You can find several types of “wireless extender” devices on the market. Most of them have a similar purpose — to extend your wireless coverage over a larger space. But it’s important to understand the difference between devices that use a wired connection and those that use pure wireless.
Some devices rely only on wireless to carry the signal from point to point. This can lower your bandwidth and lead to a slower connection, even if it does extend that connection to a larger area.
Here’s an example: Let’s say you’re getting 600 Mbps through your high-speed internet connection. You want to stretch your wireless access, so you install a device that uses pure wireless to extend the signal to every corner of your house. It works… but the actual speed you get on your devices is cut in half, to about 300 Mbps.
The G.hn WiFi Extender, on the other hand, is an example of a wired device. It uses the electrical system in your home or building to carry your internet connection signal from your modem to a wireless adapter, which you put in another room. Only at that point does it convert the signal into a wireless one. So the distance you’re transmitting the WiFi to reach your devices is shorter. As a result, your connection speeds will be faster in those remote areas of your home.
This difference is the key to why wired extenders like the G.hn offer a more reliable solution.
