How do Wi-Fi extenders work and do you need it?


If you are stuck in a space where Wi-Fi waves do not reach, you may be tempted to drill holes in the house and lay some Ethernet cables. However a Wi-Fi extender is the fastest and most excellent way to extend the distance of your wireless network.

In this article we will explore Wi-Fi extenders, what they do and how to use one.

What is a Wi-Fi extender?
Wi-Fi extenders are sometimes called "repeaters" or "boosters" but the purpose is the same. A Wi-Fi extender sits between the wireless modem (router) and your computer exchanging messages between them.

Of course the way the Wi-Fi extender makes the connection depends on the model. On the whole they connect to the router initially in order to know from where it should route the internet. The extender must then be connected to a power source, an outlet between the router and the computer.

Once the extender is up and running, it creates its own Wi-Fi network where others connect. When you connect a device to it, all traffic passes through the Wi-Fi extender. When it receives traffic from the computer, it automatically redirects it to the router where it was initially connected.

Use Wi-Fi extenders to cover long distances
In its most basic function, a Wi-Fi extender serves as an intermediary for your computer and router. For example if your computer is too far from the router it will receive a weak signal that appears with a line on the Wi-Fi indicator. However at the point where the amplifier receives the signal, it may have average power, with two or three lines.

By placing the extender at this midpoint, the router and computer transmit traffic over an average signal transferring more traffic. As a result, performance increases and the number of disconnections decreases.

These small devices can do more than cover the distance. For example did you know that some materials can create Wi-Fi death zones? If there is something blocking the signal, instead of trying to overcome the obstacle by force, you can use a Wi-Fi extender.

You need to place it at a strategic point where obstacles between the router and the Wi-Fi extender and between the Wi-Fi extender and the computer are avoided. The idea is to place it in an area where it can signal the router and the computer without being blocked by an obstacle.

Do I need a Wi-Fi extender?
Wi-Fi extenders are a choice for addressing Wi-Fi death zones. As such all you need is a Wi-Fi connection. If you have a stable connection, an extender can increase the Wi-Fi signal by several levels.

Before buying an extender you should first try out what things. Your signal may be weak due to the positioning of the router. First make sure they are in a good position.

You can also modify the router itself by changing the channel to see if the signal will get better. You can also try replacing the antennas.

If nothing solves the problem, then you should try a Wi-Fi extender. Before buying such a device, first check the old electronic devices for a router. Some of them can even serve as Wi-Fi extenders.

If this method also fails then you need to buy a Wi-Fi extender.

What are dual band Wi-Fi extenders?
While searching for Wi-Fi extenders you will find some labeled as "dual-band." A device with this label means it covers 2.4Ghz and 5Ghz bands.

The 5Ghz band has higher traffic speeds than 2.4Ghz but the latter traverses higher distances and penetrates walls more easily.

Dual band expanders are also good on the compatibility of many devices. Some devices do not work at 5Ghz for example a budget smartphone only operates at 2.4Ghz.

What do the numbers on the Wi-Fi extender names mean?
Where does a Netgear N300 Wi-Fi extender differ from a Netgear N600? The answer is simple. The N300 can transmit traffic at a maximum speed of 300Mbps while the N600 at 600Mbps.

The higher this number, the more traffic the Wi-Fi extender can carry. If an extender has only one band, for example 2.4Ghz, the maximum speed it can transmit is 300Mbps.

If there are two bands, the speed will be higher. For example a dual-band Wi-Fi N750 expander can transmit 300Mbps on the 2.4Ghz network and 400Mbps on the 5Ghz network.
