Re: slow 6M DSL Montreal (evening only?) I am back again, and swap back with thomson tg784 and the speed drop back to 1M again.
So.....EdT, is this symptoms also helps in further determining the problem? thx |

Terrible speeds downtown; getting 10 meg down on a 50 meg bundle, but it's not stable, it's super bursty. Tried reconnecting a bunch of times, even saw a result of 3 megs.
Considering all the speed issues people are having recently, even in Ontario, it seems like it might be a TSI issue.

It seems like its a big problem regarding BELL and TSI is aware of it, like Guspaz said I have tried disconnecting/reconnecting several times and it hasn't seemed to have worked, so I guess I am going to just wait it out unfortunately .... 
quote from TSI STAFF
Hi,
We've identified that there are problems with DSL links as Bell is doing some changes on the network. It's going to sound odd, but right now the only way to get this fixed is to disconnect, reconnect, run a speed test and see if things have improved, if not, repeat the process. It's taking about 6 or so intentional disconnects force a move of the link your connected to. We're working to get the situation resolved in a permanent way, but right now this will get you to a less congested link as the maintenance finishes.

What is the sync speed showing in your GUI "connection" tab ?
On a Thomson it should be 192.168.1.254 to access the GUI menu.
Download DMT to determine your attenuation and distance to CO, it will also tell you what your line is capable of.
Download version DMT v7.35 for Thomson modems. Don't worry you can select English when the program installs ...LoL

I'm getting just under 3.9 Mbit/s downstream on a 6/0.8 Mbit/s sync. The downstream is normally about 5.1 Mbit/s (like everyone else on that profile). |

From what I can see, seems like BHell have you on a 6Mbs/800Kbps profile and you are getting the 6dB upstream constantly which suggest it is the IKNS bug ! |

I kept reconnecting over and over again and did eventually get back to normal:
Still no upstream upgrades :P

1 edit | Yes, sync speed is one indication, but SNR is another.
I noticed on your Thomson they have you are on interleave, OMG that is horrible ! ...LoL
Once this settles, you should ask TSI to switch you to Fast Path !
EDIT: here we go, you my friend definitely have the IKNS bug, BHell has you on a remote IKNS DSLAM and they probably misdiagnosed your line and put you on interleave !

back from running a DMT....
unfortunately it does not support firmware 8.2.7.7.0  , I can see DMT is a powerful tool, but too bad cannot use it.
thx EdT for your help, I guess I have to start a thread in direct section to hopefully get the problem solved.
One thing still confuse me, now I swap back to Bell 2wire modem again, and.....it's back to normal speed.
in 2Wire MDC I found this DSL Line (Wire Pair): Line 1 (inner pair)
Protocol: G.DMT Annex A
DSL Channel: Interleaved
DSLAM: Country: {0xB5} Vendor: {IKNS} Specific: {0x01}
ATM PVC Info: 0/35
ATM Encapsulation: LLC
It's also Interleaved....and I am still digging other info. in it. |

Hampstead, QC | now, to me it becomes a modem issue.....
try to avoid the randomness of one works and the other doesn't, I sway my two modems back and forth, but every time I got the same result.
2wire modem works at normal speed
TG784 works at 2M top...... |

If you read the TSI quote and TSI post above, it seems the low speeds are due to Bell messing with their network configuration and re-connecting the PPPoE session to (hopefully) get on a different link routing from your BAS to TSI's ERX is the only way to "fix" it. TSI's post says this requires about six attempts on average.
Maybe you got lucky and got on a good route when your PPPoE session came up on the 2wire, which made it seem like switching modems "fixed" it. |

After doing the reset trick on my modem, for the time being all seems back to normal on my 6M service.
At least Teksavvy has now acknowledged there is an issue with congested links. Thanks for sharing that bit of insider info with the rest of us, hopefully everyone else's connections get back to normal soon too. |

Yes, different types of DSL modems uses different chipsets and behave differently with the IKNS bug, but what is funny is that the 2Wire 2701 is known to perform badly with the IKNS and the Thomson is the one that is suppose to be better ! |

said by jfn0106:At least Teksavvy has now acknowledged there is an issue with congested links. TSI only stated that they were having problems due to Bell shuffling things around on their end and that reconnecting to end up on a different AHSSPI seems to solve it, not that they actually had congestion issues at their end of things.
In any case, the problems are "initiated" from Bell's side of things so TSI has very little control over what happens. |

I tend to agree with this theory that I just got lucky when I made the swap, coz the last time I tried before I went to bed last night I made a final swap to 2wire, and that time I only got 2.6M something.
but during the day time everything just works fine.
So to me the bottom line is we know the cause of the problem and we can expect an end and everything will be back to normal sometime  |

No. Quote from TSI verbatim :
said by heyyahblah:"...We're working to get the situation resolved in a permanent way, but right now this will get you to a less congested link as the maintenance finishes."
So...they acknowledge congested links and clearly suggest a workaround to help mitigate winding up on a congested link. |
