Packet loss with Cox, WRTP54G, outbound problems...

Posts: 4 · New Forum Member Joined: Aug 06, 2005 Posts: 4

I just got off the phone with Vonage and after about an hour on the phone and 5 power cyclings of my WRTP54G I still have trouble making callings to some area codes. The Vonage rep said he was showing 85% packet loss and that 40% would be ok, but that I needed to call my ISP and get that fixed. So I called Cox and they don't know anything about it, but said they'd send a tech but they would probably have to charge. So I'm trying to figure out who's to blame here, Vonage or Cox. I'm ok calling to some numbers, but not others, and all incoming calls are fine. I've heard people I'm calling say they can hear me, but I never even hear so much as one ring on my end when I'm calling out. I've got a Siemens AMBIT 60678EU modem. Any ideas on what could be causing this?

any idea why the permanent first post on this forum is titled "What to post when having technical trouble with Vonage...."?

Ok, so I missed a few...

I'm in San Diego, and have Cox cable at about 3-4mbit down/512kb up. The connection runs from modem->router->PC (wired). I've seen my testyourip.com rating to Boston go anywhere from 3.2-4.4, so this is just one of the results...

what firmware do you have on the wrtp? I'm not highly impressed with the testyourvoip results, especially if they fluctuate as much as you say. I would probably run pingplotter.com over a period of time and show the results (assuming they're less than stellar) to cox and/or post them here.

I am having exactly the same problem since Monday night. coincidentally exactly when Vonage 's entire network got shut down.. I still get fast busy.. cant dial some area codes and choppy audio.. they tell me its my network.. I had my cable co come in today and check the signal strength.. and I have 4Mps down.. I have reset my adaptors till the cows home. nothing.. Im bailing ship..I cant deal with this finger pointing anymore..

I have updated the firmware to 1.00.37.

I ran PingPlotter and came out with over 95% packet loss at the 2nd hop (,just after the router, something like 10.8.153.17) with both the router and a direct connection from the modem to the computer. This was with a trace to the primary DNS Cox uses (and google.com).
