This is a classic network card. Although 802.11n USB Wireless LAN Card is not the best network card in the world, its various practical functions allow you to have a stable network environment, It supports IEEE 802.11b/g/n/ac protocol, not only can connect to most routers, but also connect to other devices that support this protocol, such as mobile phones, wireless network cards, game consoles, etc, In terms of security, because it uses a complex encryption protocol, you don’t have to worry about your information being leaked online. Even if the information is intercepted by hackers, you won’t know the real content of the information, In terms of speed, the speed of 802.11n USB Wireless LAN Card has reached the current mainstream level. It allows you to watch high-definition network videos smoothly, and it can process some simple network data packets by itself, disassemble the data packets into raw data and send them to the application layer. This will save a lot of CPU resources. But to realize this function, you must install the correct driver for it,Because it has a relatively large signal transmission power, the heat generation is also a bit large, but fortunately, it does not affect normal use. With the support of the latest operating system, the chip will automatically reduce the frequency according to the actual situation to reduce the heat generation, Network is indispensable to any computer. Although the 802.11n USB Wireless LAN Card is very easy to use, it needs the correct driver to maximize the performance of the network card.
