Preparing for installation and searching for driversThe first and most critical step is software preparation. Despite the presence of Plug-and-Play technology, you shouldn't rely on it, as the basic drivers in the system may be limited and not support all the adapter's features. It's best to download the full driver package in advance from the manufacturer's official website.
To do this, go to the Mercusys or TP-Link support website (as the brands are closely related). Enter the model in the search bar. MW150USIt's important to download the driver version that matches your version of Windows (32-bit or 64-bit). You can check your system's bit depth in the computer's properties.
Where can I find the driver if there is no official website?
Sometimes direct links change. In this case, you can use the hardware ID. Go to Device Manager, find the unknown device, right-click → Properties → Details → Hardware ID. Copy the top line (e.g., USB\VID_2C4E&PID_7608) and enter it into a search engine. This will take you to the required file on trusted third-party resources.
If you can't download the file to the affected computer, use another PC or smartphone to download the installer. Save the archive to a flash drive. Unzipping the archive is not necessary; the installation file is usually located inside.
Step-by-step instructions for connecting equipmentThe physical connection seems simple, but it has its own nuances that affect stability. It is recommended to plug the adapter directly into the USB port on the motherboard (at the back of the system unit), avoiding long USB extension cables or the front panel of the case, where there may be insufficient voltage.
⚠️ Caution: Do not connect the device to USB hubs without their own power supply. The adapter requires a stable current, and if it lacks power, it may constantly reconnect, causing connection interruptions.
After physically connecting, wait for the system to respond. If you haven't installed the drivers yet, Windows will attempt to find them in its database. During this time, an "Unknown device" entry may appear in Device Manager, or the network adapter may have a yellow exclamation point. This is normal before manual installation.
☑️ Checking the physical connection
If the indicator on the adapter's body lights up, power is being supplied correctly. Now let's move on to the software. Run the previously downloaded installation file as an administrator. Follow the installation wizard's instructions, agreeing to the license agreement.
Installing drivers and softwareThe software installation process is key. After running the file Setup.exe or a similar installer, you'll see a window prompting you to install the driver and management utility. It's recommended that you agree to install all components, as the proprietary utility Mercusys Wireless Utility provides more flexible settings than the standard Windows interface.
During installation, the wizard may ask you to disconnect and reconnect the adapter. This is necessary so that the system correctly associates the device with the newly installed driver files. Carefully monitor the on-screen messages and do not interrupt the process.
After installation is complete, restart your computer. This is necessary to register network services and apply registry changes. After booting, the wireless network icon should appear in the system tray (near the clock).

| Conclusion | Restart your PC | The adapter is ready for use, the indicator is on |
Setting up a Wi-Fi connectionAfter the drivers are successfully installed, you need to set up a connection to your home network. Click the network icon in the lower right corner of the screen. A list of available wireless networks will open. Find your network name (SSID) in the list.
If you're using the standard Windows interface, simply click the network name and click "Connect." The system will ask for a security key (password). Enter the Wi-Fi password, being careful not to overwrite the letters. Make sure your keyboard layout is set to English if the password contains letters.
In case of using a proprietary utility Mercusys, the interface may look different. There, you'll be able to see not only the network name but also the signal strength as a percentage and the channel the router is operating on. This is useful for troubleshooting interference. Select your network profile and click the connect button.
- 🔍 Find your network name in the list of available ones
- 🔑 Enter the correct password (security key)
- ✅ Click "Connect"
- 🌐 Check the "Connected" status in the tray
Using Access Point Mode (Soft AP)One of the notable features of the adapter MW150US The ability to operate in Soft AP mode allows you to broadcast the internet connection your computer receives (for example, via an Ethernet cable) to other wireless devices. This feature is useful in hotels or offices where Wi-Fi is paid or limited to a single device.
To activate this mode, open the adapter's management utility. Find the "Soft AP" or "Access Point Mode" tab in the menu. You'll need to specify a name for the network you're creating (SSID) and set a password to protect it from unauthorized access. WPA2-PSK encryption is recommended.
⚠️ Attention: When operating in Soft AP mode, the internet speed on connected devices will be lower than with a direct connection, since the adapter operates in half-duplex mode, receiving and transmitting data in turns.
After enabling Soft AP mode, other devices (smartphones, tablets) will be able to detect your new network and connect to it, accessing the internet through your computer. Make sure your computer already has an active internet connection.
Diagnostics and problem solvingEven with proper installation, situations may arise where the adapter doesn't detect the network or the connection constantly drops. First, check the Device Manager. If the adapter displays an error (code 10 or 43), try removing the device from the list and updating the hardware configuration.
A common issue is a power saving conflict. Windows may try to disable the USB port to save power, which causes the connection to be lost. To fix this, open the USB Root Hub properties in Device Manager, go to the "Power Management" tab, and uncheck "Allow the computer to turn off this device."
netsh wlan show interfacesThis command in the command prompt (run as administrator) will display detailed information about the wireless interface status, including signal strength and the reason for the last disconnect. This helps determine whether the problem lies with the driver or the physical radio signal.
Why doesn't the MW150US adapter work on Windows 11?
Driver signature requirements have changed in Windows 11. Make sure you've downloaded the latest driver from the manufacturer's website, marked as compatible with Windows 10/11. If the driver is out of date, try running the installer in compatibility mode (right-click the file → Properties → Compatibility → Run in Windows 7 mode).
How to increase connection speed via MW150US?
Since the adapter operates in the 2.4 GHz band, speed is affected by neighboring networks. Try changing the channel in your router settings to a less crowded one (1, 6, or 11). Also, make sure the adapter isn't obscured by metal objects and is within direct line of sight of the router.
Can this adapter be used for Kali Linux?
The MW150US model is typically based on Realtek chipsets. Monitoring and packet injection in Kali Linux requires installing specific drivers (often rtl8812au or similar, depending on the board revision) that are not included in the standard kernel. This requires Linux command-line skills.
