Smart FAQs

1. Does the UB400 work with Windows 11?

Yes. The UB400 is compatible with Windows 11 and Windows 10 with plug & play support; older Windows versions may require drivers included on the CD or downloadable from TP‑Link’s website.

2. Can I use this adapter with macOS or Linux?

UB400 is primarily designed for Windows. macOS and Linux support may be limited or require additional drivers; check TP‑Link resources for community or driver options before purchase.

3. How many devices can I connect at once?

Multiple devices (keyboards, mice, headsets) can be paired, but simultaneous active connections depend on device types and system resources. For best performance, prioritize audio and input devices as needed.

4. What is the effective Bluetooth range?

Typical indoor range is up to 10 meters (line of sight). Actual range can vary with walls, interference and device antennas.

5. Is there any noticeable audio lag for gaming or calls?

Bluetooth 4.0 offers low latency for everyday use. For competitive gaming, wired or lower‑latency Bluetooth codecs may be preferable. Most headsets and controllers perform well for casual gaming and calls.

6. How do I install it?

Plug the adapter into a USB port. Windows 10/11 should detect and install drivers automatically. For older Windows versions, use the included CD or download drivers from TP‑Link’s support site.
