Ping test - what is acceptable?

Posts: 9 · New Forum Member Joined: Nov 23, 2004 Posts: 9

Every couple of weeks my Vonage service goes to the pits. People on the other end say I am breaking up. The testyourvoip varies from great to terrible. I am pretty convinced it is a Comast problem and am looking for proof. I have pinged their site quite a bit. Usuall get returns in under 100MS, but sometimes get a lost packet (no return within 4000ms).

So............... my question is. How often should this happen (I know never!), but I wonder what Comcast would consider within reason.

Thanks

I think ping times of approx. 150ms are considered good for voip; so 100 is great!

However, when you do experience larger ping times, I would suggesst to call Comcast immediately, and tell them that you were experiencing slow connections, and so you pinged a host and found that the responses were slow.

Also, PCPITSTOP.com is a good site to test upload speeds when you experience choppy sounds on other end.

Here is another good site for testing your Download & upload speeds, just choose server that is closest to your location, from list of servers on left of this page and wait till test is completed for both results..takes only a minute or less to test...usually

as far as calling Comcast and telling them that you believe that their connection is slow...dont waste your time, they never admit to it, and try to blame your equipment on the problem, not theirs...usually slow downs with comcast in my area at least will happen on ocassion, but they end up getting fixed fairly quickly, unless there is a big "node" problem in their equipment, then you may not have any connection at all for awhile..but as far as comcast taking any blame...they dont...I think their CS reads Que cards for answering people's problems when you call for support
