Q1: Does driver version 51220 work on Windows 11? Yes, but you must disable driver signature enforcement during installation. After install, it works normally for both 2.4 GHz and 5 GHz (if your adapter supports 5 GHz).

Q2: Will this driver give me 300 Mbps? Only if your adapter has two antennas (2x2 MIMO), your router supports 40MHz channel bonding, and the signal is excellent. Most single-antenna USB adapters max at 150 Mbps. File hash example (for verification): MD5 of rt2870

Q3: Can I use this driver on Linux? No. Linux uses the rt2800usb kernel module. Driver 51220 is Windows-only.

Q4: The installer says “No Ralink hardware found”. Why? You extracted a driver-only pack without the installer detection script. Manually update via Device Manager → Browse my computer for drivers → point to the extracted folder containing netr28x.inf.

Q5: Is there a 51220 driver for ARM64 (Surface Pro X, etc.)? No. Ralink never released ARM64 drivers. Your USB adapter will not work on Windows on ARM.
