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.

Public networks

Man in the Middle

Therefore, in no way should you offer personal or banking information, passwords, telephone numbers, personal images or videos, referential information, etc.

Rogue access points disguised as keyless networks

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.
