QoS - almost unusable

I have been using Vonage for almost five years and for the past fifteen months have been using Comcast in the ATL area.

Over the past two months my Vonage service has been the pits as it has become unusable more ofter then not from this location.

I am posting my Test Results for my 6-10 Mbit service.

I know - all that wait time (latency) is even causing me to go to Business depot to send faxes as the fax machine is unusable.

Have you contacted Comcast in your area to see if they can assist you?

What's the network configuration?
and
What are the test results with the computer directly plugged into the cable modem? (Do they differ)

I have spent hours on the phone with Vonage tech support. We have tried all variations with no change in service. The latest attempt is the replacement of the P2P to the VTA-VD - No change but I do like the extended configuration ability in the VTA-VD (D-LINK) as to the more restrictive configuration in the P2P (LINKSYS).

Configuration - Scientific Atlanta cable modem (Comcast) to Linksys (WRT54G v Cool

router from there the pc (port-1) set to 5Mb max and the VTA-VD (port-2) set to 2 Mb max (my service is 6Mb - 10Mb with push - WRT54 v8 is port forwarding to VTA-VD ports (10,000-20,000) also have rtp service set to (premium) in the event I am doing something else on the network, the VOIP gets priority.

We have tried all configurations even flashed the WRT54G v8 firmware with dd-WRT GNU firmware for QoS options which were not available on the WRT54G v8.

Have tried the P2P right after the Cable modem same issues.

Turned off all QoS - realizing it is only required when other activity is on the network no change.

The Comcast service has not been troublesome over the past 13 months but for the past two months it has been a real issue with QoS - I have contacted Comcast several times. The last correspondence with them advised me they would look into and respond by phone call in 24 hr but that was tree days ago.

I am moving soon and seriously wondering about my ISP options will be in a residential area and not apartments - I posted a survey with the hope of real feed back and helpful for those setting up an ISP account or changing ISP account.

who is "they?" Vonage or Comcast?

This is the 2nd post in the past 24 hours where there are claims that Comcast has corrected a problem in their network and calls now have good 2 way audio. If this is the case, it may have been a misconfiguration within the agnostic software being used to throttle bandwidth if being abused for extended periods of time on congested nodes.

I was contacted by the Executive Branch with in Comcast last week and was told they would look into my concerns and follow up with me in 24hr - A little late but I was contacted last night by the same person, obviously they have looked into the issue and restored my QoS for the time - Really Comcast has been great for 13 months out of 15 but for the past two months my Vonage service has been mostly unusable or very troublesome to use.

Comcast did not provide any feedback on the changes if any but something changed and "In my opinion" it was there efforts that resolved my unusable Vonage service.

Comcast will listen it just took some time.

Cheers
