Title: TP-LINK UB500 Plus | Long Range Bluetooth USB Adapter at 2026
Post by: Kiriakos GR on June 24, 2026, 01:35:23 PM

TP-LINK UB500 Plus
Long Range Bluetooth USB Adapter.

This article starts here as information tip for the year 2026.
According to AI:
Specifically, the device relies on the Realtek RTL8761B silicon architecture.
TP-Link packages this specific integrated circuit inside the adapter casing and overlays it with their custom-signed firmware configurations.

Why it matters for Windows 7: Unlike newer hardware variants (such as the Asus BT540), Realtek authored highly stable, dedicated legacy driver configurations for the RTL8761B platform.

I have added it at my wish list.

When I will have spare cash and no other needs, I will order it (local stock).

Operating System Support: Unlike V2.60, both V1 and V1.6 retain legacy support, functioning across Windows 11, 10, 8.1, and 7.

V2.60 TP-LINK messed up here OS compatibility.
This hardware revision works only at  W10 / W11

And so it is required significant caution at checking first actual in stock revision, before ordering.
