Vonage Hi Sumner, whether here or the broadband forums you'll find hundreds of folks

Hi Sumner, whether here or the broadband forums you'll find hundreds of folks with issues with the SB5120. Vonageis well aware as they've been fielding headache calls for months since everyone initially blames them. I've been having the same problem since April - Looks like you're heading down the same road.
I bought a new Modem - a Linksys off of NewEgg for 42.99 after rebate/free shipping - it was here in one day - had it running only since last night BUT I have a happy connection again! No more phone drop outs - computer screaming across the internet again.
I don't want to diss the SB51xx series - it was a kickbutt modem BUT back in April something went flooey in the firmware they're dishing that made Voip, video conferencing, VPN and gaming near impossible. We'd ran that modem for years just fine - and 3 years with Vonage that were near flawless.... until April. Here's a copy of my last post - if it looks like a familiar story to you - Do yourself a favor and spare yourself the endless diagnostics and frustration - pick up a Linksys or a D-Link and see if it corrects your problem. If it doesn't - you simply bring it back and make Cox find the problem.

SB5120 modem, Docsys 1.1, 2.0
Vonage - motorola adapter

Problems since April.

Voip - I can here them but I drop out for 10 to 20 seconds at a time frequently throughout the call. Occasionally choppy. Problems occur every single call that I must make an immediate announcement for them to stay with me, I will drop out - be able to hear them, they just won't be able to hear me for spells.
Can not video conference anymore, broken audio, video freezes (vrmeetings/meetingplaza w smart bandwidth compression that even a dial up should fly and MSN). We do not do gaming.

Upload issue now showing on simply surfing net as usual, data has to be transmitted several times to go.

Ping tests and tracerts - heaps of time outs, packet loss, latency 100 - 300 ms
Voip tests - 59% - 82% QOS usually
Speed tests - sometimes good, sometimes under 300 on my UL.
Modem log - warnings, criticals, time outs - box loses signal.
Have taken Vonage adapter out of loop - no difference.
Have taken network down and run one pc through SB5120 - no difference.
Found hundreds of uers on this and broadband forums all with same complaint on SB5120: Voip UL issues, VPN, gaming, video conferencing problems.

Comcast response:
A unique and mysterious issue.
Phone support sees modem dropping out hundreds of times but techs to house say they don't know what they're talking about.
Replaced line pole to house.
Made me swap modem out at local Comcast store (replaced with same model - SB5120).
Complete denial of any issues whatsoever.
Mad at Fred who posted the Comcast engineers name and number who admitted via his own bench-testing that there WAS a problem with the 5120.

Best guess:
Firmware issue with SB51xx's - when we first plugged the new one in we were screaming and functional again - within a matter of hours (firmware updates) we were dead in the water again.

Waiting for my new Linksys modem to arrive, it has solved Fred and many others problems immediately.

Best wishes to all just starting out on this road, I've been at battle since April.
