I always wonder why the home needs such high bandwidth. What are using all that bandwidth for?

For me it's about being able to ignore the lack of QoS. My wife is streaming an HD movie, our 3 iDevices start downloading some new update that just came out, I'm on Skype and doing research, it's all completely seamless, everything blows ahead at full speed.

Oh I see, even if the link quality is crap. You have the high enough bandwidth to recover.
