Re: SpeedTouch 516 Tweaking :)
Good to hear.
The first hop when you set the modem to routed mode will be high because the modem set to respond to ping at a VERY low priority. So dont look at first hop.
Ping google.com as bridge then ping it as routed you'll see no difference. I tried it.
Bridge
MSS/MTU 1452/1492
Routed
MSS/MTU 1440/1480
you can always use Raspppoe which is what I do to get the 1492 MTU 
Difference in speed is 545kb/sec vs 550kb/sec. |

For 'DMT' to work it might be necessary to use the
"disable Pingcheck" option (see "Misc. Settings"),
that's all there was to do to make it work too!...

Hello,
Sorry to disturb this brilliant topic.
I have a question:
I use a SpeedTouch 546 v6 and just upgraded the Firmware from version 6.0.5.0 to UK 6.1.4.6 after reading mostly all 35 pages.... ouch !
DMT version 7.21 does not work properly anymore: The three windows are grey and If I enable SNR-Monitor (start), the modem reboot. 
Is there a clue ?.
Thanks for any advice.
Edit ** Just got DMT 7344 and it works fine... Sorry

| Hi,
This reboot thing is a gift from control-freaks of
the SpeedTouch team in Brussels... It's their way
to demonstrate how highly they think of 'DMT', but
you can thank the european ISPs because it's those
morons who made such weird deseases even possible:
Without their insistance, Thomson might have shown
more friendliness for the few technically oriented
customers who may choose to purchase a SpeedTouch.

| Hi,
I agree...
I use Alcatel SpeedTouch since 2001 with the first USB venerable "Green fish".. Then got a ST-510 and be happy for years. I switch to a ST 536 v5 for a while and bought (on Ebay) my ST-546 v6 just 3 days ago.
My line is 4,2 Km and 53 Db attenuation. Of course I can't reach the 8000 Kbps down and 1024 Kbps. DMT helped me to get the maximum (around 3800 /860) depending of the inter-modulation from others lines. Too many Adsl customers around me (more than 45.000 for one DSLAM)
Thanks for nice job. |

| Within my ST-536 I have tried to play with default tones (12) to 10 or different values. This just affect the Upload margin SNR by moving down the speed from 992 to 776 kbps...
I did not find how to get more download speed with a such long line with 1 km aerial wire copper with at least 20 Connection boxes on the way....!!! (Clean at home). |

| Hi Old Computer,
I was hoping there could be a way to use some very
old v4.2.x FirmWares on a v6 SpeedTouch but that's
not likely to happen, i also believed that there's
a symetric CLI command for "maxbitspertoneUS" like
"maxbitspertoneDS" but it must have been in awaken
dreams only... Then, what about "extendedBWmode"?
Isn't there any real tweaking which can be done???

| I have to check your suggestion about "maxbitspertoneDS". The CLI is not very easy to read for me - My English is too bad - and there is no French translation for latest version.
About "extendedBWmode"... I have to learn about...
My need (and for others) is to force remote DSLAM to send 1,5 Db more for download in order to increase SNR then Speed sync. I stick with 18 Decibels and DMT when using registers 0E or / and 0D does nothing. |

Sra is supported by all French DSLAM. So it is not a problem with the ST546. (sra is NOT disabled).
In fact, I would force the dslam to send more power to gain a little speed (SNR). With 19.5 db (down) the speedtouch synchronize at 4,228 kbps at home. Actually I got 3616 Kbps and 18 Db. (Seen during long holidays when most people are swimming somewhere...) |

I wish i could experiment with ADSL2+ but Spectrum

I'm a Telus user, so you can add me to the list of "Telus Experiments". :P
