Sony Usb Wireless Lan Adapter Uwa-br100 Driver Windows 10

Sony does not offer an official Windows 10 driver for the Sony UWA-BR100

Identify the adapter and chipset:

The Workaround: Chipset Identification Despite the lack of official branding, the hardware inside the UWA-BR100 is standard. The solution for Windows 10 users lies in bypassing the Sony-specific branding and installing a generic driver compatible with the internal chipset. The UWA-BR100 is widely recognized by the tech community as being built on the Realtek RTL8191SU platform. Therefore, the installation process is not about finding a "Sony" driver, but rather finding the correct "Realtek" driver that Windows 10 can digest. This requires a manual intervention known as "forcing" the driver or updating it via the Device Manager. sony usb wireless lan adapter uwa-br100 driver windows 10

That said, there are experimental workarounds for advanced users. The most reliable method involves disabling Driver Signature Enforcement (via the Advanced Boot Options menu) and then forcing a manual installation of the 64-bit Ralink RT2870 driver from a trusted source (e.g., the official MediaTek legacy driver archive). Alternatively, some users have successfully extracted the driver from the Sony DWA-171 adapter package, which shares a similar chipset family. However, these solutions are temporary (driver signature enforcement re-enables after a reboot) or require disabling critical security protections, rendering the machine vulnerable to rootkits. A more practical, albeit defeatist, solution is to simply replace the $5 legacy dongle with a modern, $15 USB Wi-Fi adapter that natively supports Windows 10 (e.g., from TP-Link, ASUS, or Edimax).

This last point is your golden ticket. Sony did not manufacture the internal chips; they rebranded a reference design from Ralink (now owned by MediaTek). Therefore, the Sony-branded drivers are just custom-skinned versions of generic Ralink drivers.
