Re: Upgrading Firmware on Thompson DCM475 Mlord, I'm in Ottawa, in Orleans. How long does the flash take if I'm able to drop it off to you?
Thanks for all your work on this one! |

| It takes about 20 minutes but you may want to plan to be there for a half hour, just in case. |

Lothario & Shoeman1975,
Allow about 30 minutes, start to finish, for updating the modem.
If you (or others) want this done, then PM me (click on mlord at left, and send me a Private Message aka. "PM").
Cheers |

Been running the updated firmware for a week now with no problems. It also appears to have resolved my periodic disconnect/reconnect problem which was my impetus for getting the upgrade done in the first place.
Thanks again for the help mlord.  |

| Do you have channel bonding yet? My modem has been relatively ok but am still getting it upgraded. |

said by HiVolt:Rogers has the capability and should have no problems to send firmware updates to modems that are accepted to use on its network.
They did it before, I don't get why they wont do it again.
Basically it's not really mentioned but, if a company stop or refuses to give customers a service for something, it really shows how much Rogers dislikes Teksavvy (unofficially of course). Heck for some reason I get vibes that they brainwash all their employees to hate competition.
Because the way I theorize this is:
If Rogers didn't have competition, more people would have to 'resort', that's the keyword, resort, to their plans and cough up a larger amount of dough. Now with Teksavvy and third party internet, they feel that they are 'losing potential profits' now that they can sell usage to Teksavvy, etc. but not keeping the customers so they can't milk them. They think that causing distress (but they obviously won't admit to that) is a way to make people leave third party back into their milking game.
The thing about Canada, is that almost every large position of power, be it corporate or government, is into 'milking' or abusing something to it's non-existent. Today, you are starting to see the cracks of the social system, with unions and such at war with government on 'wanting to be spoiled with more money', and government wanting to pay off the debt but can't seem to 'stop spending money'...
Just recently I read that the construction industry was corrupted by a Canadian line of Mafias and was only figured out and publicly testified this week.
Slowly, but surely, all things 'power' is heading to the direction of corruption.
----
As for this thread, I have a DCM 475 also but I don't see any changes on it, other than weird packet loss and lag spikes that occurs randomly every other day...
I totally check all my network and none of them are causing the huge 600ms latency spike across outside from my home. Could be the 'peak' hour thing, but I find that strange because it's not like Teksavvy's own nodes are hitting max capacity that easily right? |

Close quarters |
The latest one actually overhung the flash, preventing easy access to the pins. I managed to slide my grabbers under the heatsink onto two of the pins, but the third pin on that side was not accessible. Fortunately, this was the +3V power pin, so I used the closest pin of the nearby white header instead. Worked fine. |

kudos:5 | Very annoying.. I guess it is Dremel time 
I might have to break out the individual test clips actually. It is only a few connections, and those big all-pin test clips aren't that easy to attach, so I might be better off with your setup anyway..

1 edit | I really like these EZ-Hook XKM grabbers. They latch onto SMD pins quite solidly and without shorting on neighbouring pins or clips.
Expensive, though. And very difficult to solder wires onto. Not an issue for the Logic Analyzer, which has the proper mating connectors, but for this rig.. somewhat fragile.
I've got a shipment of very similar looking clips on the way from China, with proper solder tabs. I plan to switch this rig over to those once they arrive, assuming they can latch onto things as well as the XKM grabbers do.
EDIT: there is a variant on the genuine XKM hooks that might work better: XK25SS hooks are designed for easier attachment of patch cables, and look like they could be soldered onto as well.

| Thanks Mlord,
Everything working fine so far. I think Teksavvy owes you a free month of service for what you are doing for some of their customers. |

A gesture from TSI would be nice, but they definitely cannot afford my usual hourly rates. My wish is that the pain endured figuring out this fix can help keep others going on TSI Cable. That's why I do the upgrades almost for free.
As much as I'm among the first to criticize their lack of great customer support these days, there's really no good alternative to TSI.

Its really good that these forum members have figured this out.
Its really bad that a firmware update can't be sent thru the system to upgrade existing products

It CAN be done, Rogers just refuses to do it. |

When I picked up my own DPC3000 the moment it sync'd with the network Cogeco pushed the latest approved firmware to it. Of course they can. I do wonder how often they brick modems when they do it though.
For example, with the DCM425s I get, I have to upgrade the firmware on all of them. Unlike with the newer Docsis 3 modems, I'm instructing the CPU to take up a firmware over TFTP. About 10% of recent batches of DCM425s have become corrupted, and another 10% have failed to flash just before becoming corrupted, but still can't be upgraded.
My current working theory is that the flash chip develops a bit error over the years, and from there when you try to upgrade it fails. I'm not totally happy with that theory, but..
Anyway, we know there are redundant firmware images to help avoid bricking, and the process they are using is probably more reliable in the first place, but there must still be some bricking on upgrades.
My biggest concern is how they claim some firmware versions that are originally approved are suddenly not approved for no technical reason. There are a HUGE number of ST52.05.49 DCM425s out there that work perfectly. Once a line issue effects one of those customers, Teksavvy tells them they need to buy a new modem.

kudos:3 | I believe Cogeco pushed out at least one firmware update to the DCM425, so I don't think it is all a horror story as far as upgrading those modems go. |

kudos:5 | Well, that's a puzzle to me too, to be honest I know that Cogeco is distributing some DCM425s with ST52.05.49, yet the approved firmware for Start is ST52.05.45.
Anyway, I definitely don't think it is a horror story. I definitely agree that Rogers should be pushing firmware upgrades.
However, the idea that ST52.05.49 is suddenly not approved when it works, and it was previously approved (I assume, Teksavvy was selling modems with it), is ridiculous.

With Cogeco the firmware revisions is really a non-issue. So long as the modem is an approved model and revision on their network, Cogeco will just push out the firmware they want the modem it syncs to the network. If they do a network-wide firmware upgrade of a particular model of modem, both their retail and TPIA customers will get it.
Rogers is just being retarded about everything. And to think, Cogeco was portrayed as the bane of ISPs who wanted to do TPIA with them, and now it seems like they actually know what they're doing and handle things properly - though I would certainly hope so, since their capacity pricing model is almost twice as much as Rogers (for now, anyway) |

I wonder what the cause of the 02.08 problem actually is? Now that we've cracked "fixing" the DCM475 modems, I'm wondering what the actual problem is with the 02.08 firmware. Sure, some people with it suffer frequent disconnects/reconnects, but.. why? And why not everyone with that firmware?
One idea, is that it's related to the hourly DHCP renewals that Rogers is switching to in several areas. I wonder if perhaps the 02.08 firmware doesn't deal well with DHCP renewals.. not much of an issue for month-long renewals like we used to get, but with hourly renewals perhaps..
Anyone got any evidence one way or the other?
Thanks |

I wonder if perhaps the 02.08 firmware doesn't deal well with DHCP renewals.. not much of an issue for month-long renewals like we used to get, but with hourly renewals perhaps.. The general theory until now is that the hourly DHCP renewals are put in for areas undergoing upgrade to 4 channel upstream bonding, and that Rogers switches the area back to 7 day renewals after the upgrade is complete. You'll see some mention of that in the 4-channel bonding threads.
The problem with the 2.08 firmware? Who knows.. Last year, or more like the summer of 2011, it was believed that the 2.08 firmware was actually causing some disconnect problems. Like, the 2.08 firmware didn't work well with some CMTSs, in particular associated with Brampton. I think this is the main thread:
