Having Wi-Fi intruders is a major problem as it affects network performance and can even compromise your security. You could also have legal problems if someone connects to your network and commits a crime. Therefore, it is essential to maintain security and prevent this from happening. In this article we are going to talk about the main error that can cause someone to enter your Wi-Fi. We are going to give you some tips so that this does not happen.

Leaving the password that comes in the router is an error
The worst mistake you can make with your Wi-Fi is not having a password, but even if you do have a password, it’s a mistake to leave the factory one . The problem is that many make this mistake. They contract the Internet, they install a new router and they leave the password that comes from the factory and they do not change it. Yes, better that than nothing but it is not ideal if you want to avoid intruders.
It is essential that you use another password and do not leave the one that comes from the factory. It might be easier for an attacker to break into the network, provided they have the necessary knowledge and tools. Ideally, you should create a key that is totally random, that you can’t easily memorize. For example, it is a mistake to put your name, date of birth and the like.
You can always help yourself with a password manager to create a really strong one. It comes in very handy, since you can put different settings, such as having upper and lower case letters, numbers and other symbols, as well as having a good length. This will give you greater reliability.
Changing it from time to time is also a good idea. That will prevent problems in case there is a leak or vulnerability. It is the same as you should do in any account you use on the Internet, for example. You can change it from time to time and that refreshes the security.
The type of encryption is very important
But something very important is that you should not only have a good password. Something also essential is to use correct encryption to protect the wireless network. If you get this wrong, you may have a very good password but you would still be unprotected and an intruder could break in.
What does it mean to use bad encryption? For example, use encryption such as WEP or WPA. They are outdated ciphers, which you should no longer use. A hypothetical attacker could use tools to exploit these ciphers and even steal the Wi-Fi access key. It is another mistake that you should avoid. For example, they can use Aircrack-ng to steal Wi-Fi.
Ideally, you should use WPA-3 encryption, which is the most current. However, you can also use WPA-2 as long as you have the router updated. This encryption is supported by the vast majority of devices today, which WPA-3 is not yet. It will give you the security you need to avoid problems. You can easily modify it in the router configuration.
In short, as you can see, it is a mistake to keep the password that comes with the router. You must configure a different one, that is strong and complex. In addition, it is convenient to use a current encryption, since if you use an old one, they could still enter your Wi-Fi network without you knowing it.
