If the Internet ISP) speed is much slower than the WiFi speed, an extender makes no difference.
If the WiFi coming directly from the router is slower than the Internet speed, then the extender will reduce the speed of Internet for devices using the extender typically by around 50%.
Does a WiFi extender reduce speed?
Wi-Fi extenders work by ‘capturing’ the wireless signal from your router and then rebroadcasting it. If you put the repeater at the far edge of your main network hoping to strengthen the signal you will reduce the speed of your connection to the rest of the network and to the internet.
Does WiFi booster increase speed?
As you may know, the further away a WiFi device is from the WiFi access point/router, the slower its speed. So by using WiFi Network Extenders around your home, you can shorten the distance between your WiFi devices and the WiFi signal thus increasing each device’s speed and improving performance.
What is the difference between WiFi extender and wifi repeater?
Technically, a repeater just repeats the signal without any modification to it, but in practice it can boost it, too, so essentially a WiFi repeater acts as a booster. The Repeater Store uses this definition: “A WiFi repeater or extender is used to extend the coverage area of your WiFi network.
Why is WiFi extender slow?
That being said, Wifi extenders will always be slower than the actual router. This is because: The wifi extender has to split its bandwidth between interacting with the router and interacting with the clients. The wifi extender is likely to be much less powerful in terms of processing speed than your “real” router.
