I mean that if I start uploading to FTP on my laptop, it makes the connection unusable for other computers on the network. Loading webpages is pretty much a no-go. I'd like to have a solution that is a little more dynamic than capping every program at half of my maximum upload speed.
The ZyXEL P-663HN-51 seems to have a lot of options for QOS, I just haven't quite figured out how to tweak it to my liking. I'm trying to make video streaming on my Roku priority 1, HTTP traffic priority 2, HTTPS (port 443) priority 3, and FTP priority 4. I've had good success with this using DD-WRT in the past, but I was wanting to stay with just one device for the network if possible.
