Total starvation of anything but the first flow, for example, in the native tests. Do you have the exact version number of the 1900ac's default firmware you tested. (I've seen it fall apart on 2 flows, too). I can hardly imagine the number of users that don't wipe out the default firmware and just live with this *crap*. However, I'd have recommended you try 900mbit to see if cake/etc does the right things, not 975mbit. Dave T=C3=A4ht Let's go make home routers and wifi faster!
