Using a weak password or not having one
The first step to having a secure Wi-Fi network is to establish a password for the internet signal emitted by the router. A keyless network can be exploited by cybercriminals to use it as a door to the connection of others devices such as computers, laptops, cell phones, televisions or sound equipment.
In general, it is not necessary for a password to access the grid be extremely long, but there does have to be some level of security.
Keys like “password” either “QWERTY” are too common and easy to guess to even consider them as options within the possible passwords. Therefore, it is suggested to include in it a word or phrase with a number of characters greater than 12, in addition to having uppercase, lowercase, numbers and special characters.

In the case of router, older models stop receiving support updates, which translates to less security.

Usually, the companies that manufacture these devices have a password generation system that is not really random, so it cannot be guaranteed that they cannot be violated by cybercriminals. It is preferable to modify this password for a personalized one that takes into account the additional security criteria previously indicated.
