  • Cheap setup price for multiple internet sharing.

Drawbacks Of Powerline Wi-Fi Adapter

  • Decreases the network bandwidth compared to the host.
  • Can be manipulated by strangers using the same electrical line.

What To Know About Powerline Wi-Fi Extenders?

Powerline Wi-Fi extenders are one of the most widely used devices for extending the existing wi-fi or ethernet internet connectivity. It is good for extending internet coverage over a short distance in the office or home.

Similar to a Wi-Fi adapter or Wi-Fi repeater, it is a small device that uses an existing Wi-Fi/ethernet line and boosts the network by creating a separate and unique network profile.

Sometimes, you might want to connect a device to your Wi-Fi, but the device cannot track the network due to a lack of coverage.

It helps maintain the original bandwidth without any sort of data loss. That is why Powerline Extenders are a good choice for gaming and streaming high-quality content.

How Does A Powerline Wi-Fi Extender Work?

Powerline Wi-Fi extenders are compatible with any electrical sockets in the house or workstation. It can also use an extension cable as a power source.

You can directly connect the Wi-Fi extender to an internet modem or an active router using a coaxial and ethernet cable. Afterward, the device creates a bridge between the internet host (modem/router), modifies the network profile with a new one, and boosts a fresh Wi-Fi signal.

How Does A Powerline Wi-Fi Extender Work

As a result, the range of the original Wi-Fi gets extended to cover more area without any sort of network drop and loss of data packet. Sometimes users confuse a Wi-Fi extender with a Wi-Fi repeater.

A Wi-F repeater boosts the network by amplifying the frequency from the host. Whereas a Wi-Fi extender creates an entirely new profile from the physical connection via ethernet cable to generate a new range of internet connectivity.

Benefits Of A Powerline Wi-Fi Extender

  • It helps share the internet via Wi-Fi without compromising bandwidth.
  • Suitable for high-end internet connectivity such as gaming, simulation, and streaming.
  • It cannot be hacked/manipulated by strangers and neighbors.
  • A separate SSID (Wi-Fi name) and security password can help protect the connection.
  • The device acts as an independent router; thus, you can customize the settings.

Drawbacks Of A Powerline Wi-Fi Extender

  • The power socket becomes reserved for only a Wi-Fi extender.
  • Hassling of ethernet/coaxial wirings and routing the wires.

What Are The Differences Between Powerline Adapter And Wifi Extender?

It is important to know their differences to get a better clearance of the concepts of Wi-Fi adapter and Wi-Fi adapter. This will help to understand the usability of the devices before choosing one for internet sharing.

Principle of operation

A Powerline Wi-Fi adapter uses electrical signals to share the internet to a distant area. It reverts the electrical signal to a data-sharing frequency and vice versa while sending data to the receiver.

On the contrary, a Wi-Fi extender uses direct internet connectivity from the modem/router and amplifies the network to increase coverage.

External antennas

Powerline Wi-Fi adapters do not have any sort of antenna for amplifying an internet network. In comparison,  Wi-Fi extenders come with built-in antennas to extend a network’s coverage by boosting it.

Usability Of Power Socket

Wi-Fi adapters convert the power socket for further uses such as powering up any electrical devices. But, the power socket becomes completely reserved once you have connected a Wi-Fi extender to it.

Quality Of Network Security

Using a Powerline Wi-Fi Adapter is less secure than network sharing. It can get manipulated by others using the same electrical line. On the other hand, Wi-Fi extenders are Highly secured due to a separate network profile and internal ethernet connectivity.

Bandwidth Of Shared Network

Bandwidth can decrease for several reasons, such as external interferences while using a Powerline Wi-Fi adapter. Moreover, using powerful electrical appliances such as microwaves and heaters in the same socket may decrease the internet speed.

In contrast, the bandwidth remains optimum, similar to the host, while using a Wi-Fi extender. It is because a high-speed ethernet cable is used for sharing the internet.

Requirement Of Wiring

However, none of the devices require an external cable as a source of power. But Wi-Fi extenders require ethernet or coaxial cable connection to receive and boost the internet. Hence, there is a hassle of cable routing if you use a Wi-Fi extender.

Are Powerline Adapters Better Than Wi-Fi Extenders?

Both Powerline Wi-Fi adapters and extenders are good in terms of their functionality. The suitability and performance of the devices depend upon the demand of the user.

Considering you want a completely wireless network sharing to a place where it is hard to route internet cables. Then the Powerline Wi-Fi adapter works better than the Wi-Fi extender. Because the setup only requires working electrical sockets to transmit the internet data over an electrical signal.
