What is a Wi-Fi extender?

A WiFi extender is a wired or wireless device that helps you increase the signal range of your WiFi router. This essentially acts as a bridge between a WiFi extender, WiFi router, and wireless devices. Many people call Extender a WiFi repeater, WiFi booster, or WiFi signal booster. They signal rebroadcasts to improve your WiFi connection, so they are similar to Extender but work differently.

How do Wi-Fi extenders work?

Once there is a connection between the Internet-connected device and the router, the Wi-Fi Extender (sometimes known as the Wi-Fi Range Extender) captures the current signal and then separates it from its position, acting Re-broadcasts on the channel as a middle-man to relay the connection. It provides a wide range of wireless signals throughout your home. You need to find the right place for a Wi-Fi extender because it should always be close enough to your router to catch the signal quickly, but far enough away to re-broadcast that signal to that room or area. Where you need strong home Wi-Fi.

How to install wifi extender?

Below is a general set of instructions that apply to most extenders:

  • Connect the WiFi Extender to the WiFi Router

First of all, you have to plug in the extender to the power plug in the same room as the wifi router. Some extenders require you to press the WPS button on both devices to connect. To complete the installation you have to open a specific website. After syncing the extender with the router, you can move it to the required location and plug it into the wall outlet.


  • Choose the Locations for the WiFi Extender

You need to place your extender in a strategic location. We recommend placing it where it should be close to the router to receive a strong signal, but it is sufficient to transmit the signal in the desired location. Some extenders have wired connectivity as an option with an Ethernet port that can be used to connect a wired device. If you have wired devices, you should use a fast Ethernet cable to connect the device and the WiFi extender.

The benefits of WiFi Extenders

  • This greatly increases your WiFi coverage. It also extends to your backyard.
  • All your wireless devices maintain a stable signal and will experience high speed
  • Every room in your wifi network gets improved
  • They eliminate dead areas around their home by bypassing the walls and building materials blocking the WiFi signal.

How to connect your wireless device to WiFi Extender?

Whenever you connect your mobile device to your router, you will have to do this by accessing the settings on your phone. You select the network name that matches your router and enter a password to access the Internet

Whenever you connect your mobile to the router, you should do this while accessing your phone settings.

By default, the network name of the WiFi extender must be the same as the name of your routers, but will eventually be written with EXT (short for Extender)

for example:

Router Name: Home WiFi Network

Extender Name: Home WiFi Network EXT

Remember, if you have multiple extenders, you need to change the default name.

Which wifi extender would be best for my needs?

There are three types of WiFi extenders:

  • Single-Band WiFi Extenders

A single-band extender has the ability to transmit frequencies up to 2.4GHz. Due to the frequency, the signal has a better ability to travel through obstructions such as walls, furniture, and floors. However, many devices such as older cordless phones, baby monitors, and microwaves use 2.4GHz frequencies. Due to the different devices that use the same frequency, it makes you experience slower speeds. Also, since signal-band extenders receive and transmit signals at the same frequency, single-band extenders allow up to 50% of their bandwidth Lose.

  • Dual-Band WiFi Extenders

The dual-band extender is one of the most common extender, with 2.4GHz and 5GHz transmission capabilities.They are able to use both frequencies to communicate between devices; It can be used to communicate with a WiFi router once and another to transmit its signal. As a result, fewer devices interfere with the signal, and since they have more bandwidth, you are able to experience higher WiFi speeds.

  • Tri-Band WiFi Extenders

The Tri-Band Extender is one of the best extenders. It offers two 5GHz bands and one 2.4GHz band to provide you with WiFi coverage. Your devices experience minimal interference, fast WiFi speeds, and long-distance coverage. A Tri-band extender (also known as mesh extender) is commonly used for mesh networks - a group of devices that act as a single WiFi system.

Do WiFi Extenders Work Effectively?

Yes, the wifi extender works.

The location you place the wifi extender is very important. To get a strong signal, you need to place the WiFi Extender closer to the router, which will give you stronger signals, as long as the WiFi Extender is placed in a good location, you can see a quick improvement in all areas where you Faced with dead spots and a weak wifi connection.

You can try this test too.

To do this test, before you install Extender, you do a speed test. You go to different rooms and test the upload and download speeds. After installing Extender, do a speed test again in the same room. Write the results down so that you can compare the before and after results.

Is the wifi extender safe?

Yes, WiFi Extenders are safe because they typically use security like traditional WiFi: WEP, WPA, and WPA2.

WPA and WPA 2 are much better to use than WEP. Therefore, you should use it only if you want a more secure extender, make sure the extender you provide supports WPA or WPA2.
