Repeater mode is not too much different; it performs the same role as Access Point mode, but the key is that it talks over WiFi instead. As such, this doesn’t get around obstacles as well as an access point does. While an access point can be put in front of an obstacle, a repeater will need to be angled around it. However, the benefit of repeaters is that they don’t need a cable to connect to the central hub.
This means if the problem with your WiFi is purely tied to distance, a repeater can be placed at the halfway point to help extend your signal. If you’re signed up to an ISP that allows you access to a public-broadcast WiFi signal, you can use a router in repeater mode to pick up the signal and beam it to your household. This is particularly useful if your Internet goes down for some reason!
