Question Realtek Gaming 2.5Gbe - Bluetooth not finding any devices

[Duinan]

My bluetooth radio appears to be on, driver updated, and device removed and added back again. It refuses to recognize any bluetooth device that is in paring mode (headset, mouse, earbuds). I set it to be searchable by other systems, and don't see it on my iphone. (All the other devices show up there, as well as a dell laptop).

I built the system a couple of years ago, but to be honest I don't know that I've ever used bluetooth on this rig. Never had any problems with the ethernet connection. I've updated, uninstalled, reinstalled, rebooted, disabled, etc.

I don't mind buying a USB adapter (just want the bluetooth for some headphones) but I'm concerned that it will conflict with the onboard radio.

System info:
Windows 24H2
Adapter: Realtek Gaming 2.5GbE Family Controller
MoBo: Gigabyte B650 GAMING X AX
Belarc shows the following:

↓ Bluetooth Device (Personal Area Network)
	Status:	Cable unplugged
Link-local IPv6 Address:	xxxxxxxxx
	Dhcp Server:	none responded
	Physical Address:	xxxxxxxxx
	Connection Speed:	3 Mbps

Device Manager has the following entries:
Bluetooth
- Bluetooth Device (RFCOMM Protocol TDI)
- Generic Bluetooth Adapter
- Microsoft Bluetooth Enumerator
- Microsoft Bluetooth LE Enumerator
Network Adapters
- Bluetooth Device (Personal Area Network)
- Realtek Gaming 2.5 GbE Family Controller

Also, under Other Devices
- Network Controller (Warning showing now drivers for this device are installed)
No driver available for this, it was installed 1/30/25 so not something part of the initial build. The event log shows the message "Device PCI\VEN_10EC&DEV_C852&SUBSYS_C85210EC&REV_01\00E04CFFFEC8520100 was configured."
Not sure what other information may be of use.

Thanks in advance for any help!

Do you have the antenna attached to the motherboard? If not, do so and try again. That is needed for the adapter to work properly.

I thought that was just for WiFi? I went ahead and attached it, rebooted, still no luck.

No. Not just for Wi-Fi. BT, too.

What revision is your motherboard?

Did you install Realtek 8852 WLAN + BT driver?
