Good and bad when you connect to the Internet

Wireless LAN using AP plus laptop wireless network card combination mode, linear communication distance of 20 meters, terminal in the basement position, AP location in the basement of the building into the third floor, in the connection to the network, the best time to connect the speed at 11Mbps, the worst is no signal.

In this case, the distance is not very long, but the wall and the ground isolation effect on the quality of communication. The change of environment moving object causes complex refraction, reflection and great change of signal intensity.

You can use the following methods to make the signal more stable some: to the wireless AP to add an external antenna, so that the signal stronger; the angle of the AP antenna to adjust, so that the radiation angle of the antenna and the basement computer network card into a vertical state; add reflective aluminum plate to the back of the AP wireless antenna Through the above methods, the connection rate should be stable some.
