What is a WiFi extender and how does it work?
A WiFi extender is a device that boosts the coverage of your existing WiFi network by rebroadcasting the signal from your router to hard-to-reach areas. It works by receiving the WiFi signal from your router, amplifying it, and then retransmitting it to create a secondary network.
This secondary network is typically a separate network with its own SSID and password, which can be configured to match your original network. WiFi extenders are usually plug-and-play devices that can be placed in areas where the WiFi signal is weak, such as upstairs or in a basement, to provide a stronger and more reliable connection.
Do all WiFi extenders require an Ethernet cable?
No, not all WiFi extenders require an Ethernet cable. WiFi extenders can operate in two modes: wired and wireless. Wired mode requires an Ethernet cable to connect the extender to the router or a wired device, while wireless mode uses WiFi to connect to the router.
In wireless mode, the extender receives the WiFi signal from the router and rebroadcasts it to create a new network. However, some WiFi extenders may require an Ethernet cable to set up the device or to provide a wired connection for devices that don’t support WiFi. It’s essential to check the specifications of the WiFi extender to determine if it requires an Ethernet cable for operation.
