Many homes suffer from slow internet speed because of a shared internet connection. Even with just 2 devices sharing the internet, speed and performance can become poor, depending on your infrastructure. This is where TRENDnet Powerline 1200 AV2 Adapter Kit comes in. It pumps up the active network and expands the range throughout the entire home.

The TRENDnet Powerline 1200 AV2 Adapter Kit (Model TPL-420E2K) connects up to 8 devices to the internet. It uses the already-installed electrical power system to do so, which is great for connecting many gadgets like personal computers, smart TVs, media players, and/or game consoles.

Without having to install anything on your operating systems, the adapter is plug & play and works right away. It works right out of the box to connect to an outlet immediately for an extremely fast network connection. Additionally, it’s a secure system as it’s already pre-encoded from production, so no one outside of your household can connect to it.


The TRENDnet Powerline 1200 AV2 Adapter Kit (Model TPL-420E2K) is extremely easy to use. Just plug it into an outlet and connect an Ethernet cable from your device to the adapter.

The adapter transmits signals into the electrical line so that other devices can effortlessly connect to the internet when they would otherwise not be able to.

To explain the difference, WiFi uses an invisible signal to transmit data without any cables or wires. Although WiFi is often preferred, sometimes it’s just not an option. Powerline technology uses the electrical lines in the house to send data throughout the network.

If more devices from other rooms need to connect, just plug in another adapter to the wall and connect the device into the adapter. There are no extra cables that lie around the floor to get the adapter to work.

The TRENDnet Powerline 1200 AV2 Adapter Kit shares the internet network across many places without clutter. It will not lose the network strength that a conventional router does even with many simultaneous users since it’s using a hardwire connection to transmit and receive data.


There are 5 good reasons why the TRENDnet Powerline 1200 AV2 Adapter Kit (Model TPL-420E2K) makes a great investment for home owners.

First is its Plug and Play quality. TRENDnet’s ready to use adapter is good to go out of the box and needs no CD or drivers installation. It can plug immediately into the wall for instant connectivity, and its pre-encoded setup makes it safe and secure from unauthorized use. Even when neighbors can potentially see the Powerline network, they won’t be able to use it without the owner’s permission.

Second is Coverage. Its range of distance reaches up to 1,000 ft. of connectivity, making it a suitable choice for even large homes that have a ton of area and space. The amount of coverage needed to cover a large home is often times impossible for wireless routers alone. TRENDnet’s powerful coverage reaches far places in houses that wireless routers simply can’t reach. Home materials such as concrete walls and other materials make it hard for the common WiFi router to reach every nook and cranny. This is what it’s so good at – it extends the network’s reach to all of the corners in the house where there’s a need for internet service.

Third is Signal Strength. It’s a reliable device for most internet providers because of its super stable network signal. It allows seamless streaming of high definition videos, online gaming, downloading, and browsing without any lag or latency issues.

Fourth reason is the speed. Just one of TRENDnet’s Powerline 1200 AV2 Adapter Kits provides up to 1200 gigabytes per second for one device. Even if many devices connect to the network, each of them receives their own 1200 gbps connection from its own adapter. This leaves them with a seamless connection for intensive internet use.

Fifth is that no extra wires are needed to connect many adapters and devices. All that’s needed is the adapter plugged into an outlet and the electrical device connected to each other. No messy cable connections lay on the floor.
