Apple sells an Ethernet adapter for $30 that will let you plug a network cable directly from the Mac to the Ruida, similar to the way you use USB. It’s reliable, has no driver issues, and is about 2x faster. You often have to toggle off WIFI to do it, but the setup is pretty straightforward otherwise.
We’re also discussing providing a Raspberry Pi program to let you connect to the Pi using WIFI or Bluetooth, and have the Pi relay to the Ruida controller with a network cable. It’d be pretty easy to set up, and would let you use WIFI from the Mac (or PC) reliably, which you can’t do at the moment.
