Possible causes are as follows: The data exchange volume of the router is too large.For example, in the same LAN composed of routers, one machine downloads software using a tool, which will reduce the network speed of other machines to the lowest point. The wireless network was rubbed.But according to you, there is no problem with the network speed when you use the cable. Your computer has a virus or the LAN has a virus Cat and router overheat.This can be caused by driving for a long time or by overheated weather. Speed is limited by wired network users through software. Advantages of wireless network: Flexibility and mobility.In a wired network, the placement of network equipment is limited by the network location, and the wireless LAN can access the network at any location within the wireless signal coverage area.Another biggest advantage of WLAN is its mobility. Users connected to WLAN can move and remain connected to the network at the same time. Easy installation.WLAN can eliminate or minimize the workload of network wiring. Generally, as long as one or more access point devices are installed, a local area network covering the whole area can be established. Easy network planning and adjustment.For wired networks, the change of office location or network topology usually means to focus on new networks.Re wiring is an expensive, time-consuming, wasteful and trivial process. WLAN can avoid or reduce the above situations. The fault location is easy.Once a physical fault occurs in a wired network, especially the network interruption caused by poor connection of the line, it is often difficult to find out, and the maintenance of the line needs to pay a great price.The wireless network is easy to locate the fault, and only needs to replace the faulty device to restore the network connection.
