Network Switch

A switch is the upgrade to a hub.  It's not really an audible benefit.

What a switch would allow for is multiple separate communication streams.  Useful in business when you have A talking to C and B talking to D.  The Switch would allow those 4 devices to communicate in isolation and at maximum throughput.  Otherwise, A, B, C and D would share the same bandwidth, slowing them each down.  

However, if you have 3 devices streaming from the internet, the isolation benefits here are diminished. 

Still, switches are cheap, your modem has one built in, and it's been years since I even saw a true Ethernet hub as opposed to a switch.

you won’t know unless you try it. we can reason and type and read all day...

these questions are only answered by doing the work to set up a proper experiment and listening
