Lan Adapter+ GC Controllers

[Tential]

I need a Lan Adapter but I also want to use GC controllers wired. So do I need to get the 2 port GC controller adapter with something like this?

Also, is the new version the one I want or the old one? I can't tell if the new one is USB 3.0.
Sorry for obvious question.
