Re: [Connectivity] New SB6120/6121 Firmware Released said by JJJohnson:Any hints about when Comcast might roll out the firmware update system-wide? I'm really getting fed up with the reboots of my SB6120.
The new firmware was pushed National.. |

Received this firmware for my SB6141 today when I unplugged the coax to replace old weather boots:
Jan 01 1970 00:00:14 6-Notice N/A Cable Modem Reboot from shell ;CM-MAC=20:e5:64:xx:yy:zz;CMTS-MAC=00:13:5f:05:49:53;CM-QOS=1.1;CM-VER=3.0;
Dec 04 2012 14:38:59 6-Notice E112.0 SW download Successful - Via Config file
Dec 04 2012 14:36:13 6-Notice E102.0 SW Download INIT - Via Config file d11_m_sb6141_speedtierextreme2_c01.cm
So now the help page shows this:
Model Name: SB6141
Vendor Name: Motorola
Firmware Name: SB_KOMODO-1.0.6.8-SCM01-NOSH
Boot Version: PSPU-Boot(25CLK) 1.0.12.18m3
Hardware Version: 7.0
Serial Number: 112233445500006677889901
Firmware Build Time: Aug 30 2012 15:35:46
Glad this has finally gone to general release, but can't wait for the SB6141 to be IPv6 certified on Comcast's list, since it shouldn't be much different than the SB6121 that already is (listed). Motorola's datasheet for it states that they share the same firmware. |

Kinda makes me wonder just what its all doing. |

| said by Mike Wolf:Kinda makes me wonder just what its all doing. Based on the release notes, 1068 was designed to allow modems that were in a constant reboot mode mode because of noise on one channel to lock that channel out and operate at a reduced capability. |

And the T4 is back on one of my channels today (1.0.6.8)...blah |

Did your modem reboot because of the T4? If not, then the 1.0.6.8 firmware is doing its job.

Not sure if it's worth mentioning, but I'm finding the sync time from a modem reboot has been erratic as well...sometimes the connection will come back fast other times the (reboot) lease time (~:20) on my router will keep resetting several times before the connection returns and quite often the T4 turns up on one of those prolonged re-syncs. Another reboot will clear that up but I'd think that's not the way it's supposed to be working, is it? |

Schaumburg, IL | If it's able to properly bond all upstream channels, it will reboot fast. If it's having trouble, it will hang at the ONLINE light blinking for a minute or so before it gives up and goes into partial mode. |

Is that more likely indicative of a problem with the system or the modem itself? |

Is that more likely indicative of a problem with the system or the modem itself? It's possibly a bug in the Motorola's because it almost always seems to be the middle channel that T4's, even if it's not the middle frequency. It's harder to tell if other modems have had similar issues with a disabled upstream channel.
I wonder what the tolerances for transmit frequency and 'leakage' into adjacent channels is. Maybe if some modems are a bit out of tolerance (or maybe the tolerances need to be tightened in the standards), they cause too much interference with adjacent channels. |

Make sure your modem model is setup correctly with Comcast. I have a 6121 and it was setup in Comcast's inventory as a 5100. Worked OK, channels bonded, but no new firmware. Modem had to be removed from inventory and be re-provisioned the next day (devices clear out of inventory after midnight). Got the new F/W at provisioning. Log into your account at Comcast.com / My Services to check your equipment inventory.
This is what worked for me, hopefully it will help others. |

12/19/12, 3:15am - My modem just updated itself to 1.0.6.8...

Hi, all.
I have this:
Model Name: SB6121
Vendor Name: Motorola
Firmware Name: SB_KOMODO-1.0.6.8-SCM01-NOSH
Boot Version: PSPU-Boot(25CLK) 1.0.12.18m3
Hardware Version: 5.0
Firmware Build Time: Aug 30 2012 15:35:46
After a recent reboot of modem and router (amped wireless R10000G) I noticed that the SB6121's link light changed from orange to blue. I checked the Signals page and sure enough all three US channels showed Success under Ranging Status.
Today I had to reboot the router, so I thought I'd reboot the modem. I normally do this by simply removing power, waiting at least 2+ minutes, then restoring power, first to the modem, letting it boot fully, and then to the router. After doing that the link light was back to orange, and the infamous middle US channel, which happens to be the middle frequency, shows the T4 TimeOut.
I tried the Reset All Defaults button, followed by the Restart Cable Modem button, but the T4 TimeOut persists. Also, Cable Modem Status is Offline, everything above it reads "Not started," and Initialize Baseline Privacy is Done. Not that I care about that page, as that's what it's always read.
My US channels are 4, 5 & 6, with 39 dBmV, 39 dBmV & 40 dBmV, respectively. These are steady. Also, I have a DS channel 5, but I suppose that's unrelated to the US channel 5.
The only log message since the last reboot and the assorted messages associated with that is this:
Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;CM-MAC=a4:7a:a4:6f:ca:a0;CMTS-MAC=00:01:5c:23:78:13;CM-QOS=1.1;CM-VER=3.0;
Priority = 3-Critical
Code = R04.0
My speeds are where they should be 50/10 Mbps.
Is there anything else I can try to restore all three US channels bonding? Don't really feel like calling Comcast atm, though I'm sure they've been wondering where I've been lately 
Thanks! |

| Personally when I get that middle channel T4 timeout I just restart the router and it generally works again, but sometimes it occurs again at the next restart but I'd only notice it if I'm on the signal page. I wish you good luck  |
|
| I tried another hard reboot of both, but the problem persists. If it's something on Comcast's side, maybe it will correct itself eventually. |
|
| Do hope it does clear up. I wonder if your neighbors are seeing the same issue. At least this issue doesn't keep you from having internet so that's a plus. |

For some reason, I've found doing a power-off reboot instead of rebooting from the menu seems to more reliably bond all channels. |

And that's normally what I do. I only recently read about the Restart button available from the web interface. I like to do both router and modem, but my router is now very slow to receive its WAN info from Comcast, so reboots take up to five minutes before PCs get Internet access back. I guess I'll try just a modem reboot, once the wife lets me |
