Ethernet and Wi Fi are two different technologies that you can use to connect your devices to the internet. They have many similarities and differences, so it is important to understand the basics of these two types of connections. When getting Internet access, some people say that Ethernet is better. It’s because it has a higher bandwidth capacity, while others say that Wi Fi is more convenient to use.

It’s not as simple as measuring the speeds with two distinct settings to compare an Ethernet connection to Wi Fi. There are additional benefits and downsides to using Ethernet cable rather than a wireless connection. Thus, let’s dive into what these two options are. We will tackle how they work together for your home or office network needs. This is so you can make an informed decision about which one might be best for your situation.

What is Ethernet?

Ethernet is a networking technology that links wired local area networks (LANs). It allows devices to interact with one another via a protocol or common network language. A local area network (LAN) is a network of computers and other electronic devices that spans a limited region in your workplace, home, room, or building.

Compared to a local area network (LAN), a wide area network (WAN) spans a considerably greater geographical region. Furthermore, Ethernet is a protocol that governs how data is transferred over a local area network.

It also specifies how network devices send and structure data packets so that they may be received, processed, and recognized by other network devices in the same area network segment.

Ethernet cables are commonly used to connect devices to a local network in order to provide an internet connection. They connect to an Ethernet port on a number of different devices. The most common usage of an Ethernet cable is to connect a WiFi router or modem to an internet entry port or a phone line.

What is Wi Fi?

Wi Fi is a technology that allows electronic devices to communicate wirelessly. This is over a shared radio channel in a chiefly outdoor environment. A WiFi-enabled device such as a smartphone, tablet, and laptop, among others, can then access the Internet via an Access Point which may be wired or wireless.

The best way to imagine this is that all the wireless-enabled devices are communicating with each other but they do not necessarily have to talk to a router or an Access Point (AP). They can simply communicate within proximity of one another.

A WiFi-capable device will be able to communicate directly with the AP; however, it is also possible for your device to connect via another WiFi-enabled device which in turn connects to the AP. If this happens, you may get slower speeds through what is known as a mesh network.

Difference between Wi Fi and Ethernet

There are several things to consider when weighing the advantages of one form of connection against another.


When it comes to speed, one choice isn’t necessarily better than the other. Many individuals will tell you that ethernet is quicker; however, they are confusing the connection’s peak speed for the connection’s real speed. Not only does your type of connection affect the speed of your internet, but also what speed you are paying your ISP for. Also, learn what to do if your Ethernet doesn’t have a valid IP address.

If your equipment isn’t capable of supporting the data speed you’re obtaining, it can restrict your speed. However, if both types of connections can handle the speed you’re getting, none is better than the other.

Wi Fi is less dependable than Ethernet. Ethernet connection is simply better due to the nature of how data are transmitted across each of these connection types. Wi Fi uses radio waves to transfer data, which is why it is wireless. However, radio waves may be prone to interference in a variety of ways, and there are few methods to protect yourself from this. As a result, Wi Fi is more prone to data loss, latency, and connection problems.

A wired connection may be secured, and it is frequently done so that data are not tampered with and is therefore unlikely to be interrupted or disturbed. This has the extra benefit of providing each device with its own connection, ensuring that bandwidth is not shared between them.


One major concern with Wi-Fi is that it can be affected by so many variables that it can be difficult to get an optimal connection going. If anything is having an effect on your Wi-Fi connection, then you will likely see lots of problems occurring like slow speeds, input-lag or connection issues with gaming, buffering when streaming movies, the list goes on.

Ethernet doesn’t have this issue. As long as the cable you are using isn’t too long and nothing is damaged, your connection will be consistent and should match the speed provided by your ISP as long as you are using the right kind of cable.


Damage to the equipment or the cable itself is the only thing that can disrupt a wired Ethernet connection. Otherwise, data may and will be sent without interruption, with little latency, and without the risk of data loss.

Wi-Fi, on the other hand, is susceptible to interference from a wide range of sources. Microwaves, Bluetooth transmitters, walls, elevation, and just about everything else you can think of can disrupt your wireless connection, resulting in service interruptions and data loss.


Ethernet is once again superior to Wi-Fi in this situation. Wi-Fi offers unprecedented convenience by broadcasting your signal for any device to connect to. This is especially beneficial for keeping your network area clean, but it also allows unauthorized devices to connect and interact with your network, sometimes with bad intent.

Performance and Stability

Ethernet wins when it comes down to performance and stability thanks to its direct-wired connection which provides faster speeds, more bandwidth, and lower latency than both 2.4GHz and 5GHz frequencies used by WiFi connections. Generally speaking, you’ll be able to achieve faster speeds on a wired connection than on WiFi.

However, WiFi is better in terms of flexibility and convenience as it does not require additional wiring or power outlets. Typically the best option is to use both technologies together which can be done by using one of many connectivity types available such as:

1. Wirelessly connect your computer to your local area network via an access point with LAN capabilities.

2. Connect an Ethernet switch into your router/modem with the help of a LAN port adapter. Then connect all devices that need good quality internet connections directly into the switch instead of the router/modem. This allows each device on the network to pick up its own IP address via Dynamic Host Configuration Protocol (DHCP) instead of sharing its IP address with all other devices on the network.

3. Use WiFi to connect your modem/router which in turn provides an Ethernet connection back to your local area network (LAN).

Can I convert my WiFi device into a LAN device?

This is possible by using either a wireless router or an Ethernet switch depending on what you wish to achieve. This would be done by connecting the device via a cable such as a crossover cable from one port on the switch or router to its corresponding port on your computer, laptop, and tablet. The result is that your computer will provide DHCP so you can take advantage of faster speeds when connected through Ethernet. However, it will also not affect any existing WiFi connections you have established in your home if they are within range.

Is Ethernet better than WiFi?

Ethernet cables were invented in the early 1970s. The Ethernet cable is not very complicated, as it is essentially comprised of two copper wires inside an insulator (the plastic sheath) and a shield to reduce interference. Numbers-wise, Ethernet is able to carry 1-2Gbps bandwidth, which is 10 times faster than WiFi, efficiently over 100m range between devices through one wire.

To put this in perspective, let us say your phone charger is able to push 1A of current – that means in one hour it will be able to fully charge your phone battery which is about 3000mAh. This means in one hour, you can get a full charge for three phones. With the Internet, an Ethernet cable can carry a couple hundred of these phone chargers worth of data through the same wire without any significant loss of speed.

Wireless devices on the other hand have been developed much more recently, and wireless frequencies have been reserved by nation-states to ensure national security from enemy attacks. The frequencies that are available for use are often mutually exclusive, meaning that you are not able to use WiFi and Bluetooth at the same time since they both will be interfering which one another. WiFi operates on two distinct bands: 2.4Ghz and 5Ghz, with the latter being much faster but also much more unable to penetrate through obstructions.

Is Ethernet better than WiFi for online gaming?

When it comes to “wired versus wireless,” Ethernet wins hands down. For a serious gamer, there’s no comparison. The problems with wireless include interference; the number of WiFi channels available in any given geographical location is small, and these can be easily jammed by other network devices located nearby.

Wired connections ensure your game packets get priority over all others for both upstream and downstream traffic on your home network so you can play uninterrupted.

You will need a good internet connection with a speed of about 20mbps or more to enjoy a wired connection since the ethernet does not have any way of compressing the data from your internet.

Wired connection guarantees uninterrupted gameplay, faster speeds, and less interference as opposed to wireless connections

Which is faster: Ethernet vs Wi Fi?

If you want a fast connection, make sure as many of your gadgets as possible are connected to Ethernet. This is due to the fact that an Ethernet connection is almost always quicker than a Wi-Fi connection from the same router.

True, radio waves travel at incredible speeds. An Ethernet cable, on the other hand, allows your devices to send and receive data instantly. This is especially true if your connection is fiber optic.

This also implies that it makes no difference how close or far you are to your router. As long as your Ethernet cable reaches, there will be minimal to no speed degradation

A quick speed test utilizing both Wi-Fi and Ethernet connections may be used to compare Wi-Fi and Ethernet speeds.

Which connection should you choose?

When deciding between WiFi and Ethernet, you must first determine how fast your internet is. Either one is as excellent as the other up to a specific speed threshold. If your internet speed is less than 1 Gbps, you’ll have to consider additional criteria to determine your best option.

A wired Ethernet connection is more solid and dependable than a Wi-Fi connection. However, Wi-Fi is incredibly handy, especially for mobile devices such as phones, tablets, and laptops.

You must determine if performance or convenience is more important to you. Ethernet is the way to go if you’re more concerned about dependability and security. If you want to roam around your house with your device and don’t mind latency, Wi-Fi is the way to go.
