On Pi4 when using any remotes/keyboards which use USB wifi 2.4GHz 
receiver you may experience problems with range due to interference from 
USB 3.

See 
https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=245607&p=1502072#p1499138

The symptom is that they work from a few inches away but not from say 10 
feet. The solution is to use a USB extender cable and plug the USB wifi 
2.4GHz receiver into that.

I have experienced this on my Pi4 which has a USB 3 sata adapter 
connected to an SSD running Raspbian Buster.

The problem affected my Logitech K400 keyboard, and various mini wifi 
keyboards.
