How To Connect WiFi Extender with Ethernet

There’s nothing more frustrating than an internet connection that is slow. If you’re using Wi-Fi connectivity, you’ll be faced with this problem frequently in the office or at home. There are many tricks you can use to boost the speed of internet connectivity via your Wi-Fi connection. One of them is to use Wi-Fi extenders, where you have be able to plug in the Ethernet cable directly to Wi-Fi extender. The question is, can extenders with Wi-Fi really increase internet speed?

When you connect an Ethernet cable to a Wi-Fi extender, the internet connections flow via the cables to your device. The extender connects to a modem or router, and then extends the area of connectivity. However, first, you need choose the Wi-Fi extender with an Ethernet port, as the majority do not come with the port. This article we’ll examine whether connecting an Ethernet cable to a Wi-Fi extender will improve the speed of your internet or if it is better to opt for a different option such as the booster or repeater.

What Is a Wi-Fi Extender?

A Wi-Fi extender basically expands the coverage of wireless networks. You must connect the Wi-Fi extender with your router so that you can expand your wireless networks. You can put the extender so that the signals are weak, to allow it to extend the coverage area quickly.

So, a Wi -Fi extender needs to be placed between your router and mobile devices that are standalone, such as your smartphones. To summarize it all the Wi-Fi extender expands the reach the router has. It actually broadcasts the wireless signal, without any modifications.

Is There Any Ethernet Port on Wi-Fi Extenders?

Instead of broadcasting wireless signals which may become weak based on the distance between the router, it’s preferential to broadcast wired signals. That means, instead of connecting wirelessly to the router it is best to connect a Wi-Fi extenders to routers via a wired connection, which can be the Ethernet cable, in this instance.

However, the majority of Wi-Fi extenders don’t come without an Ethernet port. This is due to the fact that the purpose of the extender is to expand the wireless signal to ensure that devices connected to it can connect wirelessly too. However, some extenders include Ethernet ports. They are ports for input,, which means that you can connect devices, such as computers, for internet connectivity directly from the extender.

However, the extenders may not come with the output Ethernet port to which you are able to connect the router to ensure a stable connection. This is the reason it is crucial to check the Ethernet port as well as the type that comes with the Ethernet port(input/output) prior to purchasing an extension device for Wi-Fi. There are Wi-Fi extenders from TP-Link which come that have Ethernet ports to ensure a stable connectivity on both ends.

What Happens When You Plug The Ethernet Cable Into Wi-Fi Extender?

The Wi-Fi extender broadcasts the same packets as your router , and it’s primarily utilized to connect Wi-Fi within the smallest of places at your office or home. To ensure that the connection is stable and reliable, you connect Ethernet cables to extenders for Wi-Fi. In this way the extender is now an extremely strong access point, and it is able to rebroadcast WiFi signals at the same speed as the router. The extender also can establish an additional Wi-Fi network, and it is possible to connect to the extender without the router to gain internet connectivity. Here are the results from Ethernet cable on various aspects of the internet.

Effect on Internet Speed –

Ethernet cable is able to provide speeds of up to 10 gbps, while the modern Wi-Fi routers can provide an internet speed of 1 gbps. But, you can’t expect to experience 10gbps speed when you connect an Ethernet cable to your computer since your internet service provider offers different plans , each with different speeds.

In addition there are other differences, as in addition, different Ethernet cables come with different speeds for internet, which can be used to provide capacity. This means that you must buy a suitable plan and purchase a compatible Ethernet cable as well as router. If you intend to connect an Ethernet cable in your wireless extension device, ensure that the extender is compatible with the same speed for internet access the same as that of your ISP plan in order to achieve the speed you want.

Effect on Latency –

The most basic rule of the latency of an Ethernet cables is the longer Ethernet cable is the greater amount of the latency you will have to endure. But the result is insignificant since it’s just one millisecond for each foot. So, it’s certain that you don’t need to be concerned about latency when you plug in an Ethernet cable into your Wi-Fi extender because it’s length won’t be that long.

Wi-Fi Extenders or Mesh Networks – Which Is Better?

While Wi-Fi extenders merely broadcast signals received from the router while mesh networks seek out the most efficient path to reach the router, and give a greater coverage effectively. They work on the basis of dynamic routing and therefore mesh networks can be costly in comparison to extenders. Mesh networks require nodes throughout the structure, and these nodes could include Wi-Fi boosters or extenders.

You can be assured that quality of the signal will remain strong due to the dynamic routing. It is possible to connect an Ethernet cable with any node to improve connectivity. This is why a mesh is believed to be the genuine extender of Wi-Fi networks. So, a mesh system is superior to a Wi-Fi extender so long as budget isn’t a problem for you.

MoCA – Better Than Ethernet Cable?

If you plan to make use of a hard-wired connection You can choose MoCA rather than Ethernet cable. It’s a coaxial connection but it’s an old technology. MoCA is typically utilized to connect TV and cable boxes. So, if you only own a coaxial cable in your office or at home and you want to connect it to the internet, you can utilize MoCA to get better internet connectivity. It is essential to buy an adapter that it works with Wi-Fi devices. It is possible to get an internet connection using a wired connection, where Wi-Fi falls beyond the range. So, if you want to upload or download large files it is the right option to use. However, Ethernet cable is more reliable than MoCA with modern technology for network connectivity.


Connect an Ethernet cable to a WiFi extender if you’re looking for a hard-wired connection. This can help you get an internet connection that is stable, as the Wi-Fi signal can become weak. The speed of your connection will depend on the plan as well as the capacity that the extension device can provide. If you decide to purchase an extender for Wi-Fi, make sure it is equipped with an Ethernet port to input and output ports to connect to your router quickly.
