Windows 11 secretly throttles Wi-Fi speeds

Windows 11 limits Wi-Fi performance on devices with high-end routers. The system applies a default bandwidth cap of 100 Mbps on Wi-Fi 6E and Wi-Fi 7 networks. Users report inconsistent speeds, lag in web page loads, and game ping spikes despite strong internet plans. The issue persists after router restarts and Windows network troubleshooter runs. A 30-second manual fix involving network adapter settings resolves the throttling. This behavior affects all Windows 11 devices with Wi-Fi 6E or Wi-Fi 7 hardware.
