1. Improve the stability of network connection. Reduce the problem of WiFi disconnection and delay, especially when multiple devices are connected to the network, and maintain a stable network state. 2. Enhance the network transmission speed Support high-speed network protocols, such as Gigabit network cards, which greatly improve the efficiency of downloading, uploading and data transmission. 3. Adapting to diverse network environments It can be compatible with different network types such as wired and wireless, and meet the needs of home, office and other scenes. 4. Reduce the equipment network load Handle network data independently, reduce the CPU burden of the equipment and ensure the smooth operation of the equipment. 5. Expand the scope of network connection Some wireless network cards have wide signal coverage, which can solve the problems of weak network and difficult connection in remote areas.
