It must be much faster than the network cable, and a network cable now supports at least 100M speed, which can ensure full speed operation. The wifi2.4g rate is generally 40-60m, in the transmission process, through the wall or loss of wifi speed will be reduced to 10m or even a few m, the rate is greatly reduced. All under the condition of being able to connect the cable, the cable connection rate is the fastest and most stable, and only under no conditions can the wifi be connected.
Wifi and network cable are essentially the same, the speed is affected by two aspects, one is the bandwidth, one is the number of connected users, the same bandwidth, the same number of connected users, the theoretical speed is about the same.
