In the fall of 2025, just as the last amber leaves were falling over Akihabara, a peculiar support ticket arrived at Sony’s legacy hardware division.

Ground control tried everything. New dongles failed. The sensor’s firmware couldn’t be updated. The only solution: make the UWA-BR100 work on the station’s Windows 10 IoT Enterprise laptop.

Download the Driver:

Tanaka transmitted one line back to mission control: “Legacy device online. Data saved. Tell Hiroshi… his driver belongs in a museum. And on the Moon.”

To exit Test Mode:

Run bcdedit /set testsigning off and restart.

There are no official Windows 10 drivers for the Sony UWA-BR100.

Here is the important information regarding this device:

The Sony USB Wireless LAN Adapter UWA-BR100 can run on Windows 10

despite official discontinuation. By leveraging the generic Atheros AR9271 reference driver (Method 1), the vast majority of users will have a stable, working Wi-Fi adapter in under 10 minutes.
