Is LAN better than Wi-Fi?

It is always challenging to choose one type of connection or another for our house, but, you should not get carried away among the multiple options that are available to you and choose the one that suits your needs. Now we tell you about the differences between WiFi and LAN and which one is best for you.

Wi-Fi vs. Ethernet
Between WLAN and LAN, there is a fundamental difference that you probably already know: WLAN works wirelessly, while LAN based on cable data transmission. Including this primary feature, we talk about what is behind the two terms.
WLAN stands for Wireless Local Area Network. A wireless network where communication between computers done through the radio. A problem related to the use of WLAN is low security since the cryptographic standard is not enough at present. If you choose a WLAN and want to be sure to surf a secure network, you need additional security measures. The WLAN is composed of network nodes, each of which forms a radio cell. Communication between network nodes is possible as long as the radio cells overlap.
LAN stands for Local Area Network and, as the English word suggests, it is a network computer system in a small space, such as a four-wall office. The LAN Network characterized by a high data rate and a low error rate. Another advantage is the lower risk of hacker attacks compared to WLAN.

Which connection to use?
Today, activities of daily life and work are carried out on the Internet. For many, the Internet is an essential tool to carry out most of its operations. Which network is right for your business? Wireless WLAN or LAN with cable connection?
The practicality wins between WLAN and LAN
From a technical point of view, the LAN exceeds the WLAN. Especially in terms of security, the cable network is superior. There are more and more successful hacker attacks through unauthorized access to the WLAN. It is also possible to interfere with WLAN signals in other ways, for example, with the so-called Jammers, which cause the wireless connection to stop working. Creating fake WLAN networks is a common practice for hackers to obtain private data and passwords. These types of attacks are completely ineffective in LAN implementation networks. An attacker would need physical access to the computer to enter the system. It makes the LAN extremely secure.
In addition to the security factor, a connection through the LAN is much faster. Instead, several devices connected to a single WLAN simultaneously can weaken and slow down this type of connections. Even structural elements such as concrete walls or swimming pools can disturb the connection of a WLAN. The significant defect of the LAN is the lack of practicality and the disorder caused by the cables that must reach the device. In many cases, mobility and practicality of the factors always prevail over safety and speed when preferring the wireless connection.

Does Ethernet affect WiFi?
Connecting to the Internet via Ethernet is more secure than WiFi
If we think in terms of communications security, the battle for wireless connections is lost if we compare them with Ethernet. There are many types of attacks that can be carried out remotely, both to an unauthenticated device and to break the encryption key and enter the network.
When to use WiFi and LAN cable?
Now is the time to decide when each type of cable is most suitable. Whenever we can, we can use the wire, but specific devices that don�t allow it. Here we talk about smartphones or tablets, which left out of the debate. The issue focuses on laptops, desktops, and other network equipment.
If we want to transfer files at maximum speed between devices, the Ethernet network cable will be the most suitable. Here the speed that we have contracted to access the Internet is not important so that we will look for the maximum cable performance.
Can I use WiFi and LAN at the same time?
You can use the router via Ethernet and Wi-Fi at the same time, which is not a problem, configure it in multipoint and create the regular local network, the only particularity that in the wireless you put the IPS in the TCP IP of the wireless connection, and in the other on the Ethernet.
In conclusion, it is logical that the most suitable way to transfer files at maximum speed between devices is the Ethernet network cable. While the dream of not using more cables for devices is already possible, in many cases for speed lovers, it is not the best option. Therefore, it will be a matter of prioritizing your tastes.
