| Internet goes out every time firmware update fails. HELP!
i have comcast HSI using motorola sb5101 modem. this is what shows up when i log into the modem:
then it just repeats over and over. when i look at the time they directly coincide with time that my internet goes out. to fix, i have to power cycle everything. i have had the same problem with 5101 and the 5100. is this fixable or do i have to pay comcast 6 more dollars a month to lease one of their modems? |

| The problem is that your SB5101 modem has a config file for an SB5100. The config file doesn't recognize your SB5101's firmware(software). It will continue to try to update your modem with an SB5100 firmware; which is incompatible and will fail.

FWIW, while this may be causing problems, it may not be the only thing going on. I was seeing the exact same messages in the my 5101 logs and after getting 2 replacements (latest one a 5120 that does not have those messages), I am still dropping packets and losing my connection on a daily basis.
I've been having intermittent connectivity issues and packet loss for about 3 weeks now in the Mountain View CA area, typically in the late evening or early morning. I have a third service appointment tomorrow. |

Would that not be considered a "smoking gun" ? |

Maybe but doubtful.
I think the OP is losing and regaining sync OR he has some other issues which he thinks are related to the modem regaining synch and going through the TFTP process.
I'd focus on that rather than the worthless logs.

1 edit | IMO, the logs are not as you say "worthless"... that is your opinion hob, and I'm not going to beat a dead horse with you...
FWIW, I've seen and replied to this exact issue at the Comcast.net help forums many times over the last 4 months.. |

Motorola logs are notoriously worthless....everyone in the industry knows that. If the modem locks up or loses synch the OP will see the reboot process in the logs which will of course match up with the times that he unplugged it.
Thats not an opinion.....me thinking the logs being disabled is an opinion.....the other stuff is fact.

Union, NJ | Is their particular log indicating the exact action of the push, or is it indicating some typical erroneous T3's in this case ? |

Would that not be considered a "smoking gun" ? That was my original thought however after seeing those exact same messages in the logs of my first 5101 modem and still having the problems after moving up to a 5120 (and not seeing any error messages), there is definitely something else going on in my case. My outages seemed to coincide with the attempted firmware downloads as well.
In any event, I have another service appointment scheduled for tomorrow. My experience with the other 2 technicians does not leave me hopeful. I will probably be ditching comcast soon. |

I get the same thing every so often on my 5101, it was happening about every week, now it seems to be only every once in a while. However, it doesn't affect my connection at all, I wonder why it's knocking you offline? |

I am in Mountain View as well, have drop outs all day long. Up to 10 to 20 a day. Modem acts like it resets, no power loss though.
The 12th tech to my house says we have a 'network' issues in my area, yet he can't contact the network guys to get it fixed. My troubles continue today... |

|  I have this same problem with a 5101. According to what I've researched Comcast has this problem with all Motorola modems. They do two things that are wrong. One they drop the transmit voltage to under 8 DBMV. Motorola specification call for the headend to provide 8DBMV. Two they shut off the modem if their firmware update doesn't work after 7 tries. The firmware update will never work as the file is the wrong file for modem types other than a 5100. Motorola sold thousands of these surfboard modems for use on Comcast networks Nationwide. Comcast is now crediting $25 to anyone that has this problem for each time they have this problem. Most people do not know about the credit for this. You need to be specific about what the problem is. This error has now become an established error on Comcast's part. Since this is now costing them dollars they may do something about it. |
