Question 1

Installer fails or rolls back?

Accepted Answer

Run the RT3290 setup as administrator in Windows 7/8 compatibility mode. If the INF is unsigned or rejected, extract it, then use Device Manager > Update driver > Browse > Have Disk and point to the RT3290 INF. Reboot.

Question 2

Adapter not detected (unknown network controller, Code 10/43)?

Accepted Answer

Check Device Manager for an unknown PCI network device, reseat the half-size PCIe card, enable wireless in BIOS, and disable airplane mode/hardware Wi-Fi switch. Install the driver manually via Device Manager.

Question 3

Version conflicts after Windows Update?

Accepted Answer

Uninstall existing Ralink/MediaTek Wi-Fi packages, delete the device driver in Device Manager, reboot, then install the matching RT3290 package. Temporarily block Windows from auto-replacing that driver.
