The first time you connect a wireless device
Wireless earbuds, keyboards, mice, and speakers all rely on the same basic Bluetooth pairing process the first time they connect to a new computer. Once paired, the device typically reconnects automatically the next time both it and the computer have Bluetooth turned on, so this setup only needs to happen once per device.
If the device is not showing up in the list
A device that will not appear almost always comes down to one of two things: it is not actually in pairing mode, or its Bluetooth is not turned on at all. Most devices need their pairing button held down for a few seconds -- a quick press is often not enough -- so it is worth confirming that specifically before assuming something is broken.
Frequently Asked Questions
What if the device does not show up in the list?
Double-check that Bluetooth is turned on for the device and that it is actually in pairing mode -- usually entered by holding its pairing button down for a few seconds -- and confirm Bluetooth is on for your computer as well, then search again.
How do I remove a device I already connected?
On the same "Bluetooth & devices" screen, click the connected device and choose "Remove device" to delete the connection.
