Setting up a local network

I often end up programming lighting and sound for small scale shows and like to connect Qlab and Eos via OSC (often both running on my MacBook). I also use OSCRfR. I usually just use whatever network is available but would like a bit more security/ stability so I’d like to be able to set up a local network that I can use just to connect the devices I am using for show control. I am not sure where to start on this so any pointers would be very much appreciated.
