PostPosted: Wed Dec 17, 2008 11:26 am    Post subject: Problems with Comcast / Ambit U10C018 Modem Reply with quote Back to top

Location: Richmond, TX (just west of Houston)

ISP name and type: both ATT DSL and Comcast cable modem

Upload and download speeds: DSL 6 / 1.5, Cable, possibly 10 / 2.5, but with “PowerBoost”, who knows?

DSL Modem: Siemens SpeedStreem 4100, Cable Modem: Ambit U10C018

I have four Vonage adapters, (2) Motorola VT2542-VD, LinksysWRTP54G and D-Link VWR-VD.

Network setup is Modems > Linksys RV082 Router > Vonage Phone adapters
The RV082 does automatic fail-over in case of an Internet outage. The Vonage devices are plugged into ports that have QOS priority and the rest of the LAN plugs into a router port with lower priority.

The issue is related to using Vonage service when running on Comcast. It may help to know that until a few weeks ago, everything was working perfectly. I typically run with DSL as the primary ISP and Cable as the secondary simply because the Vonage performance is better on DSL. With that said, the cable modem has always worked reasonably well…just not as well as DSL. A few weeks ago we had a DSL outage so the RV082 tried to switch to cable. After some time and a service call, the diagnosis was that the modem had failed. The guy replaced the Toshiba modem with the Ambit modem, and everything seemed good. In fact, speed tests at speakeasy.net were the fastest that I have ever seen at this location. It was so fast that I thought we might try to run with cable as the primary ISP for a while and see how it went.

In short, it did not go well. The first problem I noticed was that incoming calls on the VT2542-VD devices had a problem where no audio could be heard on our end. I am not clear on whether the caller could hear us or not. The second problem had to with outgoing calls via the same Vonage device – there was a dial tone, and we could dial, but it would never ring. We could place outgoing calls via the other Vonage devices with no problems, although we did notice some cases where incoming callers could not hear us answering the phone.

Obviously, the new cable modem is suspect, but that fact that some of the Vonage devices work better than others seems to suggest that Vonage is playing a part in the problem as well.

Here are the results of Voip tests for both ISPs:

DSL:

Speed test statistics

Packet loss: server --> you: 0.0 %
Packet discards: 0.0 %
Packets out of order: 0.0 %
Number of supported Voip lines: 34
Estimated MOS score: 4.1


As you can see, the QOS on DSL is better, which has always been the case, although the cable modem is quite a bit faster.

I guess my question is, has anyone else experienced similar problems after a modem replacement, and if so, how did you resolve the problem? Calling either Vonage or Comcast is just about equally frustrating. Vonage always wants me to take my entire system apart…even though our phone call would be terminated by doing so. Vonage does have some good support people at the top level, but I have found it to be VERY difficult to actually speak with those people. I am not sure if Comcast has any good support people or not, but if they do, I have never spoken to one.

Any ideas on this?

Thanks,
-Mark

Seems to make no sense . . . but I would disconnect the cable modem from the Linksys (isolate it) and try connecting ONE Vonage adapter to the cable modem and see if the problem exists.

Add a simple router to the cable modem and add a second Vonage adapter, and so on.

This may point to a throttling issue in the cable modem or worse, with the cable company.

On that particular vpn 8 port router, have you configured it to give RTP (UDP ports 10000-20000) packets High Priority? Did notice that you set QOS on the ports.

Mark,

I would strongly recommend dumping that cable modem and grab a Motorola Surfboard 5100 or above from eBay, Best Buy, etc. They're just reliable modems. That may solve the problem right there. Comcast will allow you to do a MAC swap from your current modem to the new one. This will get you up and going. If you're renting the old one, you can turn it in and save money per month.

Also, I know that your whole point of having both connections is for redundancy but I have a different idea. It doesn't sound like you're bridging the ISP connections for maximum throughput, so why not break apart the connections? Put the AT&T DSL on its own router and run Vonage solely on that connection. Run your office internet through the cable modem and a standard router. If one fails, your swapping is more manual but it is still there and you have ultimate QoS with dual ISP dedicated to Voip and Internet. It is similar to offices having separate voice T1's and data T1's.

My $.02

Mark,

I have dealt with dual WAN routers on many occasions so I am not sure how you have it set up working now and how it was working the entire time before. Are you strictly using on the cable connection as the preferred and will only fail over to the DSL in the event the cable WAN interface loses connectivity? Or do both interfaces provide simultaneous connectivity upon demand.


The reason I ask is because in every case I have seen, the SIP signaling was using one of the interfaces or actually hopping between both. The RTP traffic was then using the other. Why this is bad is because the Proxy your registering with with signal the Media Relay to listen for RTP traffic on the source IP your SIP registration is based upon. However, depending upon your dual WAN setup, if the RTP packets leave your network on the other connection, the Media Relay will ignore these packet because the traffic is coming from an unknown IP.

This would explain it yet I am not sure since this would be sporadic and occur on all the devices.

I do recommend disconnecting the DSL connection for testing and only run on the cable to verify whether or not your router is sending some traffic out one interface while sending other traffic out of the other. If this turns out to be the case, you would need to figure out how to configure all UDP traffic to use only one of the WAN interfaces.

Sorry for the long delay...apparently the forum is not sending activity notifications for some reason. Anyway, I have been stuck on DSL for a while, but this issue came up again today, so I just thought I would check my post, and here you guys are, responding without me even realizing it!

Ed56, if I connect the Vonage device directly to the cable modem, it works a bit better, but still not perfect, so while the router is adding some drama, I do not believe that it is the actual source of the problem…and keep in mind that this is the same router that works perfectly via DSL. Honestly, I wouldn’t doubt if it had something to do with throttling, since the new modem seems so much faster on speed tests, but is rather “bursty”

Slyster, I have to admit that I don’t know how to configure the RV082 to give high priority to UDP packets, nor does it support QOS so far as I know, although I have given higher priority to the Vonage ports, and that seems to work well.

Ksig, I am particularly interested in your reply because it seems to echo what I have been thinking – that the problem is related to the new cable modem. Do you happen to know if the 5100 supports these new speed features? Then again, it may be that those features are exactly the reason for the Vonage troubles…(?).

As to segmenting phones and Internet, I’ve thought of that, but that’s not really what I want. I want an automated switch-over so that if I’m out of the office, people can keep working without losing much time. I also thought of using the bandwidth management feature, as it really does speed up web response when multiple users are working at the same time, but unfortunately, Vonage has never been able to survive with that feature enabled, so I just settle for fail-over mode.

VonTechMgr, the router can be configured either way that you describe, but since the Vonage devices do not like to be switched, I have had to settle for fail-over mode. At present, I have DSL as primary, because cable works so very badly with Vonage, but the cable tests quite a bit faster, so I would probably make cable the primary if I could get Vonage to play well with the cable modem. What you are describing would pretty well explain what happens when I let the router allocate bandwidth…and needless to say, it doesn’t work at all.

If I connect the Vonage box directly to the cable modem, that works better, but still not reliable, so again, I know the router is a factor, but it seems to be related more to the cable modem. And yet, the cable modem sends data at an amazing rate…approaching 20 Mbps at times with 2 Mbps up…I don’t know if those numbers are real, but it sure does seem fast…wish I could use it for a while and see if it feels as much faster as the speed tests seem to indicate.


Thanks all,
-Mark

Mark,

Don't be focused on your speed. Just because the cable connection provides you with more bandwidth, does not mean that it is clean. You have to remember this connection is shared over the local node with your neighbors and become quite noisy at times. Many people get consumed with too little bandwidth causing audio issues. This is not the case for most people. It only becomes the issue when your utilizing your bandwidth for other things like P2p or gaming while talking on he phone

This is why the DSL is slower because it is considered to be a dedicated line to you which means it will have less bandwidth for the most part but is usually a cleaner connection.

When testing bandwidth, it is moving packets between you and a test server. You could have a solid connect between these 2 points but it does not means that you have a clean connection without packet loss, latency, and jitter between you and Vonage especially during peak hours.

Sure, I understand what you are saying. And DSL has always has worked better for me, with Vonage, than cable. Still, the main reason that I have two internet service providers is to give me some redundancy, so in order for that to make sense, Vonage has to be able to work with the cable modem.

If the voice quality suffers a little bit when on cable, I can handle that, so long as it works reasonably well. I ran Vonage on cable for a few years before I got the DSL line, so I am well familiar with the level of quality that should be possible, and it's "okay". DSL is better, but cable was still acceptable...at least until the modem change.

I originally bought DSL as a backup to cable. I figured it would be too slow to replace cable, but I just wanted something to use when the cable went down...which actually happened fairly often.

After I survived a few cable outages on DSL, I gained a new respect for DSL...so much so that I now use it as my primary Internet service. Even so, the DSL service does fail, even if rarely, so I still need Vonage to work on cable...even if I never do go back to cable as my primary ISP.

I have to tell you though, the speed for downloads is compelling...it's easily 50 percent faster than my 5 Mbps DSL, even ignoring the speed burst (or whatever they call it). Too bad Vonage can't find a way to work perfectly in that environment, since so many people have cable service.

While I agree the Ambit may be part of the issue since it is on our list of hardware that causes possible issues, if you sniff around the forums, many other Comcast customers starting experiencing audio issues just in the past 2 - 3 months.

As for the Motorola SB-5100, it is solid. I use it with my Optimum Online boost package which provides me near the 30Mb / 5Mb I am offered. For the most part I get about 27Mb down and always get 5Mb up.

The modem itself, like most other DOCSIS 2.0 designs is good for up to 38Mb down and about 30Mb up.

Even if you swap out the modem for a 5100, there is no guarantee this will correct the problem as I fear it is with the Comcast packet shaping, rate limiting, throttle enhancements they have made that I feel is misconfigured.

Well…I don’t know what the statistics are, but there must be an awful lot of people who use Vonage (successfully) with a cable modem. My non-tech neighbor seems to have no trouble at all with either service. So it doesn’t seem all that unreasonable to think that I should be able to make it work well enough to serve as a backup to DSL.

(sigh) I guess I'll have to call Comcast. I don't mind buying the SB5100 for $50, but then I would still have to rely on Comcast to make it work. If I'm going to do that, maybe it makes just as much sense to just ask them to just make the service work for me. I certainly do not look forward to calling those guys.
