Understanding WiFi Repeaters and Extenders
Before diving into the pros and cons of each, it’s important to understand what WiFi repeaters and extenders are and how they function.
WiFi Repeater
A WiFi repeater is a device that captures the signal from your existing wireless router, amplifies it, and then broadcasts the enhanced signal to a broader area. It essentially creates a new network, typically using the same SSID (network name) as your primary router, but sometimes it may create a new SSID.
WiFi Extender
A WiFi extender, on the other hand, also aims to improve coverage but usually connects to your router via a wired connection (Ethernet cable) and then broadcasts a new WiFi signal. This can eliminate the bandwidth reduction seen in repeaters, as the extender doesn’t have to split its bandwidth between receiving and sending data wirelessly.
