What Is WiFi card ?

A WiFi card is an essential hardware component in both laptops and desktop PCs that allows the computer to connect wirelessly to the internet and local area networks by transmitting and receiving data through radio frequency signals, eliminating the need for physical network cables and enabling users to access online services such as web browsing, video streaming, online gaming, cloud computing, virtual meetings, and file sharing from various locations within the network’s coverage area.

The advantages of a WiFi card include high convenience and mobility since users can move their devices freely, easy installation especially for built-in or USB WiFi cards, support for advanced wireless standards such as WiFi 5, WiFi 6, and WiFi 6E which provide faster data transfer speeds, lower latency, improved network efficiency, and better performance in environments with multiple connected devices, as well as improved connectivity options through dual-band or tri-band support.

However, the disadvantages of a WiFi card include susceptibility to signal interference from walls, electronic devices, and other wireless networks, potentially slower and less stable connections compared to wired Ethernet, limited signal range depending on the quality of the WiFi card and router, higher power consumption in high-performance wireless adapters, and reduced performance in older or low-end WiFi cards that may not fully support modern network standards.

Proper Maintenance of WiFi Card :

• regularly updating network drivers and operating system software to ensure compatibility, performance, and security

• keeping the device and internal components clean to prevent dust buildup and overheating

• ensuring that internal or external antennas are properly positioned and not damaged

• avoiding physical impact especially for laptops and internal PCIe cards

• using secure network configurations such as strong passwords and encryption

• operating the computer in a stable environment to maintain consistent connectivity and extend the lifespan of the WiFi card.
