Do Wifi Extenders Need To Be Plugged Into Router?
Wifi extenders, also known as wifi range extenders or wifi boosters, are devices designed to extend the coverage area of a wireless network. They work by receiving the wifi signal from the main router, amplifying it, and then re-transmitting it to a wider area. While wifi extenders do need to be connected to the main router, this connection is typically established wirelessly. There is no need to physically plug the wifi extender into the router using an Ethernet cable. Instead, the wifi extender connects to the router’s wifi network, allowing it to receive and re-transmit the wifi signal.
The wireless connection between the wifi extender and the main router is usually established through a process called wifi protected setup (WPS). This process involves pressing a button on both the router and the wifi extender, which allows them to automatically detect and connect to each other. Once connected, the wifi extender can begin to receive the wifi signal from the router and re-transmit it to a wider area, effectively extending the range of the wireless network. It’s worth noting that some wifi extenders may also have an Ethernet port, which can be used to connect devices that require a wired connection, such as smart TVs or gaming consoles.
How Do Wifi Extenders Improve Network Coverage?
Wifi extenders improve network coverage by amplifying the wifi signal from the main router and re-transmitting it to a wider area. This allows devices that are located far away from the main router to connect to the wireless network and enjoy a stable and reliable internet connection. Wifi extenders can also help to eliminate dead spots in the network, which are areas where the wifi signal is weak or non-existent. By placing a wifi extender in a strategic location, such as a central hallway or a room that is far away from the router, users can ensure that their devices have a strong and stable connection to the internet.
The improved network coverage provided by wifi extenders can be beneficial in a variety of situations. For example, in a large home or office, a wifi extender can be used to extend the range of the wireless network to areas that are far away from the main router.

By improving network coverage, wifi extenders can help to ensure that users have a fast and reliable internet connection, no matter where they are located.
What Is The Difference Between A Wifi Extender And A Wifi Booster?
The terms “wifi extender” and “wifi booster” are often used interchangeably, but they actually refer to slightly different devices. A wifi extender is a device that receives the wifi signal from the main router, amplifies it, and then re-transmits it to a wider area. A wifi booster, on the other hand, is a device that amplifies the wifi signal from the main router, but does not re-transmit it. Instead, a wifi booster is typically used to improve the strength of the wifi signal in a specific area, such as a room or a office.
The key difference between a wifi extender and a wifi booster is the way they handle the wifi signal. A wifi extender creates a new network, which is a copy of the original network, and re-transmits it to a wider area. A wifi booster, on the other hand, does not create a new network, but instead amplifies the existing signal. This means that devices that are connected to a wifi booster are still connected to the original network, whereas devices that are connected to a wifi extender are connected to a new network. Despite these differences, both wifi extenders and wifi boosters can be effective at improving network coverage and eliminating dead spots.
Can I Use Multiple Wifi Extenders At The Same Time?
