Vonage has been great since I got it until the past few days. The call quality is horrible all of a sudden. We have the V-Portal phone adapter with Comcast High Speed Internet. My Internet speed is great. I'm on the 20 Mbps plan and could go on and on about that.
Any ideas?
Thanks!! |

Can you post the information in the sticky message "What to post when having technical trouble with Vonage...." |

Sorry about that.
1. New Jersey 2. Comcast Cable 3. Blast! Speed is fast enough for Vonage at 20 Mbps down and at least 3 Mbps up. 4. Netgear Wireless G 5. V-Portal Phone Adapter 6. Modem >> Wireless Router >> Vonage Phone Adapter (Plugged directly into router) 7. Choppy audio... 8. Speed test statistics --------------------- Download speed: 1239160 bps Upload speed: 2626952 bps Quality of service: 27 % Download test type: socket Upload test type: socket Maximum download pause: 415 ms Average download pause: 24 ms Minimum round trip time to server: 63 ms Average round trip time to server: 113 ms
Voip test statistics -------------------- Jitter: you --> server: 7.1 ms Jitter: server --> you: 8.3 ms Packet loss: you --> server: 0.1 % Packet loss: server --> you: 0.0 % Packet discards: 0.0 % Packets out of order: 0.0 % Number of supported Voip lines: 21 Estimated MOS score: 3.8
I just did a speedtest on www.speedtest.net and noticed that my download speed is less than 5 Mbps download. It is usually 20-25 Mbps. Maybe they are having problems or I reached my bandwidth limit. Still, 5 Mbps should be good enough. How do the other technical specs. look to you? The packet loss, jitter, and all that? Is that good enough?
I might need to give Comcast a call...
Thanks! |

This is after calling Comcast and getting a signal sent out to my modem:
Speed test statistics --------------------- Download speed: 3895152 bps Upload speed: 2798416 bps Quality of service: 73 % Download test type: socket Upload test type: socket Maximum download pause: 505 ms Average download pause: 7 ms Minimum round trip time to server: 59 ms Average round trip time to server: 99 ms
Voip test statistics -------------------- Jitter: you --> server: 4.5 ms Jitter: server --> you: 4.6 ms Packet loss: you --> server: 0.0 % Packet loss: server --> you: 0.2 % Packet discards: 0.0 % Packets out of order: 0.0 % Number of supported Voip lines: 47 Estimated MOS score: 3.9
Is that better? |

The numbers got a little better but much. You might want to perform some other speed tests but it looks like the download speed is still much lower than you should be getting. The max pause and average round trip time (relative to the minimum time) is still much too high. |

This is with my laptop connected to the router with an Ethernet cable.
Speed test statistics --------------------- Download speed: 7405480 bps Upload speed: 2775144 bps Quality of service: 82 % Download test type: socket Upload test type: socket Maximum download pause: 62 ms Average download pause: 5 ms Minimum round trip time to server: 56 ms Average round trip time to server: 100 ms
Voip test statistics -------------------- Jitter: you --> server: 0.7 ms Jitter: server --> you: 0.5 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: 47 Estimated MOS score: 4.3
My speed is between 20 and 28 Mbps down according to www.speedtest.net . The other two tests I gave you was when I was outside. My speed according to Speedtest was about 10 Mbps outside a few minutes ago.
So is this speed test with my laptop connected directly better than the other one? |

The speed is better (the wireless verses non-wireless would explain that) however the min time verses the average time is still a little high. That suggests that the max time (or high variances) are throwing the average.
Can you run a ping and traceroute to these IP addresses from your computer and post the results: 69.59.248.70, 69.59.241.11, 69.59.239.70.
In Windows, go to the command prompt (usually Start > Accessories > Command Prompt) and type:
ping -n 100 <ip address>
tracert <ip address> |

ping -n 100 <ip address>
tracert <ip address> |
Average ms for ping:
14 115 94
That is in the order of the IPs you gave me. I only did the ping not the ping -n 100.
I didn't do the tracert either. I don't have the time to do it right now.
What can you get from the information I just gave you? |

Could the possibility of Comcast's Network Manager, which is being checked out by the FCC, could be the problem? there are several articles on the web about Comcast using a new manager on their network that will cause audio issues with Voip customers that do not have Comcast phone service. |

The phones seem to be working fine now. 
If Comcast is doing something to cause issues with Voip other than their own I think Vonage should sue them. Then Vonage can put that money into improving their products and services. (Not that they need improvement)
I'm paying for Internet. I should be able to do what I want with it. If I want to have IPTV (Not really out yet...) or use Voip without other Comcast services I should be able to. I shouldn't have problems because Comcast wants me to use their company for everything. |
