In the two buildings have two rate 11mbit/s AP, straight distance of about 60m, close the window can not connect. Move the network card and AP to the window, open the window to establish the connection, but the data transmission is not stable.
The wireless signal penetrating ability is limited, the signal weakens after the penetration is normal. To make the distance longer or enhance the data transfer capability, you can buy a separate antenna. Otherwise, the transmission speed and stability of the wireless signal will be seriously affected by the environment. If there is no matching antenna, it can improve the connection state by adjusting the antenna angle and the product position, and reducing the interference of the environment signal. In addition, you can change the speed of 22MBIT/S wireless product network card and AP, transmission performance will be better.
In the case of funds allowed, it is recommended to purchase high-speed wireless equipment, whether transmission speed, or signal transmission distance and stability, will have a greater improvement.
