What a Wifi repeater/extender slow down the wifi speeds?

    Speed is not the same as latency.  Each mesh hop increases latency by a factor.  For normal browsing or streaming, it won't be noticed.  But for gamers, it might.

    Any wifi/wifi extender has to negotiate clean air on one side to receive and clean air on the transmit side.  Wifi radios cannot transmit at the same time, so that is why they must negotiate this.   That is where the latency increase occurs.

    Wifi extenders can often cause the wifi to slow down.  Additionally some devices have trouble with them as you move devices through the house.  This is why people who need extenders should be upgrading to mesh networks and adding as many mesh nodes as they need.  As it is today extenders are largely obsolete.

    you need to place it halfway between the router and the device for best results.

    there is also a maximum limit on distance, and wifi doesn't go through lots of walls well. hanging it higher helps.

    Yes, it will slow down the wifi and add ping, but your wifi usually has way more speed than your internet so you will notice the ping more.

    A repeater gets a Wi-Fi signal from your router and reboradcast it from the repeater in order to increase the range of the Wi-Fi.  There is going to be some latency in this process, but it can not rebroadcast the signal "instantly".  But it is only going to be a few milliseconds of delay.  Have used a repeater to reach a back bedroom that is in an addition to my house and so separated from the rest of the house by several yards.  I have never seen any significant decrease in speed or performance when on the extended Wi-Fi.

    If you have an average size house, you can usually eliminate the need for a repeated by simply relocated the router to a more central spot in the house.  Since it is Wi-Fi, it does not have to right next to any of the computers.  Relocate it to the middle of the house and your problem is solved.

    It will slightly increase latency but you theoretically shouldn't notice it. It should be seamless.

    Most houses don't need extenders unless you live in 3000 sq foot house or have a weak antenna array to begin with.
