Huge swing in QoS from day -> night

Hi gang, I'm a recent subscriber. I have noticed at night, that I am getting pauses in my phone calls using Vonage. I'll be talking, and for about 2 seconds I can't hear or be heard. It happens every minute or so.

After looking here for solutions, I ran the QoS test. At about 7PM last night, my QoS was 31%. I tried hooking my laptop directly to the cable modem, and got roughly the same result (about 34%). This would deduce that it's not a problem with lines in my house, or the router configuration (Linksys adapter is connected to a D-Link DI-614+, on it's DMZ).

I tried the QoS test again this morning (8:30AM), and my score jumped to 91%! My upload download speed was fractionally higher, but not significant. I understand the test taked many other factors in mind as well.

Have anyone else seen this? I'm on Comcast broadband, and download at about 3Mbps. Has anyone had any luck complaining to their provider about this? I'm thinking it would be pretty difficult, since my upload/download is 'as advertised' by the ISP.

Thanks for the help.

Hmm..since this is specific to times of day it would lead me to believe that perhaps Comcast is having congestion problems along the route from your location to Vonage. Perpahs something in your neighborhood is overloaded on the Comcast network.

This would explain why things get bad a night when you would expect high usage and better in the morning when usage would be muss less. You can try a tracert or use ping plotter to see exactly where along the path the slowdown is happening.
