Types of networks
There are two types of Wi-Fi networks that, depending on the preference and conditions of the client, may or may not be beneficial. We will describe it below.
A public Wi-Fi network is one that is not protected with a password for its connection, so they do not encrypt the information that passes through its channel, it is usually easy to find such a type of network in an airport, hotel, shopping center, etc.

How to Connect to Public Wi-Fi Networks Safely
In case you must use a public Wi-Fi network, these are the tips that we present so that you can keep your data a little safe from any attacker.
