Let us know what you try and how it works. Get the latest spec’d wifi and avoid mesh if possible. It’s just wireless feeding wireless so it would be worse. The client side will need to be upgraded if it doesn’t support the latest wifi. Keep in mind that you don’t need to have your wifi AP located where the router is. Buy another AP and locate it as close to your system as you can, You’ll need a wired connection or you’re back to using mesh. All things are possible if you want them badly enough. You might buy or borrow a long ethernet patch cable and run it along the floor just to see what you’re missing. +1 etherregen and +1 to teknorob23’s setup, but I can clearly hear things upstream. I don’t have clock for the ER yet but that is planned.
As to why it works, it must be noise and jitter and multiple types of each.
