Many people need a wireless or wired connection to access the internet. Wireless connections are easy to use. With them, you won’t need to battle with dangling cables.

But, some instances make Ethernet the best option over powerline. With a wired connection, you can transfer data across devices with ease. So yes, Ethernet is more suitable than power!

Today, I will examine two prominent examples of wired and wireless connections. You can then rate one over the other.

Powerline – Overview, Key Features, Benefits, and Drawbacks

This connection is an excellent means of running the internet to other parts of your building. You can install it without needing cables, which is useful when you start experiencing trouble using the internet.


You must follow certain requirements when setting up this connection. First, you will need at least two adapters to finish the setup.

One adapter can pick the Ethernet protocol passed by the router. Then, it converts the protocol into an electrical impulse. The second adapter reconverts it back so that devices can access the internet.

Key Features

Many users ask me about the adapters. They wonder how such a tiny device can give us faster speeds. Well, the answer lies in the features of the powerline device.

No Need for Extra Setup!

The connection can be effective if your home has a working wiring system. That way, it can get power to start a wireless data transfer. To achieve this, you need to set up and use an adapter.


It offers versatile solutions to network problems. For example, it lets you choose between two or more wireless connections. This connection can also transfer data through a different electrical frequency.



Such networks provide their users with convenience. You don’t need to run cables to extend the range of your wired network. Instead, you only need to plug a few adapters into a power outlet. That’s it!


An adapter is easy to carry and move around. There is no need to go through any installation or setup process. It also doesn’t affect the lifespan and performance of the device.

Reduces Demand for Wi-Fi

Using adapters speeds up file sending. People also prefer to use the internet in areas outside the Wi-Fi range.

Wi-Fi Functionality

The adapters come with extra Wi-Fi functionality. This means they can form Wi-Fi hotspots in a building and extend the Wi-Fi signals to reach the building’s dead Wi-Fi zones.

So, not only do these adapters replace Wi-Fi, but they can also boost your Wi-Fi network.


Some adapters offer security. You can use two mechanisms to secure your powerline network.

First, the adapter’s encryption is 128 bits. This means that no one can divert or stop the traffic unless you allow it. Moreover, the data signal cannot go beyond a specific location.


Slow Speed

Such adapters can be slow. The speed can be slower when you keep them in the wrong place and environment.

Besides, you may drastically lose speed if your building has poor or old wiring.

Not Handy

The network’s performance can slow down as other devices take more power. You may also experience issues using surge protectors and extension leads.

Besides, these adaptors are somewhat large. Thus, they can take ample space at power outlets.


These networks can be expensive. For example, you can find a powerline adapter that costs around $50 – $100.

Ethernet – Overview, Key Features, Benefits, and Drawbacks

Why should you own an Ethernet? I can list so many points explaining the benefits of Ethernet.

But I have discussed these points in my previous posts. Thus, I would prefer to share some quick facts about Ethernet.


Ethernet is the most common means of accessing the internet for most users. Be it fast Ethernet or Gigabit Ethernet! Besides, the Local Area Network technology further boosted the demand for Ethernet.

First, it allows seamless data, information, and file sharing with multiple devices. Ethernet works in a WAN and MAN, in addition to LAN.

Let’s check out Ethernet’s notable features, benefits, and limitations.

Key Features


Ethernet gives you a higher speed than any other wireless connection. You can achieve 1 to 10 Gbps because of a one-to-one connection. Thus, follow the right ways to get full gigabit speed.

Highly Secure

Wireless connections offer less security to users. So, I usually suggest using wired connections.

Ethernet connections allow you to control the network’s users, so you can expect high-level security while using them.

Compatible With Devices

Ethernet is suitable for use with different devices. It depends on the type of Ethernet you use. For example, you can connect the industrial PoE switch to an Ethernet-type switch.

So, there are different options in PoE switches suitable for domestic and office use. A 14-port PoE switch is ideal in an office with multiple desktops. Likewise, you can use a 4-port PoE switch to create an Ethernet network in your home.



The cost of buying and installing an Ethernet connection is low.

Easier Data Transfer

You can send data at a 1-to-100Gbps speed using a Gigabit network.


Let’s consider power usage! Ethernet is much better than a Wi-Fi connection because Ethernet cables use less power.


Limited Mobility

It’s best to use Ethernet for devices that don’t need to shift from one place to another.

Hard to Install

You may need the support of a professional to install an Ethernet connection.

Troubleshooting Problems

It may be challenging to spot the part of the network that may have issues. This happens when you notice a problem with your Ethernet connection.

What Are the Main Differences Between Powerline and Ethernet?

Below, I will highlight the vital differences between Powerline adapters and Ethernet connections.

Working and Convenience

Ethernet and Powerline connections are both great when it comes to offering solutions.

In Ethernet, you can use both wired and wireless connections on a network. It is simpler to connect as many devices as possible to the network.


Ethernet and powerline networks have different reliability structures. Most users can spot these differences.

A powerline network relies on the impulses sent over by electrical wiring. It is liable to electrical interruption. Thus, the performance of these sorts of connections can fluctuate. That’s because of electrical noise and some other determining factors.

An Ethernet network directly links with the connection source. That way, there’s minimal to no interference.

Performance and Speed

Ethernet and Powerline networks thrive on reliable speed. However, you cannot equalize their data transfer and performance speeds.

Ethernet networks have faster performance and speed. You may be disappointed at the powerline’s connection. That’s because it doesn’t always function as expected.

When Is Powerline a Better Fit Than Ethernet?

Many users wonder if choosing an adapter over Ethernet is better. Well, they are better, maybe right, as powerline adapters have proven to be a fantastic choice.

Likewise, installing an Ethernet cable can pose a big challenge. If cinder blocks or plastered walls, connections might not go through.

If you live in a rented home, investing in Ethernet might be the wrong thing to do now.

An impressive thing about a powerline adapter is its improved Wi-Fi function. That’s because we can fix it in places where signals are prone to connection barriers.

Why Choose Ethernet?

Powerline networks are an excellent choice for those with a tight budget. Still, I recommend people choose Ethernet. That’s because power lines have certain limitations.

They Need a Proper Electrical Outlet

They don’t function well, except when connected to a power source. Therefore, you can avoid surge protectors, UPS units, or power strips.

Outlet Sharing

You cannot share an electrical power outlet of the adapters with noisy devices, such as chargers and electric appliances.

In short, you must keep one separate power outlet reserved for the adapter. So, getting Ethernet to enjoy a stable network across devices is better.

Final Thoughts!

Ethernet and powerlines can both serve specific functions. By choosing either of them, you can get a reliable network connection.

But if you care about security, Ethernet is no better replacement. You must invest in an Ethernet cable and a high-quality industrial PoE switch. Go for it!
