Are you tired of your computer's built-in Bluetooth capabilities being outdated or unreliable? Do you want to easily connect your devices, such as headphones, speakers, or smartphones, to your computer without the hassle of cables? Look no further than the TP-Link UB400, a compact and affordable Bluetooth 4.0 USB adapter.

If you have previously used a different Bluetooth dongle (like a CSR or Cambridge Silicon Radio device), old drivers can conflict with the UB400. Use a driver cleaner tool or manually remove old Bluetooth drivers in Device Manager before installing the UB400.

Note: If there is no driver listed for Windows 10/11 on the site, it confirms that the device relies on the built-in Windows Bluetooth stack.
