Repeater

Meaning

A repeater is a device that picks up a WiFi signal and sends it on again to extend coverage, often with some loss of speed on the repeated link. It is simple and inexpensive to set up, which makes it a common first fix for a weak corner of the home, but it works best when placed where the original signal is still reasonably strong. Mesh systems and wired access points usually perform more reliably, and fixed devices should use a cable where possible.
