Why does Bluetooth keep disconnecting

[KidKid]

Why does Bluetooth keep disconnecting on my PC? My BT mouse disconnects a few times every week, but when I connected BT speakers, they disconnect multiple times a day. Is my motherboard's BT a piece of trash, or is this software? Using Bluetooth 5.0. Thanks!

• Faulty BT module
• no antenna connected
• driver fault

Maybe for all (I don't remember seeing an antenna), but I do use an HP Pavilion prebuilt, and you know how they cheap out sometimes!

Sorry, I use Bluetooth 5.0, not 4.0. I updated the post.

1. Use the motherboard control app and update to the latest available BIOS version.
2. Download the latest Bluetooth driver from the MB manufacturer's website. Your model->Support->Downloads

It's like Windows. I have experience with Bluetooth on Windows. It's not great. Microsoft promised they would fix it with Windows 11 and still have not. It's so bad I gave up on using Bluetooth on my Windows machine. I just hook the headset up via a wire.

The BT module in your machine also affects the quality and connection. The one used in my Surface PRO6 works like a champ.

My friend said the same about his Surface. Not sure what WiFi cards they are using in those. I know with every machine I have used Bluetooth on. Windows 7 worked the best with a $6.99 USB Bluetooth adapter from Amazon, 85 to 90% of the time it worked good. Windows 10 was much less. Windows 11 sucked just as bad. Besides connection issues, windows has a habit of switching to headset mode and ruining sound quality. Sure it could be the M.2 WiFi card on my motherboard or even the antennas placement. As it stands I gave up. I run my HD4.50's wired with Windows and Bluetooth with my Mac.

I get you, for my desktop, I use a bt dongle. Though it runs well for a for a good while it will then magically decide it doesn't want to connect...  i know it's not the dongle.

I run w10.

I see. Maybe it's Windows 11's problem then.

It disconnected again. I checked Event Viewer and got this -

Windows cannot store Bluetooth authentication codes (link keys) on the local adapter. Bluetooth keyboards might not work in the system BIOS during startup.
