Wi-Fi or Cable Internet Connection Which is better and how do they differ?

The Internet has become one of the most common tools to communicate, work, entertain ourselves and more. Today we know two ways to connect: through the wireless network Wireless Fidelity (WiFi), and by network cable (Ethernet).

WiFi gives us comfort, it gives us the opportunity to connect many devices at the same time in a simpler way. Meanwhile, Ethernet is often more complex because of the amount of cables and their installation between walls to improve the presence, which implies a much greater expense.

However, it is the most recommended connection, since it has a continuous data transmission (upload and download) that allows us to reduce the level of lag, and currently is the one that offers the highest data speed. If you want a more secure connection with low latency, here we will present you which one is better and what are its differences.

Ethernet and WiFi What are they and how do these Internet connections differ?

There are differences between Ethernet and WiFi connections, even though both were designed to allow us to access the Internet.

We commonly use both connections, because in our homes and offices there are both desktop computers that use Ethernet and smartphones that use WiFi, which means that we want to know what they are and what their differences are. Ethernet, in terms of technology, is the IEEE 802.3 protocol, it should be noted that Ethernet is a simpler term.

This connection is the most usual local area network or what we know as LAN (Local Area Network) in conjunction with the WAN (Wide Area Network). It is used by means of cables that connect to our equipment providing us with Internet access.

On the other hand, Wireless Fidelity, in Spanish means “wireless fidelity” technically speaking it is IEEE 802.11. It works through a router or Router that emits the signal, providing Internet access to various electronic devices that do not have an Ethernet connection. It is important to note that the closer we are to the Router, the better the connection.

There are some relevant points that make these connections different, so we must take into account the following:


For many the installation is usually a bit complicated, however, with the help of a professional or simply reading the manual, you can have either of these two connections installed in a simple way, in both, there are notable differences that we will present below:

  • Ethernet is made by cables that go from a network interface or NIC (Network Interface Controller), to a modem that connects to your PC. The cables are by category and the most recommended for better data transmission are category 5 and category 6, this implies better connectivity to the Internet
  • In contrast, WiFi connects to the same interface only as with a router, which allows data to be transmitted wirelessly. However, the transmission may have interference with respect to the distance between the device and the signal source.


It is a series of steps that are basically made to have the interface, modem or router, providing signal through cable or wireless network. It is important to mention that each configuration will depend on the Software installed in our equipment. By means of the Ethernet connection, the configuration is usually done once and is automatically connected to the equipment.

In the WiFi network configuration a key must be placed for access, this to provide better security to the connection and this must be placed on the devices that want to access the network.

Number of teams

There is no doubt that WiFi has the ability to connect to the network through various devices with the convenience of not having cables that do not allow us mobility anywhere in our home or work.

Ethernet can only connect one computer at a time, unless you have a multiswitch. However, both can be connected to different devices, although this is under certain conditions.


It can be said that speed is quite relevant, since we always want better data transmission at all times, both upstream and downstream, although it will depend on the service plan we hire, there is a difference between both networks that we will see below.

Ethernet connectivity is faster and capable of exceeding 300 Mbps. On the other hand, WiFi currently has a limit of 150 Mbps to approximately 300 Mbps according to the standard.


As we have mentioned before, accessing the network through a wired connection is less possible, since for that to happen you mostly have to connect directly to the interface or modem.

Now, the one that’s easiest to crack is WiFi. Today you can scan the password from one smartphone to another without having to display it and you’ll have access to the network in an instant. Besides, you can hack it through applications that exist on the Internet. In short, the most secure connection so far is the ethernet connection.

What are the main advantages of ethernet cable connections?

Ethernet is the most used network because of the particularity of being direct to our equipment establishing a much faster and secure connection. The different advantages that it offers us are presented below:

  • Taking advantage of bandwidth: the speed is much higher, since the connection by WiFi, has limits on data transmission of up to 300Mbps, Ethernet exceeds them, and does not suffer interference from distance or other factors as with WiFi.
  • Security when sending information: Since we do not know who is trying to access our information via the wireless network, the use of encryption is necessary for the connection via WiFi, while data transmission via cable allows us to protect our information.

What are the main advantages of WiFi Internet?

For convenience and aesthetics, WiFi connections are frequently used, and are designed for devices that do not have an Ethernet connection. Therefore, in this section we will tell you what the advantages of wireless networks are.

  • Wireless connectivity: the ease of connecting anywhere we go, with just a password to surf the Internet will be very simple.
  • No wires: it’s no secret that many of us are uncomfortable with Ethernet cables, especially when they’re not installed on the walls as convenient. That’s why WiFi provides us with convenience when connecting.
  • Connect different devices: this allows us to connect at the same time from different computers. Although your connection may be unstable in some ways, with a good service plan we can enjoy this wireless connection to the fullest.

What is WiFi 6 and how can it increase the transfer speed of wireless networks?

The Wireless Fidelity network over time and like all technology, is making advances to exponentially improve the speed of transfers and along with it their use. This time we’ll tell you how WiFi technology has advanced.

WiFi 6 is the evolution of WiFi. However, before continuing you should know that this new development requires compatibility with devices and networks. In other words, while your older protocol equipment will be able to connect, it is the equipment designed for WiFi 6 that will be able to enjoy the benefits of this new generation.

The WiFi Alliance has decided to improve the technology and use of this wireless network over time. To distinguish them, it will use a waveform identification between networks with their generation number. It shows improvements in data transmission speed of up to 10 Mbps, when the maximum of the previous one could be up to 7 Mbps, this because it combines the 2.4 GHz and 5 GHz spectral bands, both for upload and download.

So what’s the best Internet connection? Cable or WiFi?

After all the work we have done in this article, we can answer that each user chooses which connection is better and which one fits their need. However, technically it is better ethernet as it clearly provides more speed and security, while WiFi is more practical.

Therefore, the use you make of your network will define what you want to use, as well as being able to use both in an alternative way.

How do I properly set up a wireless network so that the Internet is not stolen?

We have indicated that the wireless network is the most vulnerable as mentioned above in terms of security, which is why we want to guide you in what will be a correct configuration so that you do not get robbed of the Internet:

  • Initially we must access Router’s configuration, this through the browser of your preference, where you must enter a web address: http:/ or http:/
  • Then a new window will ask you for the router’s username and password (this information can be found in the box or instruction manual). You must bear in mind that the best way to recover the previous configuration (in case something goes wrong), is by making a backup.
  • You will need to change the password to a more secure one, just like the user, (try to include letters, numbers and symbols).
  • Changing the security key, which is not the same as the access key to the network configuration, is the most important step.
  • Go to the WLAN basic configuration, select the option “Authentication mode”, then WPA/WPA2; then you will go to the option “Encryption mode” where you will find an option that allows us to change the password. We recommend using upper and lower case letters, numbers and special characters. Once you have finished, select the “Apply” button.
  • Remember that you have changed the security key, so you will have to reconnect your devices by entering the new key.
