Problem with them, every repeater hop cuts the bandwidth in half.

May I have a more detailed explanation of your post, please. Inquiring minds want to know why a repeater cuts band width in half. Does that apply to all repeaters? What about over air to wire repeaters?

Thanks

WiFi communicates one way at a time. For example.

Device to Access Point
Access Point to Device.

Now, when you add a repeater.
Device to Repeater
Repeater to Access Point
Access Point to Repeater
Repeater to Access Point.

Now, add another repeater.

Device to Repeater 1
Repeater 1 to Repeater 2
Repeater 2 to Access point
Access point to repeater 2
Repeater 2 to Repeater 1
Repeater 1 to Device.

Now, the 2nd one, you may not think it halved it again, but in reality, it does. Add another hop, and you are halved again.

This isn't necessarily so if you use a repeater/amplifier that has two separate radios. In my WiFiRanger setup I have two separate routers, each with its own radio. One is only involved in connecting to the AP, the other with communicating with devices on my network. There still is some bandwidth loss, but it isn't as large as you indicated.
