Windows 10 blocks unsigned drivers by default. Many stable Ralink drivers are not WHQL-signed for Win10.
Six months later, Microsoft releases a Windows 11 24H2 update that finally drops legacy NDIS 5.x support. Martin’s card stops working for good. ralink 802.11n wireless lan card driver windows 10 64 bit
The most reliable approach is to leverage Windows 10’s native driver compatibility. Upon inserting a legacy Ralink USB adapter or installing an internal PCIe card, Windows Update often automatically retrieves a signed Microsoft driver derived from the last stable Ralink codebase. For many chipsets (e.g., RT2870, RT3070, RT5390), this built-in driver works flawlessly for basic infrastructure mode connections to WPA2-PSK networks. However, newer features like Miracast, Hotspot 2.0, or the latest WPA3 security protocols remain unsupported. Windows 10 blocks unsigned drivers by default
This is the core procedure. Even if you have downloaded a driver, Windows 10 may reject it due to "Hash mismatch" or "Driver not signed." Follow these steps precisely. Martin’s card stops working for good
