Yeah, my home is cat5e (I think!) and I was only able to get 2.5 or 5Gbps to my _single_ 10GbE capable machine I had at the time.

So I ended up just buying a switch that supports 2.5Gbps over copper since it's such a huge expense to step up. Anyway, my devices are pretty much 2.5Gbps (APs, flex mini switches, etc).
