(The above transmission efficiency is the signal strength. Assuming that there is an old man or a child at home, and the wireless router is very close to the computer, you can adjust the transmission efficiency to 50, and it is no problem to cover a room, so reducing the signal strength can also be avoided. Unnecessary rubbing behavior, assuming that the signal feels that the signal is too poor, you might as well set the transmission efficiency of the wireless router, 100 is the maximum efficiency.)
