Realtek 8723DE Wireless LAN 802.11n PCI-E NIC is a network card launched by Realtek manufacturer. Many computer manufacturers integrate this network card into the whole product, 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, The original intention of Realtek manufacturer to design this wireless network card is for those who have high requirements for network speed. Realtek 8723DE Wireless LAN 802.11n PCI-E NIC 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, 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, In general, this is a good wireless network card, worth having.
