Finding official drivers for this device can be difficult as it is an older model. Most modern systems require identifying the internal chipset to find compatible software:
Right-click the adapter in and select Update driver . Choose "Browse my computer for drivers" .
Copy the VID (Vendor ID) and PID (Product ID) numbers. You can paste these numbers into a search engine to find the exact Realtek or Ralink driver package that matches your hardware. Step 2: Install via Device Manager
Among the output, you should see a line similar to:
and point to the folder where you extracted the ZD1211 driver files. 2. Linux (including Raspberry Pi) This device is well-supported on Linux via the kernel driver. Install Firmware:
However, its age and specific hardware chipset mean that modern operating systems often struggle to recognize it out of the box. This article serves as the definitive archive for everything related to the CT-WN4320Z, covering its technical specifications, hardware identification, and step-by-step driver installation guides for both and Linux environments.
: Open Device Manager , right-click the "Unknown Device," and select Properties > Details . Choose Hardware IDs from the dropdown. This will confirm if it is a ZyDAS (VID: 0ace) or Ralink device.
Comtrend CT-WN4320Z is a legacy 802.11g USB 2.0 Wireless Network Adapter. Because of its age, modern operating systems may require specific manual steps or older chipset-specific drivers to function properly. Comtrend Corporation 1. Identify the Chipset This adapter typically uses the ZyDAS ZD1211 chipset. To confirm yours: Raspberry Pi Forums Device Manager , right-click the adapter > Properties Hardware IDs . Look for USB\VID_0CF3&PID_0002 USB\VID_168C&PID_0002 in the terminal to see if it lists "ZyDAS ZD1211 802.11g". Raspberry Pi Forums 2. Windows Installation (XP through Windows 11)
A: It does, but only with specific software. On Windows, using programs like "MyPublicWiFi" may work. On Linux, hostapd can technically turn it into an AP, but performance will be abysmal (often capping at 1-2 Mbps) due to the chip's hardware limitations.
Download the driver package and extract the contents using a tool like 7-Zip. Look for a folder containing .inf , .sys , and .cat files. Plug the Ct-wn4320z into a functioning USB 2.0 port. Press Windows Key + X and select .
The DriverPacks project has historically included support for this device. The specific driver version identified is . However, newer generic versions (4.13.0.0) also work and support a wider range of hardware IDs.
Only plug the CT-WN4320Z into an open USB port after the installation software instructs you to do so, or after the installer finishes and you have restarted your computer. Once inserted, Windows should automatically recognize the hardware and link it to the newly installed driver files. Troubleshooting Common Installation Errors The Device is Not Recognized (Unknown Device)
If your Device Manager shows a yellow exclamation mark next to an "Unknown Device," Windows cannot find the driver files.
Look for a device with a yellow exclamation mark (usually listed under "Other Devices" or "Network Adapters"). Right-click the device and select . Go to the Details tab. Select Hardware Ids from the Property drop-down menu.
Download the driver package (often looking for versions labeled for Windows). Extract the folder and run Setup.exe .
If the installer executable throws an error stating your operating system is unsupported, follow these steps: Right-click the setup file (usually setup.exe ). Select and go to the Compatibility tab.
