But as a wireless network, Wi-Fi technology presents the intrinsic problems of any wireless technology. Some of them are:
One of the disadvantages of the Wi-Fi system is a lower speed compared to a wired connection, due to the interference and loss of signal that the environment can cause.The fundamental disadvantage of these networks lies in the field of security. There are some programs capable of capturing packets, working with your wifi card in promiscuous mode, so that they can calculate the network password and thus access it. WEP type keys are relatively easy to obtain with this system. The Wi-Fi Alliance fixed these problems by removing the WPA standard and then WPA2, based on the 802.11i workgroup.
Networks protected with WPA2 are considered robust as they provide very good security. However, many companies do not allow their employees to use a wireless network . This problem is exacerbated if we consider that the coverage area of a connection cannot be controlled, so that a receiver can be connected from outside the intended reception area (for example: from outside an office. From an adjoining house) .
The power of the Wi-Fi connection will be affected by the physical agents that are around us, such as: trees, walls, streams, a mountain, etc. These factors affect the sharing power of the Wi-Fi connection with other devices.
