This is a classic network card. Although Realtek RTL8811AU Wireless LAN 802.11ac USB 2.0 Network Adapter #2 is not the best network card in the world, its various practical functions allow you to have a stable network environment, This network card also does a good job in terms of security. When it is connected to the router, it uses encryption algorithms to encrypt data by default, allowing you to browse information online with more confidence, The original intention of Realtek manufacturer to design this wireless network card is for those who have high requirements for network speed. Realtek RTL8811AU Wireless LAN 802.11ac USB 2.0 Network Adapter #2 can not only work well by itself, but also can be combined with wireless network cards of the same model to form a parallel working mode, so as to increase the bandwidth of the network, which can speed up the network data transmission speed, 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, The most commonly used wireless data exchange protocols are 802.11b and 802.11a. Realtek RTL8811AU Wireless LAN 802.11ac USB 2.0 Network Adapter #2 also supports these standard protocols. Using these protocols, it can be connected to various new or old router devices, Network is indispensable to any computer. Although the Realtek RTL8811AU Wireless LAN 802.11ac USB 2.0 Network Adapter #2 is very easy to use, it needs the correct driver to maximize the performance of the network card.
