Ethernet Vs. Wi-Fi

Are you looking forward to installing internet in your commercial or residential property in Australia? With an internet connection, you will be able to access the web and perform other tasks more effectively. With the advancement in web technology, there are different ways to access internet connections on your property.

This article seeks to look into the difference between Ethernet and Wi-Fi connections. But before indulging in that, let us look at what both entail.

What Is Ethernet Connection?

This is the most popular form of local area network or LAN technology. Ethernet involves a hardwired connection to the internet by use of Ethernet cables, and these cables include Cat5, Cat6, and many others. The cables are used to tether a device to an internet router and transfer data.

As mentioned, Ethernet works on a local area network. It connects a wide range of computers within a distance of up to ten kilometres. This connection is mainly used in an organisational setting within the same building or school. Although Ethernet might look outdated because of wireless connection, it's beneficial when used for specific intensive tasks such as virtual communication and video streaming.

There are different Ethernet connections, including fast Ethernet, which provides a high speed of about 100 Mbps, and gigabit Ethernet, which provides about 1Gbps or 1000 Mbps of speed. Gigabit Ethernet has begun to replace fast Ethernet since it offers better support for video streaming and other advanced work.

What Is A Wi-Fi Connection?

Wi-Fi is a form of wireless networking technology that makes it possible for gadgets such as mobile devices, computers, and other gadgets to interface using the internet. It makes it possible for all these devices and others to exchange information with each other by creating a network.

With a Wi-Fi connection, the connectivity happens through a wireless router. When accessing Wi-Fi, you connect to the wireless router, making it easy for all your Wi-Fi-compatible gadgets to interface with the internet. Wi-Fi connection features the IEEE 802.11 standard that defines the protocols for effective communication with all your Wi-Fi-enabled gadgets.

This includes things such as wireless access points and wireless routers. It works using a wireless access point that makes it possible for wireless devices to connect to the wireless network more effectively. The wireless access points operate in the same way that an amplifier does to a home stereo.

Wi-Fi And Ethernet Connection Contrasts

After looking at both the two, let's now look into Wi-Fi vs. Ethernet differences:


One of the facts you have to know is that Ethernet is faster than Wi-Fi. With the high internet speed, you can use Ethernet in your organisation or any other place with many users. On the other hand, Wi-Fi works more perfectly when used for daily tasks. The speed is determined by the Ethernet cable you are using, but you can expect consistent speed regardless of the Ethernet cable you use.

Ethernet usually affects the speed between different devices on your entire network. For instance, Ethernet is faster than Wi-Fi when transferring files between two computers in your house. You can use Ethernet if you have many devices backing up to a NAS (Network Attached Storage), shared hard drives, and backup server.

Ethernet is also an excellent choice for devices that stream from a media server on your network. In this case, Ethernet offers you a significant boost in streaming quality. You can also use Ethernet if you want to transfer large files between two computers because you will need high speed.


Latency is also a significant factor in comparing Wi-Fi vs. Ethernet. It refers to the time it takes for traffic to move from one device to the intended destination. An Ethernet connection is the best option to reduce latency when playing online games that require reaction time to be fast.

On the other hand, should you want to stream videos, browse the web, and listen to music, latency should not be a significant consideration. Therefore, you can use Wi-Fi or Ethernet connection. With Wi-Fi, you experience a delay when the signals travel back and forth between devices and your wireless router. There is less latency when using an Ethernet connection.

Connection reliability and wireless interference

Ethernet provides a higher reliable connection than Wi-Fi as the latter experiences more interference than Ethernet. Wi-Fi is less reliable because it can affect your home layout, other electrical devices, or other Wi-Fi networks. This interference leads to several issues, such as dropped signals whereby Wi-Fi loses the signal, and you will need to reacquire it.

It can also have higher latency and reduced speed with increased interference. It is hard to quantify interference since it mainly depends on whether you are moving around with your device.

Convenience and compatibility

When it comes to the compatibility of Ethernet vs. Wi-Fi, the latter is better. Most modern computing devices such as game consoles, laptops, smart TVs, desktops, and set-top boxes feature wireless connectivity. It's also possible to get a refrigerator, microwave, or stove with wireless connectivity.

When deciding on the internet connection to use, it is necessary to know the benefits each offer.

Ethernet Connection Pros

Here are the many benefits involved in using an Ethernet connection:

Consistent speed

The most significant benefit of using an Ethernet connection is range and consistency. It's worth noting that wired signals do not fluctuate as Wi-Fi does. Data flow is usually constant from one end to the other. The data flow is also bottlenecked depending on your internet plan and the network congestion outside your house.

It is also good to know that your internet plan usually determines the maximum speed. When making your selection, you need to consider the congestion in your home or office. If many people in your home are making downloads simultaneously, buffering will happen.

The download time also increases, so you better have a better plan. To know your current internet speed, you should plug a computer directly into the modem and then perform an internet speed test. With a router combo or modem, you should have a wired Ethernet connection to get the desired results.


Ethernet usually offers a direct, physical connection to a network. So, there are no risks of hackers having access to your connection and intercepting your data or emails, as is the case with Wi-Fi. So, Ethernet connections are 100 per cent more secure than Wi-Fi connections. This gives you peace of mind knowing that all your crucial data is fully secured when sharing and accessing the web.

Less latency

This issue goes back to the Ethernets' consistent speed. As mentioned, latency refers to the time that your data takes to leave your device, reach the intended destination and also get back to you. When gaming, you require that round trip to use little time, and this is an instance in which Ethernet is the best option.

Wi-Fi has more latency because of your device location, effects of your neighbouring networks, and interference from other devices that affect your connection quality. Wi-Fi does not guarantee a consistent data rate, and at times you might lose your entire signal.


It is easy to use an Ethernet connection since you need to plug one end of your cable into the router or modem and the other end into your device. You don't have to connect to a network and manually input the password. In addition, it's easy to troubleshoot connectivity problems. All you need to do is replace and reboot the cable. However, tablets and phones do not have Ethernet ports, so you need to buy an adapter.

Ethernet Connection Cons

Ethernet connection has several shortcomings, including the following:

Limited mobility

When it comes to mobility, Ethernet connection has physical limitations. With an Ethernet connection, you won't be able to roam freely. You have to place your device in a specific place. Thus, the connection is only convenient for gadgets like desktops. If you have mobile devices, an Ethernet connection is not the best option for you.

Costly to expand

If you want to expand your Ethernet connection, you have to incur additional expenses and time. You will need to buy other switches, routers and also wire meters. In addition, an electrician should rewire all the devices you use.

Hard to install

It's hard to install an Ethernet connection without the help of an expert. Installation requires more work, especially when you want it to pass multiple floors and walls. You have to drill the areas separately and require different cables to be connected to various switches and computers.

Connection issues

Wi-Fi can be connected to several devices at one time, unlike Ethernet connection, where you can only connect to one computer at a time. If you require more connections, you have to invest in more cables.

Wi-Fi Connection Pros

Here are some benefits of using a Wi-Fi connection:

Easy setup

Ethernet cables have to reach all computers in order to work. This can get more challenging when you require an internet connection in many computers that are placed in different areas since you have to pass through walls or even under the floor to access them.

On the other hand, Wi-Fi is easy to set up and is less time-consuming. This is explicitly true if you work on wireless infrastructure in the cloud. You only need to install your access point remotely and then configure your network. You will be able to use Wi-Fi wherever you are.

Fast enough for your daily tasks

With the advancement in internet technology, Wi-Fi has become faster, making it appropriate to use in large-scale needs. You can utilise it to perform a wide range of tasks. Latency is not a big issue since the delay experienced does not affect performance when using your network to stream videos, browse online, and listen to music.


Wi-Fi uses encryption to protect data. This is important since Wi-Fi moves in the air, leading to increased risks of data interception. Data encryption helps protect your information to ensure safe connections.


Wi-Fi offers high-level versatility since it can be used to connect an unlimited number of users, allow data sharing, and simple file access and transfer. With a Wi-Fi connection, you can also move around and access the network within that area covered by the Wi-Fi range. You will not be limited to places where the router is located.

Less clutter

Another great advantage of using Wi-Fi is that you don't need to switch boxes or cables, thus eliminating clutter. Ethernet connection can make your home look like an electronic shop since you have a lot of cables running all over the place. At times you require switch boxes that are fully installed to expand your entire network to use more devices that your modem or router can accommodate.

Wi-Fi Connection Cons

Here are some disadvantages of a Wi-Fi connection:

Compromised security

One of the most significant shortcomings of Wi-Fi connections entails security. Although Wi-Fi uses encryption to enhance data security, its wireless nature puts it at high risk of hacking, especially for public Wi-Fi networks. This happens because public Wi-Fi networks are open to all, making it easy for hackers to impose fake networking IDs.

Limited range

Wi-Fi offers a limited range, mostly going around 30 to 45 metres. This may be enough for your average home usage but will not work effectively for building structures. The strength of the network reduces when you move away from the access point. If you live in a building with multiple storeys, the strength of the connection varies from one floor to the other. Therefore, you will require more access points.

Slower speed

Wi-Fi speed is slower compared to Ethernet connection. You have slower connections when you use several devices, unlike when using an Ethernet connection in which the speed is constant regardless of the number of devices you use.

Less reliable

When it comes to reliability, having a Wi-Fi connection is less reliable since it depends on the signal strengths. When the signals are weak, you experience less connectivity. Wi-Fi might not be reliable when you want to transfer large files.


Most routers can accommodate about thirty maximum devices for connection. Wi-Fi has a weaker bandwidth because it gets weak when adding more devices. When the bandwidth is limited, you end up experiencing slow speeds.

The Right Time To Use Wi-Fi And Ethernet

Now that you know how Wi-Fi and Ethernet connections work and their advantages and disadvantages let's look at when it is convenient to use each. For Wi-Fi, you need to use it when you have mobile devices. There are also instances when you cannot use Ethernet because of the complexity involved in connecting and running the cables all over the space.

If you live in a rented property in Australia, you may also have to use Wi-Fi since you may not be allowed to run cables as you want. A Wi-Fi connection is also perfect if you want to move around when using the connected device. Another important thing is that Wi-Fi is usually supported by most modern devices, making it great to use anytime and anywhere.

Factors When Installing An Internet Connection

Whether you want to install Wi-Fi or Ethernet connection in your space, here are essential factors to consider:


It's essential to consider the performance specifications of the various service connections and packages. Be sure to check the bandwidth that shows the network's capacity. This is the amount of data that goes through the connection at a particular time, shown in bits per second or bps.

Check the speed, which is the data amount exchanged over the connection within a certain period. Consider the performance level you require from the internet connection depending on how you want to use it. If you need to chat or check emails, you require a moderate connection. However, if you have a business that requires heavy internet usage, you need a strong internet connection.


You also need to consider the cost of the internet connection you choose. Note that you will be charged depending on your selected service package. Most providers charge a flat fee, but others charge depending on how you use the internet. Be sure to check on additional costs related to your internet connection, including installation costs. Choose a package offering good value for your money and one that suits your budget.
