Post subject: Dropped packets, choppy call madness
Hi Steve, I am experiencing the same symptoms It gets to the point where it freezes up my computer internet, it drops AIM and gives page load timeouts on Firefox. I had replaced the router this weekend with a Netgear 108. Seemed ok for a couple of minutes, then back to the old tricks. I replaced the Comcast cable modem today (wednesday). This time,. I got an hour out of it. Weekend before was maddening, I could get maybe 2 minutes of phone per hour with the calls dropping like flies. With the new router, the calls dont drop any more, but the quality is impossible.
I followed the instructions you gave to the other member in here. The results were VERY ugly, to say the least. I tested with the
Vonage
box in, then unplugged. The drop rate was 3.31with the Vonagte box attached, and went to 3.17 with the
Vonage
disconnected. The second results are posted below:

which looks like I am losing nearly 80% packets.
I will be going back to Comcast tomorrow. It might be a bad line in their neighborhood. Another thread mentioned it.
It seemed to come in when the hot weather jumped in, sdo it sounds like an outdoor source here.
Any suggestions or anything else I can do? The cable is 400 feet buried 3 feet deep to the roadway. At my house, it comes out of a pipe and into a connector, then into the house, maybe 1 foot of connection.

I disconnected the
Vonage
box and ran the tests again - results below.
My ISP has outsourced its call centre abd the service is now terrible. Can you tell me what exactly I should tell them to be looking for please?
Thanks !!

Hi, Tony. Yes, your packet losses are just awful, but in one direction only. You should also check your upload/download speeds and see what's going on. I suspect your download speed is fine and upload is bad. Since you ran the test with the computer plugged directly into the modem (Right? If not, take the Netgear out and re-check to be absolutely sure.), the problem is definitely with your ISP. I include your modem as part of the ISP's domain. Jack 'em up.

Therein lies the problem. I just looked back to the beginning of the thread and see that you have some sort of Yahoo service (?). Your download speed, by the way, is nowhere near what you say it should be. Is there a typo in there?
Many ISPs aren't very cooperative when it comes to
Voip
service since you aren't paying them specifically for that. If you have any symptoms associated with their basic service, such as poor speed, a lousy television picture (if it's cable), and so forth, you may want to focus on that. If not, then just tell them what you've told us and cite the testyourvoip.com packet loss and discard results.

Nope,. I left in the router. It was a brand new one I purchased on Sunday.
Since it is burst loss of packets, I am suspecting noise noise. Not constant, but going on. That is what I had with my telephone line last time.
I was going to report to the Comcast office after work, but a freeway accident made that impossible. What I did was there is a feed through outside the house, 2 F screw connectors. I am suspecting since I water the plants in that area, it may have corroded inside. The metal did look dull. Inside was shinier. I unscrewed, hit with WD40 and a wire brush. It is working right now, so fingers are crossed.
I will try out the computer direct to modem on monday if I still get it tonight. I tried a test early this morning, TestMyVoip web page couldnt even come up and Pingtrotter claimed it couldnt find the domain.
Weekend will have me gone to a trade show, mucho movie stars I am working with.
When the going is good, all is great but I really am suspecting intermittant line noise. Am hoping that the outdoor connector was the root cause....
