WiFi WEP, WPA, WPA2 and WPA3  Which is Better? ▷ 2020

Since the 1990s WiFi security protocols have undergone many changes, this with the aim of making them a lot more efficient and safe. That is why we currently find different types of security protocols in charge of protecting each of home wireless networks.

This is how during all this time they have been created WEP, WPA, WPA2 and WPA3 networks, where each of them fulfill the same objective, but at the same time they differ from one another. And this is how they are responsible for keeping away the unwanted parts that they connect to the network and, in addition, they are in charge of encrypt private data that are sent through radio waves.

Therefore, here we are going to explain a little more about what each one of them is about and what they are The main differences that exists between each of them.

How many types of passwords and encryptions can a WiFi network have and what are each one for?

These are the wireless network security protocols currently there: WEP, WPA, WPA2 and WPA3, where each of them performs a similar function, but with certain differences from each other. All of them have been created mainly because WiFi networks does not have the same security of wired networks.

As usual, wireless networks transmit data within range to each of the addresses that are connected to it, which makes it is much more exposed than a wired network where they only transmit data from a point A to point B.

With this in mind, here we explain each of these protocols:



Known as Privacy equivalent to wiring, which has been developed primarily for wireless networks and approved as a safety standard for WiFi networks. This is how this tool was launched on the market with the aim of offering the same security as wired networks.

But, unfortunately this was not the case and a large number of problems were generated WEP security, as this one was very easy to break, but difficult to set up.

Until now, WEP it is still a very vulnerable alternative for this type of network. Therefore, those systems that depend solely on this protocol constantly have to be being updated or replaced with the aim of power keep the wireless system safe. Due to all these problems, WEP ended up being abandoned in 2004 by the Wi-Fi Alliance.



It is also named as Protected Access to Wifi. It was used as a temporary upgrade to what was the WEP protocol, taking into account that they presented a great quantity of faults and problems. It was just like a day before WEP officially dropped by Wi-Fi Alliance, WPA was adopted to start carrying out the protection of this type of networks.

That was how thanks to WPA began to get a improved protection of the system where most of the applications modern WPA used a pre-shared key (PSK), also known as Personal WPA, just like him Temporary Key Integrity protocol or TKIP for data encryption.

Thanks to all this, WPA became a major upgrade for what was WEP. However, as time went by and when it was put to the test and in public demonstrations, WPA also began to be quite vulnerable to intrusion.

This is how it was possible to detect that the attacks that most affected the protocol were not those that were made directly to him, but those that were made in the secure WiFi settings (WPS), which is a system developed to simplify linking equipment to modern access points.



WPA2 or WiFi Protected Access version 2, which became the improvement of WPA, taking into account that this protocol had also presented vulnerability to attacks.

This is how this new protocol had a very significant characteristic and which became the most important improvement, and that is that it had the use of the Advanced Encryption Standard (AES), which is a completely safe and legal system for what it is the encryption of information classified as secret.

However, just like previous versions also began to present vulnerability, but this time it was when the attacker already had access to a secure wireless network where could access multiple areas to perform the attacks on different devices connected to the network.

In the case of the vulnerabilities it presented WPA2 mainly affect enterprise level networks, and not directly to the networks domestic smaller. Despite all this, nowadays attacks through the configuration of WPS secure WiFi continues to have a very high average, where it currently affects WPA and WPA2 protocols.



We finally meet WPA3, This being the most up-to-date and recent WiFi security protocol. However, today most wireless connections and routers continue to use WPA2, and it is that despite having some vulnerabilities it is still safe.

But, this latest version released to the market also known as WiFi Protected Access (WPA3), seems to have all the necessary tools to be able to provide a modern security at wireless networks.

Among the main tools that he has included in his system we find what is brute force protection, where WPA3 will be responsible for protecting each of your users’ passwords no matter how weak, it offers a public network privacy, it has improved the Internet of Things and offers much stronger 192-bit encryption.

Until now, WPA3 has not reached the entire router market, but it is expected that for late 2019 and early 2020 this protocol begins to tread strongly on the market of WiFi networks. Where the manufacturers of the same have to take care of create versions that are compatible with devices that have previous versions. This is a process that can take years to fully accomplish.

WPA vs WEP How are they different and which is more secure?

When we talk about WEP and WPA we mean what were the first two WiFi security protocol versions, where WPA eventually had to replace WEP because it presented a great vulnerability to attacks, which makes this second WPA version be much safer.

In the case of WEP was used very infrequently because it showed a large insecurity rate since it could be violated very easily. It provided a encryption level 2 based on the algorithm of RC4 encryption, commonly used by 64-bit and 128-bit keys. Therefore, this protocol was not really the best.

While WPA as opposed to WEP use what is a initialization vector 48-bit, as well as a 128-bit encryption key. In addition, it stands out for using what is the TKIP, taking into account that the first version uses the same key to encrypt all packets that are transported over the network.

Thus, WPA with TKIP change all encryption keys every time one of the packets is transmitted, providing a variation in them that prevent the router can be easily accessed by third parties.

What are the differences between WPA, WPA2 and WP3?

What are the differences between WPA, WPA2 and WP3?

Currently exist three protocols called WPA, although the latter is not yet completely finished setting the market, but is expected to soon be in the routers. In accordance with this, here we present the main differences between each of these versions.

In the case of WPA it is much more vulnerable than the next two versions released. Where despite having a very solid encryption using 256-bit WPA-PSK, still presents a series of vulnerabilities you inherited from the first WEP version. Due to these failures it was necessary to crear a second version which would be its replacement in order to offer greater protection.

It was like this WPA2 became the replacement for WPA in 2006, which presented a large number of updates with respect to the previous version in order to improve what was security and encryption where the AES stood out mainly.

That was how he also introduced what was Counter encryption mode with Block Message Authentication Code Protocol, which would allow replace the vulnerable TKIP. However, this version also began to show some vulnerabilities that led to the creation of a third version that has not yet been fully released to the market.

So finally what is released the WPA3 version, known as the WiFi Alliance strikes back, which offers greater security than the previous versions offered, this is how it will offer fully updated tools offering a more advanced encryption to each of the users.

This protocol will require that all connections make use of the PMF or Protected Manageme, this being a factor that raises privacy protections with additional protection mechanisms, ideal for protecting any type of information or data.

Why should my WiFi network always have WPA2 or WP3? Benefits

Taking into account everything mentioned above, we can see that the WPA2 protocol is currently the safest and most reliable, where despite having a bit of vulnerability it is still capable of offering an excellent protection to WiFi networks.

Therefore, it is best to use the WPA2 and not use WEP or WPA, since both present a increased vulnerability and you will be more prone to suffer damage or inconvenience.

As currently the WPA3 It is not yet available in its entirety, you can continue using the previous version. However, it is best to use this last version in order to ensure a greater protection at all times, taking into account that the latter has advanced tools and updated capable of withstand a lot of attacks.

Bearing this in mind, Here we give you the main benefits of using one of these two protocols in your WiFi network:

  • You avoid having weak access networks to your system.
  • The WPA2 despite being vulnerable, it has a very strong protection system that will help you to have greater protection in your private data.
  • You could have data in open networks more protected.
  • They offer you greater ease at the time of device configuration.
  • In the case of WPA3 offers you a greater length of keys.
