I have had terrible service since Comcast did a major up grade in service in S. Fla. last week.

Have you run the forum Voip test? If the results support your implication that Comcast is at fault, then get with them and make them fix it.

I also had a major problem when Comcast took over Adelphia. Found out that it was an issue with my D-Link DCM 202 cable modem as it seems like Comcast only supports DOCSIS 1.1 and not 2.0

I am not very tecnical but I know that my phone quality has plumeted since Comcast started the takeover process. There are horrible echos and breaks in the call.

Test without being on the phone:
---------------------
Download speed: 3835480 bps
Upload speed: 361912 bps
Quality of service: 84 % - This is more often as high as 92%
Download test type: socket
Upload test type: socket
Maximum download pause: 52 ms
Average download pause: 4 ms
Minimum round trip time to server: 30 ms
Average round trip time to server: 91 ms

Voip test statistics
--------------------
Jitter: you --> server: 7.3 ms
Jitter: server --> you: 9.6 ms
Packet loss: you --> server: 0.0 %
Packet loss: server --> you: 0.0 %
Packet discards: 0.0 %
Packets out of order: 0.0 %
Number of supported Voip lines: 6
Estimated MOS score: 3.9

Based on my test, can Comcast be held responsible for the lousy quality? Also, I read somewhere something about changing the bandwidth. Does that mean go into the Vonage website and adjust the bandwidth scale? If so, to what?

Thank you

I also had major problems (choppiness, dropped calls) when Comcast took over for Suscom in York, PA last year. After a month or two, things improved and got back to normal. (Knock on wood)
