Recommended Tests

I have Comcast Cable for my isp and I have been very happy with it.  I recently started using vonage broadband for my home phone service.  I've had nothing but problems with them.  So far they've sent me 2 differant routers that don't work.  The INTERNET doesn't work on one, and the phone doesn't work with the other.  I went to Best Buy and purchased another one that kinda works.  I decided to buy the third one because Vanage only gives out wired routers and I was having to use another router for my wireless connections.  I figured everything would work better with just one router.  Well the internet seems to work faster but i just can't get the phone to work right.  When i call vonage they tell me it's the isp's fault.  They said it's not fast enough.  Comcast had a service tech. come out and test the line.  He checked the line coming out of the modem and said he has never seen such a strong signal.  Now i play the run around game.  I keep calling vonage and they have me test my connection at testmy.net.  I get a download connection of 525 Kbps. downloaded at 64kB/s.  My upload connection is 107Kbps uploaded at 13kB/s.  Comcast says my connection is excellent and blames vonage.  Vonage says my signal strength is bad and blames Comcast.  Someone help me please!  WHO DO I YELL AT!   

Comcast got you!!! any speed below I think 2MEGS A SECOND sucks and is to low when Comcast is advertising 6 meg in some locations. You need to call them back up and find out why its soo low. Right now I think the blame for the phone not working is Comcast

Thank You for your help.  I just wanted to let you know that I ran the tests again.  once straight from the cable modem.  Those results were ( Download connection - 3647Kbps. downloaded at 445kB/s.  Upload Connection 291Kbps  uploaded at 36kB/s)  then I ran the tests after the vonage router.  the results were very differant.  after the router (Download Connection 525Kbps  downloaded at 64Kbps.  Upload connection107Kbps uploaded at 13kB/s.)  Thease results make me think it's proubobly the vonage router.  it's jusy hard for me to understand because this is the third router i've tryed.  I wish there was a way to speed up the connection through the router.   Thank You 

I too spent weeks with marginal vonage service. Vonage techs were able to tune my system but still conversations were choppy. The fix to my problem turned out not to be vonage OR Comcast but my cable modem. Turns out I had an older 3com modem and it did not have the speed capability now available with Comcast. Replaced with a LinkSys modem because I like the brand and it was on sale. The Motorola Surfboard 5100 was recommended by vonage and Comcast techs. Installed new modem and everything is working fine now.

Based on your upload/download speeds I suspect you may have same problem.

I don't know much about vonage, but i have att call vantage (also voip) and havn't had any problems with bandwidth. You might want to try that.

I have vonage worked for 3 months now cannot get it to work,
I have Comcast as well, but I cannot understand why it worked then all of a sudden just stopped, makes no sense to me, any suggestions,
everything on the router lights up but the phone???
worked well while it lasted.

i have vonage and its great. the only thing that is creating a problem is upload speeds. when using the net while on the phone, its ok but when it comes to downloading while on the phone, thats an issue. im sure if i had the 768kb upload speed, it would be much better.

I have used vonage over my Comcast cable connection since July of 2005 without a problem, until last week.

the rumor on the vonage-forum is, since Comcast is now rolling out their own telephone service, they are blocking all vonage and other voip networks.  I do not know if it is true or not, but I have had spotty performance every since Friday, and all other internet access is fine.  testmyvoip.net works great, and tracert.exe works well everywhere except to vonage.  I can access the vonage web page normally only if I leave the Comcast system, i.e. go to a coffee house with wifi.  pings to the vonage web site are dropped, and log in can take minutes instead of seconds.  vonage is posting on their web site that there are technical problems due to a Comcast upgrade.  I do not know if the problem is a vonage or Comcast problem,  but i will b e cancelling both of them soon if they don't get it straightened out.
