thing: Bluetooth gadgets can usually only connect to one device at a time. If your earbuds are still connected to your phone, the computer may not be able to grab them. Turn Bluetooth off on the phone for a minute and try again.

The Bluetooth Button Is Missing Completely

If there’s no Bluetooth tile in Quick Settings and no Bluetooth switch in Settings, Windows can’t see the Bluetooth hardware at all. Some desktop computers simply don’t have Bluetooth built in. In that case a small USB Bluetooth adapter is an inexpensive fix. On a laptop, try a full shutdown, then check Device Manager (right-click the Start button and choose Device Manager) for a Bluetooth section. If it’s missing or shows a yellow warning, the driver steps below are your next stop.

Still Won’t Connect? Try These

1. Run the Bluetooth troubleshooter. Search the Start menu for troubleshoot, open the troubleshooting settings, and run the Bluetooth option (on newer versions of Windows 11 it opens in the Get Help app). It checks the common settings automatically.
2. Install Windows updates. Bluetooth driver fixes often arrive through Windows Update, including the optional updates section. If updates themselves are giving you trouble, my Windows Update fix checklist can help.
3. Update or reinstall the Bluetooth driver. In Device Manager, expand Bluetooth, right-click your Bluetooth adapter (often named Intel, Realtek, MediaTek, or Qualcomm), and choose Update driver. If that doesn’t help, choose Uninstall device and restart; Windows reinstalls it on the way back up. Your computer maker’s support website is the best place for the newest driver, not a random “driver updater” download.
4. Restart the Bluetooth Support Service. Press Windows key + R, type services.msc, and press Enter. Find Bluetooth Support Service, right-click it, and choose Restart.
5. Stop Windows from turning it off to save power. In Device Manager, double-click your Bluetooth adapter. If there’s a Power Management tab, uncheck the box that lets the computer turn off the device to save power. This helps when a mouse or headset keeps disconnecting after a few minutes.
6. Watch for interference. USB 3 ports, USB hubs, and some wireless gear can interfere with Bluetooth. If a desktop has its adapter on the back, a short USB extension cable to bring it up onto the desk can make a big difference.

Connected, But No Sound?

If your headphones say connected but the sound still comes out of the computer speakers, click the volume icon in the corner, then the arrow next to the volume slider, and pick your headphones as the output. For more sound troubleshooting, see my guide on fixing no sound after a Windows update.

Setting Up a New Computer This Season?

If your Bluetooth gear is going with a brand-new PC, pair it after Windows finishes its first round of updates. My new Windows 11 computer checklist walks through what to do first.
