I remember my first distro was Ubuntu 7.04. There was no Pipewire or Pulseaudio, only Alsa. By default it was not possible that two applications could play sound at the same time. It was only possible after some config hacking… I don’t miss those times.

did you give RCX a try?

I’m no expert but from my experience it is the other way around: Upload speed increased, Download speed decreased. Which makes sense because the outgoing data is boosted by the wind whereas the incoming traffic has to overcome the wind. If you want to increase download speed I suggest placing a hoover behind the router.
