Having intruders in our network means that it will work badly, that the speed may be weak or we will not even be able to connect other devices. This makes it critical to prevent this problem from occurring and always keep security in mind. Now what is the main reason which allows a intruder enters the Wi-Fi? In this article we are going to talk about it. As you will see, it is a fairly common cause, but it is very easy to prevent it from happening and maximize the security of the wireless network.
Bad password, the biggest problem for Wi-Fi
It is undoubtedly the biggest reason why an intruder can enter the Wi-Fi network. we put a bad password and that will mean that the network is exposed and someone can enter without us noticing. Although it is the main security barrier, the truth is that many users continue to make mistakes in this regard.
What does it mean to have a bad Wi-Fi password? For example a bad key is leave the one that comes from the factory. The normal thing is that the router brings a password established by default and if we leave that password it can give rise to an attacker with the necessary knowledge to be able to exploit it and access the network.
Another example of a bad password is putting a password that is easy to remember. Although we know that it is an error, the truth is that the most used passwords continue to be of the type “123456” and similar. These types of keys will be the first that any intruder will try to see if they are lucky and can enter.
In addition, it should also be mentioned that it is a mistake to use passwords that can relate us. For example, using our name, date of birth, mobile number… Although it is something easy to remember, the truth is that an attacker can try this type of data and get into the Wi-Fi.
How is a good key for Wi-Fi
So, what should we take into account to use a good Wi-Fi password? We are going to show some essential tips that you must put into practice so as not to have any type of problem and that there are no intruders that can affect your Internet connection without you realizing it.
The first thing is change factory default password. It is relatively easy to know the password of the router. Forget about leaving the one that comes configured with the router, since that is a mistake. You must use a totally new one, which meets a series of requirements to be considered safe and thus not have security problems at any time.
And those requirements go through using a unique key, random and that you do not use elsewhere. It is important that it has letters (both uppercase and lowercase), numbers, and other special symbols. In addition, it is a good idea to change it from time to time to further enhance security and keep it always present.
But beyond the key you use, it is also important the encryption type. Do not use those that are obsolete, such as WPA or WEP. Use the most modern ones, such as WPA2 or WPA3. In this way you will be more protected.
