I guess everyone will agree with the statement that Wi-Fi has many advantages. In order to use the Internet freely, you do not need to plug in a cable, and you only need a network adapter that works in this standard. The Wi-Fi network is simple to set up and is often used to create local, urban networks that enable nearly all mobile users, whether phones or laptops, to use Internet resources without problems.

However, the Wi-Fi network is very prone to interference and therefore we may have trouble communicating if there are several other networks within our network, such as neighbors from the block.
