Is a network card the same as a WiFi card and the solution to troubleshoot an unresponsive wireless network card

Apr. 19, 2024 / Updated by Seraphina to Windows 11


A network card is a hardware device in a computer, primarily used for data transmission between the computer and the network. It acts as a bridge between the computer and the network, responsible for converting the data generated by the computer into a format understandable by the network and vice versa. Simply put, a network card is an interface device that facilitates communication between a computer and a network.

1. Network Card:

A "network card" typically refers to a network adapter in a computer, also known as a Network Interface Card (NIC), used to connect a computer to a network. It allows computers to communicate with other devices via networks, such as Ethernet or Wi-Fi protocols.


2. WiFi Card:

A WiFi card (Wireless Network Interface Card) is a hardware component in a computer or other device used to connect to a Wireless Local Area Network (WiFi network).


It typically consists of several parts:

1). Antenna:

WiFi cards usually contain one or more antennas for receiving and transmitting wireless signals. These antennas can be small antennas built into the card or external movable antennas.

2). Radio Frequency (RF) Receiver/Transmitter:

WiFi cards contain built-in RF receivers and transmitters to receive signals from wireless routers and send data to routers. These components are responsible for receiving and transmitting WiFi signals.

3). Circuit Board and Chipset:

The circuit board and chipset inside WiFi cards contain electronic components for processing WiFi signals, such as modulators, demodulators, and RF amplifiers. These components process received signals and convert them into data understandable by the computer.

4). Interface:

WiFi cards typically connect to the computer motherboard or other devices via PCIe slots, USB interfaces, etc., for communication with the devices.

3. Types of Network Cards:

1). Wired Network Interface Card (NIC):

This card connects a computer to a network via wired connections (e.g., Ethernet cables) and usually uses Ethernet technology for communication.

2). Wireless Network Interface Card (NIC):

This card connects a computer to a network via wireless connections (e.g., WiFi signals) and is often built into laptops or mobile devices or can be inserted as an external device into desktop computers.

3). Dedicated Network Interface Card:

This card has specific functions or purposes, such as cards dedicated to high-performance computing, servers, or specific applications.

4). Integrated Network Interface Card:

This card is integrated into the motherboard or other devices and cannot be replaced or upgraded separately.

5). High-Speed Network Interface Card:

This card supports higher data transmission speeds and is typically used in scenarios requiring large data transfers, such as data centers or large networks.

4. Are Network Cards and WiFi Cards the Same:

Network cards and WiFi cards are not entirely the same, although they often play the role of connecting to networks in computers. A network card (NIC) is a general term used to describe hardware devices that connect computers to networks. It can include both wired network interface cards (such as Ethernet cards) and wireless network interface cards (such as WiFi cards). On the other hand, a WiFi card (Wireless Fidelity Card) is a specific type of network card designed specifically for wireless network connections, typically referring to wireless network cards installed in computers or other devices for wireless network connections via WiFi signals. Therefore, while a WiFi card is a form of network card, network cards are not limited to WiFi connections and can include other types of network connections, such as Ethernet connections.


5. PC Wireless Network Card:

A PC wireless network card is a hardware device installed on a personal computer (PC) to enable the computer to connect to a WiFi network via wireless signals. It typically includes antennas, RF receivers/transmitters, circuit boards and chipsets, and interfaces connecting to the computer motherboard. The role of a PC wireless network card is to allow PCs to connect to WiFi networks without physical wired connections, enabling wireless network communication and data transmission.

6. Intel Network Card Drivers:

Intel network card drivers are software provided by Intel Corporation to support and manage Intel network card devices installed on computers. These drivers allow the operating system to communicate with Intel network cards and ensure their proper operation. Users can download and install the latest drivers applicable to their specific network card model and operating system from the Intel official website or other trusted sources to ensure network connection stability and performance.

7. Troubleshooting Steps for Unresponsive Wireless Network Card:

1). Hardware Issues:

The wireless network card itself may have hardware problems, such as poor connections, damaged interfaces, or components. This may require replacing the wireless network card with a new one.

2). Driver Issues:

If the computer does not have the appropriate wireless network card drivers installed, or if the drivers are damaged or outdated, the wireless network card may not work properly. 

Download Driver Talent

  • It is recommended to use software like "Driver Talent" to detect and repair the computer, download and update drivers with one click.


  • After the update is complete, restart the computer to ensure that the updated network card drivers are effective. 

  • Alternatively, you can resolve this issue by reinstalling the wireless network card drivers.

3). Power Issues:

Some wireless network cards may require additional power supply to function properly. Ensure that the interface into which the wireless network card is inserted provides sufficient power.

4). System Configuration Issues:

There may be certain system settings or security software that prevent the wireless network card from working properly. You can check the system settings and security software to ensure they do not block the operation of the wireless network card.

5). Interface Issues:

Sometimes, the computer's USB interface or slot may have issues, causing the wireless network card to fail to connect properly. Try inserting the wireless network card into other available interfaces to rule out interface problems.


The above are the methods for troubleshooting an unresponsive wireless network card. If you encounter driver-related issues with network cards, graphics cards, Bluetooth, sound cards, etc., you can use "Driver Talent" to detect and repair them. Additionally, "Driver Talent" supports driver download, installation, backup, etc., providing flexible driver management options.
