said by KUppiano:When Netflix is playing, I can view the charts on the DD-WRT bandwidth page. I see it flat-lined (more or less) at 3Mbps, and pretty much nothing else gets through.
That sounds a little bit like the upstream capacity may be saturated.
said by KUppiano: As I say, I'd appreciate if the one client could not hog all the bandwidth.
I'd be tempted to cap everybody at 2.5 (or so) Mbps if that's where the problem is. That way there should always be a little bit left for the next person that does something on the network.
