Driver installation: Most modern operating systems can automatically recognize and install USB wireless network card drivers, but if they are not automatically installed, you can visit the official website of the wireless network card manufacturer to download and manually install them.
Configure network: After installing the driver, open the network settings interface, search for and connect to available wireless networks.
advantage:
Portable and easy to use.
Suitable for various models of desktop computers.
The price is relatively affordable.
matters needing attention:
Ensure compatibility between the wireless network card and the operating system.
When installing the driver program, follow the manufacturer's guidelines. 2. Connect wireless router through wired connection
Step Overview:
Prepare Ethernet cable: Ensure that there is a usable Ethernet cable, usually UTP (unshielded twisted pair) or STP (shielded twisted pair).
Connect Ethernet cable: Insert one end of the Ethernet cable into the network interface of the desktop computer (usually an RJ-45 interface) and the other end into the LAN port of the wireless router.
Configure network: Set up network connections on desktop computers, usually through the operating system's network and sharing center.
advantage:
The connection is stable and reliable.
Not affected by the strength of wireless network signals.
matters needing attention:
Requires certain wiring conditions.
The length of the network cable may be limited. 3. Utilize the mobile hotspot feature
Step Overview:
Turn on mobile hotspot: Turn on the mobile hotspot function on your phone or other mobile devices.
Connect device: Connect the mobile device to the desktop computer via USB cable or Bluetooth (depending on which connection method the device supports).
Configure network: Set up network connections on desktop computers, search for and connect to hotspots on mobile devices.
advantage:
Flexible and convenient, especially suitable for use in scenarios without a fixed network environment.
matters needing attention:
May consume power and data from mobile devices.
It is necessary to ensure a stable connection between mobile devices and desktop computers. summary
When a desktop computer does not have a built-in wireless network card, wireless connection can be achieved through various methods such as USB wireless network card, wired connection to a wireless router, or utilizing the mobile hotspot function. Users can choose suitable solutions based on their own needs and actual situation. When choosing a wireless network card, attention should be paid to compatibility with the operating system, as well as the performance and stability of the product. During installation and use, follow the manufacturer's guidelines and recommendations to ensure network stability and security.
