Like all components you must consider the quality of the component. The better the component, the more important the interconnect.
I have had streamers at the$1K, 3K, 5K, 10K, and now my streamer is $22K. In general the better the component the more you get out of the connection wire. I will say that in the case of streamers, the better they are, the more they make up for poor network.
My Aurrender W20SE streamer ($22K… yes it is worth every penny in sound quality) is connected to a wall wart wifi extender, but with a high quality Ethernet cable to that. Yes, the Ethernet cable mattered.
My rule of thumb is, in general, streamer = DAC = preamp = amp in investment and wires should be around 10% of components to be optimal. They must be carefully chosen to be compatible, But that has worked for me multiple times.
