Frequently Asked Questions (FAQ)
Q: Why does my adapter only show 150M or 300M instead of 600M? A: The "600M" rating is a theoretical maximum (300Mbps on 2.4GHz + 300Mbps on 5GHz). You will only get 600M if your router supports dual-band aggregation (Turbo QAM). For most users, 150-300Mbps is normal.
Q: Does this work on Linux or Mac?
A: The OT-WUA600NM is designed for Windows. For Linux, you need to compile the rtl8812au driver from GitHub. For Mac, this adapter is not natively supported.
Q: The driver installs, but Wi-Fi keeps disconnecting. A: Go to Device Manager → Network Adapters → Right-click the OT-WUA600NM → Properties → Power Management → Uncheck "Allow the computer to turn off this device to save power."
