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

Legacy drivers designed for Windows 7 or Windows Vista—which might have worked with the UWA-BR100—are often unsigned or use older, deprecated signature algorithms. Attempting to force-install a Windows 7 driver for the Ralink RT2870 chipset results in Error Code 52 (The driver was not digitally signed) or Code 39 (The driver is corrupted). Even when users locate generic drivers from 2010-2012, the operating system rejects them as untrusted, effectively bricking the device for standard users who are unwilling to disable core security features like Secure Boot or Driver Signature Enforcement.
