Physical connection and preparation for installation
Before beginning software configuration, you must properly connect the hardware to the computer. It is recommended to use the USB ports located on the rear panel of the system unit, directly on the motherboard. This will ensure a more stable power supply and reduce electromagnetic interference, which often occurs near the front connectors of the case.
If you use an extension cable or USB hub without external power, the connection speed may be unstable. Adapter The device is sensitive to voltage drops, so a direct connection to the computer port is the preferred option. After inserting the device into the port, the operating system will attempt to automatically detect the new hardware.
When connecting, you may hear a system sound indicating the device is detected, and a notification will appear in the system tray. If nothing happens, check to see if the LED on the adapter is lit. If it's not lit, this could indicate a problem with the USB port or the device itself.
☑️ Pre-installation check
Finding and installing drivers for Windows
The most critical step is installing the correct software. The included disk may contain outdated driver versions, so the best solution is to download the latest version from the manufacturer's official website or trusted resources. DEXP WFA-152 Drivers from the Realtek chipset are often suitable, since this is the company that produces the internal components of the device.
The installation process in Windows 10 and 11 often occurs automatically through Windows Update. If the system reports that the driver is not found, you will need to run the installer manually. After running the file setup.exe Follow the installation wizard's instructions, agreeing to the terms of the license agreement.
In some cases, manual installation may be required through Device Manager. To do this, right-click the Start menu and select the appropriate option. Find the device with a yellow exclamation mark or an unknown device, right-click it, and select "Update driver."
Manual search path: Control Panel → Device Manager → Network Adapters → Right-click → Update Driver Software → Browse my computer for driver softwareBy specifying the folder with the unzipped driver files, you will allow the system to install the required component. After successful installation, you may need to restart your computer for the changes to take effect.
Setting up a wireless network connection
After the drivers are successfully installed, a Wi-Fi icon will appear in the lower right corner of the screen. Clicking it will display a list of available wireless networks. Select your network from the list and click "Connect." If the network is hidden, select "Hidden network" and enter the name (SSID) manually.
When entering your password, please pay attention to the case of letters. Security protocols WPA2-PSK Character-sensitive. If the connection fails the first time, try deleting the network profile in settings and creating it again. This often helps reset erroneous authentication parameters.
Advanced users can configure a static IP address if required by their local network configuration. For typical home environments, leaving the IP address set to obtain automatically (DHCP) is sufficient.
| Parameter | Default value | Recommended value | Description |
|---|---|---|---|
| Opening hours | Infrastructure | Infrastructure | Connection mode via router |
| Security protocol | WPA2-Personal | WPA2/WPA3 | Data encryption type |
| Channel | Auto | 1, 6, 11 | The least noisy channels |
| Channel width | 20 MHz | 20/40 MHz | Affects speed and range |
⚠️ Caution: When using public Wi-Fi networks, avoid transmitting sensitive information. Even if a connection is established, your traffic can be intercepted by attackers.
Speed optimization and interference elimination
Wireless connection speed directly depends on the number of obstacles between the adapter and the router. Walls, mirrors, and household appliances can create significant interference. If you're experiencing low speed, try repositioning the antenna or moving the system unit closer to the signal source.
In the adapter settings in Device Manager, you can find the "802.11n Mode" setting. Make sure it's enabled. It's also worth checking the "Channel Width" setting. Setting it to 20 MHz can improve stability in apartment buildings where the airwaves are clogged with neighboring routers, although it will reduce the maximum speed.
How to check signal strength?
In the command line, enter the command 'netsh wlan show interfaces'. The 'Signal' line will display the signal strength percentage. A value below 50% is considered low and may cause connection drops.
Using USB 3.0 ports can sometimes interfere with 2.4 GHz Wi-Fi adapters. If you're experiencing stability issues, try switching your device to a USB 2.0 port (usually black, as opposed to the blue USB 3.0 port).
