What's funny is that I'm still having that issue with that Cable Modem Status displaying "OFFLINE" even when it actually isn't and I'm able to browse the web.

This is a known bug in 1.0.6.x. You can reboot the cable modem (do not reset to factory defaults) and the issue should go away. It usually happens if one of your upstream channels is in Other or T4 Timeout state, or possibly was in the past, but I've also seen it reported when all upstream channels are negotiated fine. I can provide historic reference posts/details if need be.

Neither the MIMO nor the TLV-11 log entries indicate any actual problem.

I can't explain the technical details of the MIMO message but it's harmless.

The TLV-11 message indicates that there's just some SNMP MIB OID that is trying to be looked up (probably by the CMTS, or by Comcast's own systems) that doesn't exist on this firmware (but may exist in older ones). The OID isn't provided so I can't look it up in a MIB tree to find out what it is. I started seeing this with 1.0.6.6 or thereabouts, and like the MIMO message, it's harmless.

I should note to folks reading this thread I've been testing 1.0.6.8 for Comcast since 2012/09/25 and I have not seen any problems. If anything it's better -- see the 2nd bullet item in the 1.0.6.8 changelog (I can confirm this was a problem in 1.0.6.6 which is now fixed -- if it happens, modem goes into TCS Partial Service mode but continues to operate fine, just with one missing upstream bonded channel).

The MIO and TLV messages are normal at this point. They do not indicate anything is wrong with your Internet connection (despite what you might find on Google).

The MIMO -MDD IP Mode Override
is just telling the modem a temporary/extra/contrary instruction from how the MDD - MAC domain desprictor, described the plant capablities So if the MDD said this plant supports a IPv6 wan side interface, this MIMO could be saying "don't use the IPv6 for now on this model modem" or some other feature should be added or disabled.
This is a normal and planned for ability for D3, not a defect.

I would like to add one more comment to this, this doesn't have anything to do with what the CPE is doing. This is only on the DOCSIS side of the modem. Alot of people are getting the DOCSIS side MIMO and the CPE side support confused.

Got the update here on my SB6120.

Speeds are solid as ever.

Got it after a reset/reboot from the config page.

I always wait to power cycle for something like this until after you do it and I don't hear about any downside from you.

Did that. I wasn't having any severe problems before the upgrade, but I was consistently having tediously slow pageloads. I had been trying for awhile to troubleshoot on my end with no improvement. Signals weren't perfect but well within range, so I didn't see it as a Comcast issue.

After the powercycle, I did get the upgrade. My signals were nearly perfect once again and the page load issues are gone. So far, so good, anyway with nothing else changed here.

I have no idea if this is related or if it is just one of those cases where a powercycle would have fixed the problem without the upgrade.

I can assure you it's 100% unrelated. Your signal/power level issues are separate. Chances are the reboot of the modem resulted in negotiating different channel frequencies, some of which (for you) might have better levels than others.

ChangeLog for the firmware is here, and you can clearly see there's nothing going on that would impact signal/power level. There are some things that might impact performance but only in already degraded situations: »Re: [Connectivity] New SB6120/6121 Firmware Released

I actually posted that mostly to poke at my "almost" neighbor, tshirt.

Thanks for the reply, though. Hindsight told me I probably should be quicker to powercycle when I run into issues like that instead of futzing with browser configuration which had always been fine before and your post confirms that.

Edit: I really didn't think my signal levels had anything to do with slow page loads.

In my experience power level doesn't, but SNR can. If SNR gets too bad, the modem has to retransmit frames back to the CMTS (or vice-versa) which causes slowdowns. There's actual proof of this happening, because it's something I dealt with for many weeks (the official Comcast Forum thread is more indicative of the behaviour -- look closely at the mtr/traceroutes).

Good to know, SNR on all four downstream channels was 36-37 and still is. It was downstream power that improved after the upgrade/powercycle.

Re: Firmware update. (strange effects)

One of the stranger effects of the new firmware version. I'm paying for 22/5 and I am getting the speeds below (speedtest pointed to the Atlanta server)

Re: Firmware update.

Actually, I don't think it mattered, I got a forced powercycle last night, with no apparent problems, so I think they are working through area by area until everyone has it

The effect I'm hoping it solves is at the DHCP renew switching to only the first channel(only that channel acrews codewords) for a while (2 hours to a couple days) before all channels begin working again.
I believe this is part of the cause of slowedpageloads/"page not found" (which loads quickly if refreshed) but now I need it to stay active(no reboots or powercycles) for at least 2 DHCP renews to prove it.

I did find under the preivous firmware a powercycle temporarily improved it, and the problem did not appear to be signals or SNR related (always very good here)
Anyway CC must have found enough advantage to having everyone on 1.0.6.8 to push it, in spite of a few remaining issues
maybe in 2 more years...

That may not be due to the new Motorola firmware itself, but with the particular .cm "config file" that was downloaded to your modem during the update process.

I'll admit I do the same thing too - why not let other "early adopters" try it out first and see if there any issues.

Been running the new 1.0.6.8 version on my SB6121 for 36 hours now, and everything is still working fine for me (not that I had any issues running the previous version, though).

In the past, I've had issues where a certain combination of downstream channels would cause issues trying to upload to some computers. It mainly affected some servers through my work VPN. When I did a Quality test at VisualWare, there were tons of retransmit and other issues. Rebooting to get a different set of downstream channels fixed it.

Really just meant power and SNR readings are centered in the good range and consistantly stable.
Someone with unstable or borderline power might need to consider those as a possible causes of dropouts, reboots or packet loss.
