If you are trying to get a CNet CT-WN4320Z USB 2.0 WiFi adapter working on a modern Windows 10 system, you have likely run into a common issue: the device is listed as "Unknown Device" or Windows Update cannot find a driver automatically.

Because the CT-WN4320Z is an older legacy device (USB 2.0), CNet has stopped updating the official drivers for Windows 10. However, the hardware is still functional. To get it working, you need to identify the specific chipset inside the dongle and install a compatible driver.

Here is the step-by-step guide to getting your CT-WN4320z running on Windows 10.

Many users assume that because Windows 10 has a generic "Realtek Wireless LAN" driver, it should work. However, the stock Microsoft driver (dated 2013) lacks proper support for WPA2-PSK with AES and Wi-Fi 4 (802.11n) on this specific chipset. The adapter may connect but drop packets constantly. A proper driver from 2019 or later resolves these issues.

Since official drivers do not exist, use the Ralink RT2870/3070 driver set (last updated for Windows 8.1, but functional on Windows 10).
