Here is an illustration of how a Wi-Fi Extender works:

The Wi-Fi extender (shown in blue) has two antennas. One antenna receives the signal from the router (shown in green). The other antenna rebroadcasts the signal, extending its range.

The devices (shown in red) that are connected to the Wi-Fi network will connect to the extender, which will then connect to the router. This way, the devices can still access the internet even if they are in a location where the signal from the router is weak.

The Wi-Fi extender is usually placed in a location that is halfway between the router and the area where the signal is weak. This will help to ensure that the signal from the extender is strong enough to reach all of the devices that need to connect to the internet.

Here are some of the factors to consider when choosing a Wi-Fi extender:

• The size of your home or office
• The number of devices that will be using the Wi-Fi network
• The type of Wi-Fi technology that your router supports
• Your budget

It is also important to place the Wi-Fi extender in a central location that is in range of your router and the devices that need to connect to the internet.

Here are some of the benefits of using a Wi-Fi extender:

• Improved Wi-Fi coverage: A Wi-Fi extender can extend the range of your Wi-Fi network, so you can get a better signal in areas that are currently weak or dead zones.
• Reduced buffering: A Wi-Fi extender can help to reduce buffering when streaming videos or playing online games.
• More devices can connect: A Wi-Fi extender can allow more devices to connect to your Wi-Fi network at the same time.
• Less interference: A Wi-Fi extender can help to reduce interference from other devices, such as microwaves and cordless phones.

Here are some of the drawbacks of using a Wi-Fi extender:

• Can slow down the network: A Wi-Fi extender can slow down the network, especially if it is not located in a central location.
• Can add latency: A Wi-Fi extender can add latency to the network, which can make it feel slower.
• Can be complicated to set up: Some Wi-Fi extenders can be complicated to set up, especially if you are not familiar with networking terms.

Overall, Wi-Fi extenders are a great way to improve the coverage and performance of your Wi-Fi network. However, it is important to choose the right extender for your needs and to place it in a central location.
