Speaking as a networking professional:
You'll be wanting a switch, not a hub [but hubs are pretty rare these days anyway].
In a similar situation a while back I purchased a gigabit fanless switch - unmanaged should be fine.
The brand doesn't matter too much in my opinion.
Don't be taken in by fancy features, what I wanted [and I suspect you do too] is to have something you can plug in, and it 'just works'.
Any layer 2 switch should be able to do this.
