QoS for Vonage and P2P in Thibor 14.
Upstream Bandwidth: Test your Upstream Bandwidth using any valid
testing tool (with QoS turned OFF on your router), then confirm that
the "Auto" setting is close to your tested upstream. If it is
not, change the setting to Manual and set the number to about 90% of
your tested upstream bandwidth.
Device Priority: Enter your Vonage MAC address and set the priority to HIGHEST.
Ehternet Port Priority: I disabled Flow Control on mine, it seemed to make QoS work better. Your mileage may vary.
Application Priority: Not a lot to do here. If you have
certain services you want to prioritize, set them here. I'd set
DNS to High, since it doesn't take a lot of bandwidth. If you
have performance problems with other services, set them to Medium or
P2P QoS: P2P should always be set to Low.
