Re: switched to EXTREME now torrents are SLOW!>?!?
They don't offer Toshiba's anymore, so that's no longer an option. Just gotta keep putting the pressure on Rogers and demanding refunds each month because we're not getting the service we all payed for. |

It works @ first, but slowly degrades and eventually kills my internet (for most applications).
Using SB5100
Is the only solution to try a trade for the toshiba cable modem? |

I agree with hereto, its not a bittorrent problem per-se. Its actually 'multiple upstream TCP connections cause massive service degrataion'.
I see some people have had success it getting Rogers to fix whatever it was. Ill try plugging my SB5100 back in and see if its fixed for me.
BTW: You guys cant upgrade your firmware, nor will you find any firmware released publicly available on the web. It must be done from Rogers end or from a serial connection. (which is probably not built into the production boards and even if it were probably requires a slightly custom dongle)
I dont think its really a firmware problem so much as a RF misconfiguration problem. |

For anyone having slow torrent issues - are you sure you aren't having the same issue as the "upload cripples downloads"? I have the problem where, when achieving my max upload, I can't even load web pa.......
That's not it.... Download sucked even if i'm uploading at 10kb/s..or less
So there's definately something fishy going on with rogers..

I had this "bi-direction transfer" issue when I was with Bell Sympatico DSL in Kingston, but never with cable modem. In the beginning everything was fine too, then the disconnects got more frequent. Here is my thread if anyone is interested ...

For anyone having slow torrent issues - are you sure you aren't having the same issue as the "upload cripples downloads"? I have the problem where, when achieving my max upload, I can't even load web pages. There is a very big issue in some areas with bidirectional transfers - uploading kills downloading - big time. I notice this in my torrents too. BUT - when I first got extreme I could upload a torrent at 80 KB/s and still download at 300KB/s +. Try using an ftp program (I get the best speeds with cute ftp) to upload somewhere, then while uploading, try and download - you may realize this is not a "torrent" issue, but a "bi-directional transfer" issue - just a suggestion....  |

Looks like ChrisFF has found the problem, but I have no way to fix it  I'll check the web for firmware updates to the Moto SB5100, but I do not expect any luck there. And to think, people told me I was lucky to get this modem when I signed up for Extreme 
(BTW, this took me 2 tries to post, because my BT client is using up a whooping 15k down/20k up, and the browser timed out while posting ) |

Well ChrisFF seems to have located the problem. Unfortunatley, it seems there is no quick fix available. I'll keep checking Motorola's web page for firmware updates, but I do not expect any help there. Since I "bought" this modem from Rogers, is there any chance of exchanging it for a Toshiba or something? When I got the modem, I was pleased, as most posters were hoping for the Motorola SB5100; looks like they were wrong . |

Couple things I just found out that may help you guys.
First...Turn off UPNP on your application.
Second...Change your Torrent Ports. It looks like Rogers is doing something to Limit Torrents. I changed my Torrent ports to 56881-56889 and Whammo...My Speeds where Way Faster. |

These errors in your modem log, Frankii, mean that you lost connection and the modem failed to contact the CMTS and the DHCP server |

Thanks ChrisFF, with all the things I tried, thats the only one I couldn't. (due to me not having another modem)
ChrisFF, do you think there is just a few people that are having this problem? Wouldn't we hear more about it if it was a general problem? Could it just be the firmware on our modem that is doing this?
Well, anyways, im going to go surf the net if anyone is getting the same problem. Maybe someone came out with a way to update the firmware on this POS 
and btw, i have this log from my modem, are they normal?

I fixed it. Youre not going to like the fix though.
The problem was the SB5100 itself. Im not going to go into detail but I guess there IS a problem in thier bridge for certain circumstances and modulation profiles. Im going to write thier tech support guys a note detailing it and if they get back to me ill help them debug it.
I replaced the SB5100 with a modem containing a custom firmware with the MAC hardcoded equal to my SB100. After switching to the new modem everything worked perfectly. I guess having 75% of the global market share doesent neccesarily mean you have the best product. Multiple upstream TCP connections no longer caused severe degradation. I had some torrents going at a sum of 500K/s down and 80K/s upstream simultaneously (needed to leave a bit of upstream headroom for ACKs) while still maintaining 50-120ms ping latency to a site that would see 40-60ms under unloaded conditions.
Obviously, my solution wont work for you so I suggest you try the following:
a) get a different modem, the Webstar or Toshiba (if you shedule a tech to come visit you they should be able to do this)
b) get Rogers to change the firmware on your modem (good luck with this)
c) get DSL |

Anyone found a fix yet?
Its getting to be a pain, each time i leave my torrent on, my roommates complaine that they cant chat on MSN and surf and stuff. And my trafic is only like 10k down and 20k up |

I called up Motorola broadband tech support and asked them if they knew of any incompatibilies between the SB5100 ethernet chipset and others or if there were any known issues with the internal bridge and bi-directional traffic. No known issues.
So if its not an ethernet problem, (seems unlikely as I have tried about 5 different ethernet cards/chips) not an internal bridge problem (also unlikely as there are people for whom it works properly and im guessing most people have the same firmware as me) yet the RF is OK it MUST be routing /router config or CMTS configuration.
Does know a way to get straight to level 2 or 3 tech support at Rogers? |

Allright. My troubles continue.
I exchanged the modem yesterday for a different SB5100 in the hopes it was just a dud piece of hardware. No dice. Exact same problem with bi-directional traffic causing massive loss and stalls.
So then I figured I would try a new router so I picked up a WRT54G since a) people seem to have alot of success for it b) the source code is GPL and there are lots of nice modified firmwares for it c) I want to hopefully setup a wireless network with my buddies on the same side of the building on 11th and 4th floors (im on 7) d) it was on sale for $90
Anyhow get it home, set it up, still have huge problems with bi-directional traffic. LAter I tried plugging the modem straight into the linux box so its not just a windows thing. Boo.
Today im going to contact Motorola broadband support and see if they are aware of any issues and after that I am basically fresh out of ideas. In the meantime however can people with the extreme service, SB5100 and working bittorent post up thier firmware revisions for me?
Mine is:
Software Version: SB5100-2.3.1.3-SCM00-NOSH
Hardware Version: 3
MIB Version: II
GUI Version: 1.0
VxWorks Version: 5.4
Thanks |

Ok I spent a couple hours fooling with it last night.
I have determined it is NOT a rogers problem. While I experience massive loss and TCP stalls on the CPE side with bittorent running you can still ping the modem from an extrenal site with no loss and low latency. In short it looks like both the RF and routing are good.
Thus the problem lies between my PC and the modem.
Which leaves:
TCP Stack
hardware level ethernet incompatibility
dud modem/bad hardware
Im leaning towards the ethernet problem as I messed with my TCP settings by altering the RWIN up and down but that had little effect.
Im going to look up the SB5100 tech support page or perhaps call Motorola and see if they are aware of any issues related to ethernet incompatibilities. |

Switched to extreme myself after I was stuck back on a teryon from a 3mbps doxis performance. My conn died and they switched modem on me and screwed 300kbps downloads down to 150.
My current torrent as i write this is @140 down 80 up - 14 peers/22 seeds - way good if you ask me.
My downloads are at 560kbps to 600kbps - just downloaded VSSP6 from MS in seconds.
Overall - I am extremely happy with my extreme - for now - 4 days consistent performance.
I know this is not read often in comparison to complaints and a complaint is why I switched but I thought give credit where credit is due. In the meantime I'll be watching it once bitten... |
