Wouldn't the Qos capability have to lie with the Vonage router?
Yep, the Vonage-Linksys router supports Qos, but you might have to login
to the router and config the router for your upstream and down stream
capacity.
You can find out what speed you are getting by going to
http://lax.speakeasy.net or some other speed test site. Make sure you
figure out your upstream.
Off the top of my head, I think you use http://<vonage router gateway
IP> username = <blank> password = admin.
I dont know how detailed the Vonage Qos is, but Linux/BSD would allow
you to prioritze many ques and types of traffic.
