When many people assemble their computers, they wonder whether they can plug in a wireless network card to connect to a wireless network. PHP editor Youzi has conducted detailed research on this issue. The following content will introduce in detail whether the assembled computer supports wireless network cards, installation methods and precautions to help you solve this doubt.
First of all, the wireless network card you are talking about here should be a 2G/3G/4G wireless network card, that is, a wireless network card, right?
My answer is yes. However, you also need an AP that supports USB wireless network cards, such as: (only for Jili use, not a recommended product)
Network cards are essential for modern computers. Without a network card, you cannot access the Internet, whether it is an onboard network card, an independent network card, or a wireless network card. When assembling a computer, a separate network card is generally not installed, because the current motherboards have integrated network cards, so there is no need to buy another one. However, the computers assembled now cannot use wireless Internet access like laptops, because there is no wireless network card installed. Players can Load the wireless network card yourself as needed. The computer is connected to the external LAN by inserting a network interface board into the host box (or inserting a PCMCIA card into the laptop). The network interface board is also called a communication adapter or network adapter (adapter) or network interface card NIC (Network Interface Card), but now more people are willing to use the simpler name "network card". There are two types of network cards: wireless and wired. A wireless network card is a terminal wireless network device. It is a wireless terminal device that is used to access the Internet through a wireless connection network under the wireless coverage of a wireless LAN. Specifically, a wireless network card is a device that allows your computer to use wireless to access the Internet. However, with a wireless network card, you also need a wireless network that can be connected. If there is a wireless router or wireless AP coverage at home or location, you can Connect to the wireless network wirelessly through a wireless network card to access the Internet. Wireless network cards can be divided into many types according to different interfaces: One is the PCI interface wireless network card dedicated to desktop computers; The other is the PCMCIA interface network card dedicated to laptops. One is a USB wireless network card, which can be used by both desktop and laptop users as long as the driver is installed. When choosing, it should be noted that only wireless network cards using USB2.0 interface can meet the needs of 802.11g or 802.11g. In addition to USB wireless network cards, there are also MINI-PCI wireless network cards that are widely used in notebook computers. MINI-PCI is a built-in wireless network card. Centrino models and non-Centrino models with standard wireless network cards use this wireless network card. The advantage is that there is no need to occupy a PC card or USB slot, and it eliminates the trouble of carrying a PC card or USB card with you at all times. At present, there is not much difference in price between these types of wireless network cards, and their performance/functions are also similar. You can choose according to your needs.
Assembling a computer requires a network card, but not necessarily a sound card.
The network card is a necessary component for the computer to connect to the network. It can connect the computer to the router or modem to realize the Internet access function. If your computer motherboard does not have an integrated network card, you will need to purchase a separate network card to install on your computer.
The sound card is a component used to process computer audio signals. If you need to play music, watch videos, or make voice calls on your computer, you need to install a sound card. However, most motherboards now have integrated sound cards, so if your motherboard already has an integrated sound card, there is no need to buy a separate sound card.
It should be noted that if you need to perform professional-level audio processing or games, you may need a higher-level sound card to meet your needs. But for ordinary users, the integrated sound card is enough to meet daily use needs.
If you have not installed a wireless network card yourself, check whether the motherboard has a wireless network card. Normally it does not come with it, but it is not excluded that high-end motherboards will come with it.
If you are assembling a desktop computer, the sound card and wired network card are usually integrated on the motherboard. You do not need to spend extra money to buy these accessories because they are all integrated on the motherboard. But if there is no reserved network cable socket in your home, you need to buy a USB wireless network card. Generally, the price of this type of network card is less than 50 yuan, and the performance is quite good.

Your wireless network card is short-circuited and the computer shuts down automatically. The main reasons are as follows:
1. Poor heat dissipation. The system overheats due to the influence of weather temperature or insufficient number of revolutions of the CPU fan, which may cause the computer to automatically shut down. It is recommended to check whether the system temperature is normal.
2. Memory reasons. When the memory is in loose contact with the motherboard slot, it may also cause the computer to shut down automatically. It is recommended to check whether the memory is tightly connected to the motherboard.
3. Power supply problem. Insufficient power supply is also an important factor that causes the computer to automatically shut down, but judging from this configuration, the possibility of this problem is very small.
4. Software factors. Computer shutdowns caused by viruses or Trojans are common, especially the recent popular shock wave, which will cause the system to restart and shut down after being infected by the virus. If you are using Windows 2000 or Windows XP system, it is recommended that you apply the shock wave patch in time after using anti-virus software to remove the virus, and the general problem can be solved.
1. As for whether you need a special sound card and network card, it depends on your computer needs. If you are an ordinary user who only needs to surf the Internet, work, watch videos, etc., then the sound card and network card that come with the motherboard can meet your daily needs. However, if you need to perform high-performance tasks such as audio editing and video editing, it is recommended to purchase a professional sound card to enhance audio processing capabilities, otherwise sound quality problems may occur. At the same time, if you want to perform high-bandwidth network tasks such as games or live video broadcasts, you should consider purchasing a separate network card to improve network transmission speed and stability.
2. The steps to assemble a computer are as follows: First determine your needs and budget, and choose the appropriate CPU, motherboard, memory, hard drive, power supply and other accessories. Then, connect these accessories according to the pinout diagram in the motherboard manual, taking care to avoid problems such as static electricity and cable slots. Next, install expansion cards such as graphics cards, sound cards, and network cards, and connect external devices such as monitors, keyboards, mice, speakers, and networks. Finally, turn on the computer to check whether the hardware is working properly, install the operating system and drivers, and perform system settings and software installation.
3. In short, assembling a computer requires a certain level of skill and patience. At the same time, you must choose appropriate hardware accessories and expansion cards according to your own needs and budget, and pay attention to issues such as static electricity and cable slots. In the end, Successfully build a computer that meets your personal needs.
No need, as long as it is not an antique-level motherboard and has integrated sound card and network card, you only need to update the driver. If you want to access the Internet wirelessly, the motherboard generally does not have a wireless network card, and you need to install a wireless network card.
When assembling a computer, the sound card and network card do not need to be purchased separately. When assembling the computer, the sound card and network card are included on the motherboard of the computer. There is no need to purchase them separately. When we install the operating system, he can automatically install the sound card and network card on the motherboard. When the network card and sound card are driven, we only need to insert the headset into the hole of the sound card and it can be used directly, which is very convenient
