Sh*tty modem or out of date firmware

*Sigh*, another damn problem with this modem. I'm getting constant

Cable Modem Reboot due to T4 timeout ;CM-MAC=3c:75:4a:6a:a2:ac;CMTS-MAC=00:00:00:00:00:00;CM-QOS=1.1;CM-VER=3.0;

Model Name: SB6120
Vendor Name: Motorola
Firmware Name: SB_KOMODO-1.0.6.1-SCM00-NOSH
Boot Version: PSPU-Boot 1.0.0.4m1
Hardware Version: 3.0
Serial Number: (**I blanked this line**)
Firmware Build Time: May 12 2011 15:15:14

God I'm getting tired out this nonsense.

Can I download the latest firmware, or do I have to pester vmedia to push?

Vmedia will sell you a DCM476 for $59.95, why not just buy the new modem? I don't get this loyalty to Motorola modems. Sure, back when DOCSIS 2.0 was the standard they were the go to guys with the SB5100 series of modems but since the wide adoption of DOCSIS 3.0 the current leader in modems has obviously become RCA/Thompson/Technicolor with their DCM47x series. $59.95 for the new standard in D3 modems, which is also 8/4 vs. 4/4 channels, doesn't seem that bad to me. For the sake of $60 I certainly wouldn't put up with constant problems with my internet connection. When I pay 10x that amount, or more, per year for my internet service it just doesn't make sense to put up with constant problems for a 10% investment in stability (and speed with the extra 4 downstream channels).

So, if you can't tell, my vote is for sh*tty modem. Drop $60, do yourself a favour.

Then lets start a petition to have the TPIA providers to use their "free" yearly test on the SB6141 which has the 8 channels.

My SB5100 has gone strong for at least 6 or 7yrs, I question whether the RCA one will too (and not from a technological perspective)

No, I didn't. Honest... I ran out of gas. I... I had a flat tire. I didn't have enough money for cab fare. My tux didn't come back from the cleaners. An old friend came in from out of town. Someone stole my car. There was an earthquake.......

I might have to. I just got the modem though a couple of weeks back when the service was installed on July 18th. Perhaps GeorgeBurger can do a swap for me?

Looks like the signal is good.

You have the firmware version that Rogers has certified for the SB6120/SB6121, there's no need for a upgrade to be pushed.

Cable modems are not firmware upgradable by end users and only the cable company controlling the coax can push the upgrade so that would be Rogers. And they have stopped pushing firmware upgrades for TPIA/ATPIA customers for a long while now.

Yeah, I noticed the SB_KOMODO-1.0.6.1-SCM00-NOSH firmware as well and I know it's on the list of "approved" by Rogers. So, I'm guessing it's the modem. I've dropped a note to GB, and I hope I can swap out this modem for the DCM476 then.

Just a quick glance at the logs, and I've counted 17 drops in 24 hours.

T4 Timeout ( Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received )

Details: The cable modem did not received a station maintenance opportunity in which to transmit a Ranging Request (RNG-REQ) message within the T4 timeout period (30 to 35 seconds). The cable modem is resetting its cable interface and restarting the registration process. Typically, this indicates an occasional, temporary loss of service, but if the problem persists, check for possible service outages or maintenance activity on this particular headend system.

In other words, it's a cable system problem

I told you in the other thread about SB612x's that they have T3 and T4 timeout bug on Rogers.

1.0.6.1 is the only firmware Rogers "will allow', even though that version hasn't cleared up completely the sync issues.

Rogers has basically retired support for this modem. No further support. If you choose to use it you may, but beyond that they don't care about them at all. And will not qualify newer firmware patches, or push them. If you have issues, they will just blame the modem. The modem is technically a good one, but not so good firmware. With lake of newer firmwares and bug management, it has fallen behind the DCM's.

As other said, just buy a 8x4 RCA for 59$ well worth it. My SB612x had errors flooding the logs, my DCM has a basically empty log. lol I have network issues, but non of them appear to be on the modems end. Only routing and capacity issues at ISP's.

Now you have played with the Motorola SB hope ya now understand why I was previously attempting to let ya know that it's not worth it. And to just go with a DCM475/6.

It's appreciated. I noticed that it's no longer available at the vmedia site. Not sure what to say about that since less than a month has passed.

It is a perfectly good modem, I have over 100-200 customers using them without significant issue. Even though your signals look great, I think you'll find you have a line issue.

There is a chance your specific modem (or more likely the power adapter) has an issue. Talk to the provider about replacing it, or I could maybe help you diagnose that for a small fee.

Thanks for the feedback Teddy. I had a Sb5100 in place for 10 years. Rock solid. Never an issue going from provider to provider. Rogers, Acanac, Start.ca, and last CIA3Web. And the line was checked by a certified Rogers tech for SNR on the install date of July 18th. I'm going to err on the side that it's probably not a line issue. I have logs full of these events, and never saw the issue with SB5100.

Gotta say "Thank you" shwatkin. I received the DCM476 the other day, but had to wait until today for Rogers>Vmedia to get it on-line.

What a HUGE difference.

I was receiving about 5 to 10 errors - Timeouts > reboot on the SB6120 per hour. Last 2 hours (since 8 a.m.) with the DCM476. Zero timeouts. Zero errors. Clear log. What a massive difference.

I'm sure the SB6120 is a good modem. I just happened to get a defective one, or there might be a compatibility problem using them with Rogers backbone. I don't care. I'm a happy camper to have a working modem now, and it appears that Vmedia has ironed out a lot of the wrinkles with speed and stability.

Thanks again.

And thank you GeorgeBurger.

No problem. I'm glad the fix was as simple as a new modem for you.

I'm surprised that was the problem ... but I'm glad it is fixed for you.

It would seem yours is just a DOA modem which is pretty rare.
