To download the driver for your 450M Wireless-N Mini USB Adapter, you must first identify the actual hardware manufacturer and chipset inside the device.
The phrase "450M Wireless-N Mini USB Adapter" is a generic product description used by dozens of different manufacturers rather than a specific brand name. 🛠️ Step 1: Find Your Hardware Chipset
Because Windows needs to know the exact internal chipset (usually made by Realtek, MediaTek, or Ralink) to make the device work, you need to look up its Hardware ID: Plug the USB adapter into your computer.
Press Win + R on your keyboard, type devmgmt.msc, and press Enter to open the Device Manager.
Look for a device with a yellow exclamation mark (often labeled "USB2.0 WLAN" or "802.11n WLAN") under Network adapters or Other devices. Right-click the device and select Properties. Go to the Details tab. Click the Property drop-down menu and select Hardware Ids.
You will see a string that looks like USB\VID_0BDA&PID_8172 or USB\VID_148F&PID_7601. 📥 Step 2: Download the Correct Driver On macOS:

Realtek: If your hardware ID strings match VID_0BDA, you can safely acquire matching setup files via the DrvHub Wireless N Resource.
LB-Link: If your specific device belongs to the LB-Link ecosystem, check the LB-LINK Support Download Center.

Q: Is a 450M adapter still good in 2025? A: For basic browsing, email, and 1080p streaming—yes. But for gaming or 4K streaming, upgrade to an AC1200 (Wi-Fi 5) or AX1800 (Wi-Fi 6) USB adapter. The 450M adapter uses 2.4 GHz only, which is congested in apartments.
Q: The driver CD says “Windows 7 only.” Will it work on Windows 11? A: Possibly. Run the installer in Windows 7 compatibility mode (right-click setup.exe → Properties → Compatibility → Run this program in compatibility mode for Windows 7). If that fails, use the manual Device Manager method with the same INF files.
Q: Why does my 450M adapter show only 144M link speed? A: This indicates the adapter is using a 20MHz channel width instead of 40MHz. Log into your router and set 2.4 GHz channel width to Auto or 40MHz. Also, ensure your router is not set to “802.11b/g only” mode.
Q: Can I use a Windows 7 driver on Windows 10/11? A: Yes, in many cases. The NDIS driver model is backward-compatible. However, you may need to disable driver signature enforcement for unsigned drivers from 2012-era devices.
