I'm using a D Link DIR-825 dual band router, which can stream Netflix, download, Xbox live, watch youtube videos, stream from the xbox. At least. Currently I have a treadmill, two macbook pros, two wireless desktops, two xboxes, two wiis, (soon to add a wiiu and a ouya) two ipods, an iphone connected at any given time, I've had 10 or more devices actively connected at the same time. This router runs everything perfectly.
I did use a DIR-655 for a couple weeks just fine as well but I decided I wanted two bands instead for the future (hadn't signed up for netflix yet). The 655 does have better range but the 825 has all the range I seem to need so I'm happy.
I don't get people who swear off this brand or that, it's odd. Especially without trying specific products first.
