RTL8811AU 802.11a/b/g/n/ac WLAN Adapter

USB\VID_0BDA&PID_A811

What this hardware ID is

USB\VID_0BDA&PID_A811 is the identifier Windows uses for one exact piece of hardware. It is the reason a driver either fits your device or does not - Windows matches this code, not the name of your laptop. Here VEN_0BDA is the company that made the chip (Realtek Semiconductor Corp.), and DEV_A811 is the chip model (RTL8811AU 802.11a/b/g/n/ac WLAN Adapter).

Every driver listed below declares support for this exact code, so any of them will install on your device. Choosing between them:

Take one that lists your Windows version and architecture - the badges are in the last column.
A newer release date is usually the better start. If the newest one misbehaves, an older release is a perfectly normal fallback.
SHA-256 verified means we downloaded that file ourselves and published its checksum and contents.
