The primary hurdle for the Ralink RT3290 on Windows 11 is that MediaTek (which acquired Ralink) has largely ceased official driver updates for this specific chipset. Windows 11 requires modern driver architectures and security standards that the RT3290 was not originally designed to meet. Consequently, users often encounter "Yellow Bang" errors in Device Manager or find that Bluetooth simply disappears after an OS update. Solutions and Workarounds
Enable Bluetooth in the BIOS and ensure it is not disabled. Ralink Rt3290 Bluetooth Driver Windows 11
The Ralink RT3290 is a legacy combo card (Wi-Fi and Bluetooth) commonly found in older laptops like the HP Pavilion 15 The primary hurdle for the Ralink RT3290 on
The Ralink RT3290 is a combined Wi-Fi + Bluetooth 4.0 chipset from circa 2012–2013. for this device. The last official drivers were for Windows 8.1 (64-bit). However, the Windows 8.1 driver can work on Windows 11 with a manual, forced installation procedure. Without this, Bluetooth will likely show as “Unknown USB Device” or fail to start (Code 10/Code 43). Solutions and Workarounds Enable Bluetooth in the BIOS
If this didn’t work (which is common for this specific card on Windows 11), proceed to Method 2.
