How do powerline ethernet adapters work

Most Powerline kits provide two adapters, each with an Ethernet port. The second unit plugs into another electrical outlet near the device you want connecting to the network. Without getting too technical with the hardware and software layers, the first adapter connected to your modem or router converts the Ethernet protocol IEEE Instead of relying on antennas, adapters transmit through the Line and Neutral power connectors.

All other adapters connected to the electrical system receive both power and data transmission. They filter out the latter, convert it all back to the Ethernet protocol, and push the network connection through the Ethernet port. Some Powerline adapters provide Wi-Fi connectivity too.

Powerline networking works with all wired devices that can connect to the Internet — all wireless if the adapter has Wi-Fi. All adapters synchronize and work together to create a digital map of discovered stations and their connections, for example, which is useful for network management. Since Wi-Fi is used across the world and throughout homes, businesses, and even street sidewalks, it obviously works. So, why do we need another way to connect to the internet?

Because there are situations where Powerline connections are more useful. Here are the big benefits. Unfortunately, your router is on the other side of the room. You can run Ethernet cables through your walls, along baseboards, or under your carpet, but this takes time, looks ugly, and could require lots of cables. Purchasing a pair of Powerline adapters is a faster and often more affordable solution.

There are some places that Wi-Fi cannot reach reliably. Heavy interference or extra-large houses may make it too difficult to use a wireless connection. In these cases, Powerline adapters can supplement Wi-Fi networks or help provide one-on-one solutions for devices that need a wired connection.

This may also help with other problems, like spotty streaming or slow speeds that you would like to improve. Powerline networking is easy to install. You can do it by yourself in just a few minutes. If there are only one or two devices in your home that need the Internet, Powerline may be the most consumer-friendly solution for you.

You may be wondering why you even need Wi-Fi if Powerline has all these benefits. Is Powerline better? When compared to purchasing multiple Powerline adapters, a Wi-Fi router is probably the less expensive option.

Browse the reviews of any powerline Ethernet device and you'll see a few people complain about random disconnects and slow speedsthough you'll also see a lot of 5-star reviews raving about an easy setup and great speeds. In some cases, this may be a defective device.

A lot of the time, however, the electrical wiring in the house just isn't ideal for powerline Ethernet. Maybe there's too much distance between two plugs, or maybe there's interference on the line. It's almost impossible, without consulting an electrician, to know how well powerline internet will work for you. Even if your house is ideal, the result probably won't be as fast or as stable as plugging straight into your network with an Ethernet cable.

As an alternative, consider upgrading to a router with longer range. Worried about security? Most powerline devices offer some form of encryption, so make sure you use that. But in most cases, the signal won't make it outside your home. If you own your own house and pay your own electrical bill, know that your neighbors can't use your connection even if they buy a compatible device. This is because the signal from powerline adapters is scrambled by transformers, and there is almost certainly one between your house and the outside world.

If you live in an apartment, however, there's a chance your neighbors could pick up a signal, so make sure your adapter supports encryptionand that you turn that functionality on. Surge protectors can protect your computer, but they also scramble powerline signals. Plugging a powerline device into a power bar with surge protection will severely limit your potential speed, if not stop the device from working altogether.

For the best possible connection, plug your powerline adapters straight into the wall. Though several companies make powerline adapters, they don't all play nicely with each other. If you want to ensure complete compatibility, including the use of all security functionality, it's simplest to buy the same make and model every time. There are specifications, however, meaning it's possible to get powerline adapters from different companies to work with each other under some circumstances.

The two major specifications are HomePlug and G. Generally, if you have two adapters using the same specification, they should work well together though the security protocols might not work. Really old devices such as HomePlug 1. Be sure to research compatibility before buying two different kinds of adapters. Finally, there's the powerline adapter vs. Wi-Fi question. Which is better? They need to be plugged in at the closest outlet to your router and where you want to work.

The next step is to connect the router with an ethernet cable to the adaptor, and then the 2nd adaptor to your computer or device. The first adaptor will transform the ethernet connection from the router into a powerline protocol. Data becomes transmitted using electrical signals that can travel from one part of the house to another through the wiring.

When it comes out of the second adaptor, the signal becomes transformed back into an ethernet connection that your computer needs. There is no doubt that WiFi is the most flexible connection available out there. You can literally walk all around your house with your smartphone or laptop and not worry about your connection. In a perfect world, WiFi gives strong and equal connectivity, regardless of where you are. In reality, walls will interfere with signals, and too much traffic increases the risk of slowdowns and drops.

Plus, you are more likely to lose the connection if you are only connected wirelessly, compared to a wired one. The difference is even starker when you are doing more than just web browsing, like playing games or watching videos.

You will find a powerline ethernet connection a good option for you if you have a weak WiFi connection at a particular part of your house or if you need faster and more reliable wired connection.

The same goes for you have a lot of devices connecting to the Internet at the same time and when you are transferring lots of data over the Internet. If you are a gamer, then you might find the connection much better, lowering the risks of losing your game due to unstable Internet. This kind of connection is, without a doubt, much faster than WiFi, but how does it compare to a genuine ethernet connection?

Powerline adaptors are designed to deliver the same speeds as if you are connecting directly from your computer to the router. Still, it cannot always promise to do so as some factors may affect connection speeds. If your building or home has an electrical layout more complex than others, then it might affect the speed of your Internet.

The best way to find out is to compare both connections, and if you notice the powerline is slower, then it might be due to your electrical wiring. You might also find this kind of connection-less secure, if you live in a building with other people, like in an apartment complex.
