Sony UWA-BR100 is a discontinued USB wireless LAN adapter originally designed specifically for Sony Bravia TVs, Blu-ray players, and home theater systems. Sony does not provide official drivers for using this device on Windows 10, as they recommend it only for use with their dedicated home entertainment products.

The Sony UWA-BR100 was originally designed to enable Sony Bravia TVs to access internet video content. It is a specialized piece of hardware, based on standard Wi-Fi chipsets but often locked down by Sony’s proprietary identification. When plugged into a Windows 10 machine, the operating system attempts to identify the hardware. Unlike modern "plug-and-play" devices, Windows 10 often fails to automatically locate a compatible driver for the UWA-BR100. This results in the device appearing in Device Manager as an "Unknown Device" or under "Other Devices" with a yellow exclamation mark, rendering the adapter useless for connecting to Wi-Fi networks. sony usb wireless lan adapter uwa-br100 driver windows 10
