Do they generally just set up new connections on area defaults (i.e. everyone in K1X XXX is probably 3 megabits)?
Thanks in advance! |

If tweaking is required then v6.1.0.5 is the
last FirmWare available. Otherwise, try them
all for about ten days each using this tool:
»Yet Another Modem Statistics tool
...then come back here in four months or so
to share the result of your own comparisons!
Oh, and don't forget to save your log files!...

So...after 52 pages of reading...
What firmware number is recommended for those of us with poor connections? Downstream is 60db and SNR is 6.5, but I get 3000/800 sync perfectly, but hoping to improve stability (I disconnect a few times a day it seems)
I currently use the newest firmware, but I have a feeling there's better... |

Arcanac might have been looking at someone else's line. Your stats are great and you're probably on a remote. 5056/800 fast path shouldn't be a problem. |

hello,
recently i asked my isp [Acanac] to switch me from interleave to fast path, as i was having far higher pings than i wanted (over 50ms for just about everything). on interleave, i used to have 5056/800 down up and now i am stuck on 3008/800 after having been put on fast path.
i asked the guys at acanac for my line stats after this happened and they told me that my line was doing this:
SNR 14 down, 14 up
Attenuation: 53 down and 35 up
and told me that i could not get any more out of my line. my modem, a versatek versa 170pr, was reporting:
SNR: 30.5 down, 11 up
Attenuation: 10 down 4 up.
given this, i wanted to double check with another modem, came across this speedtouch and got DMT. here is what the modem gives me:
with this in mind, is my ISP lying to me/giving me false information? are the stats from my modem trustworthy? am i maxing out my line? do the stats even look normal? from what i can tell, my stats are basically too good to be true...
I've verified the stats on my friend's line and his line gives a far more normal curve, where the blue area is not practically flat, and his modem says he is pretty much using RCO ~70% for up and down.
in any case, if anybody can shed any light on my situation, it would be greatly apreciated. Going from 5 mbit to 3mbit is a loss of 66% speed. worst of all, pings have not dropped more than 5 ms.
thanks to all who input their opinion |

Hi Chopp,
There's no reason to upgrade if you observed
no difficulties. Your router problem appears to
be quite common around here, the last related
post i've seen was this one as i recall, actually:
»Access Modem on WAN
I don't use a separate stand-alone router myself
so you'll get better advice from router owners...
'DMT' can be run under 'WinE' sometimes, the one
application which runs even more successfully if
using 'WinE' (e.g. Linux/OSX) is 'RouterStats' or its
trimmed-down version 'RouterStats-Lite'. There's
no spectral response graphic in 'RS' but i yet got
to see it fails in a 'WinE'/Linux environment.
Addendum:
Euh... And 'RS'/'RS-L' is said to generate diagnostic
logs too which may allow one to create noise curves
but still no spectral response graphics, though... |

I haven't experienced resets & disconnections as far as I can tell anyway.
What firmware would you recommend I upgrade too? I did have the modemoptions enabled, but was not sure what to change anyway.
Also what changes can I make in my x-wrt router, to be able to connect the one and only M$ box to the modem with DMT, without having to connect it directly to the modem?
Thanks

Ah, and before you do, check if setting
MoDemOption register 0 to #00)h helps:
i notice you didn't activate the extra
'DMT' panels, maybe it's time to do so. |

Hi,
Are you experiencing resets & disconnections?
You can try to upgrade the FirmWare so that
the MoDem will only negociate for an ADSL v1
connection. The DownStream rate would still
be comparable (6016 Kbps) while the UpStream
rate should become 800 Kbps, which i suppose
will take care of the bottleneck you've got...
Does 6016/800 Kbps sound acceptable to you?
The DownStream SNR Margin will most probably
take a hit but yet remain within suitable limits.
The UpStream SNR Margin will certainly raise
by a couple dB at 800 Kbps; this would bring
more stability but i'm not even sure you really
need it!

Hi again,
Sorry but there's no such conclusion in my reply.
The Attenuation level might remain immuable as a
rock even if you experiment with RF "chokes" but
who can say it's the case until it has been tested?
I do my best so that clues about the "Noise" issue
are provided by this thread and the one which it's
linking to, i published numerous illustrations there:
»From the ground up!
You'll learn that SNR Margin curves often failed to
describe reality, i can even refer you to old threads
where the spectral response envelope looks better if
the MoDem is located away from one's demarcation
box, using a long/cheap non-twisted phone cable!
I've discussed how the use of toroidal ferrite cores
as RF chokes may lead to some paradoxal results;
i can also show you a curve where one section just
looks great while its counterpart is some nightmare
come true and yet, in fact, the situation happens
to be different. Now, if some curves lie what must
we expect of mere static numbers which many of us
have seen changing by the minute!? My suggestion
is that you collect long term (24 h) "noise" curves,
it may very well open your eyes on the big picture.
It's not perfect, there's time & effort involved but
that's all i got to offer. Maybe others know better
but i'd probably call this gambling on your account!
My advice isn't to give up but to acquire a proper
perception of the context. The choice is yours, is
it worth my spare-time and yours? The content of
your next post will tell me if we can go any further.

So basically their is nothing I can do because my Attenuation of 62 is to high???
Also, with my noise set to the min I have an RCO of 48%. But my attenuation is still 62...does that mean my line is noisy as hell and their is nothing I can do? |

Automated (timed) tweaking should be good enough then, i
wonder if BoxFan (author of 'STMT') would mind commenting...

the 516 doesn't fully support the adsl2+ spec which is what you want =(
the ability to change profiles as the line gets better or worse doesn't really work yet... give it a few more years before jumping onto one of these units. I have a 3com whic his capable of this an its very rough getting the right firmware which is stable on it. |

Hi,
We get little control using Thomson's MoDemOption
and the matter of FirmWare versions remains to be
explored but i can attempt to testify based on my
own experience and then i'll extrapolate from there.
This capture shows the best RCO numbers i've ever
seen for my present line, i believe. It's confirming
my assumption that under normal conditions i must
be able to get on 6016/800 Kbps FastPath!!! Noise
obscures such a prospect, most unfortunately, but
it's not impossible that some day i'll get this solved.
Right now, it's obvious there are afternoons during
which i might have the best profile available for the
money i spend but, until only a few days ago, i just
hadn't realized i was able to restore my connectivity
on evenings using an ST + 'DMT' tweaks. Relatively
to our present case (yours), a DownStream RCO of
50 % or so may sugest that you have room for more
speed indeed but it depends on how quiet the line is.
Being this far away doesn't help it at all but i can't
tell more without the suitable noise curves anyway.
Back to my illustration, what i know is that i'd have
6016/800 Kbps FastPath during dry afternoons only
and i'm not sure Bell would leave it as is, indefinitely,
while the "latern" resources would keep warning the
phone company that my speeds vary in this fashion.
Maybe there's a similar option for you, maybe not...
I wish ADSL were made sturdy enough to fall-back
and "repair" itself automagically but that's not going
to happen on the Thomson SpeedTouch 5x6 series
if i can judge from what i've seen and read since i
bought my ST546v6, about a year and a half ago...
I believe the Siemens SpeedStream 4200 is able to
fall-back to 4032 Kbps during a noisy episode but
i could notice the connection wasn't as satisfying
as i'd like it to be. If this is how ADSL works for a
growing number of customers lets welcome ADSL2+!
In the meantime, you should consider installing new
FirmWare which 'STMT' supports so that long term
"noise" curves become an option... Once you got a
better perspective on how the line behaves you'll
gain confidence about what the next move must be.
Let me reming you that RCOs in the fifties would
be good news only if you have moderate noise, as
when living in sub-urban country-sides, perhaps.
Who knows, you may be lucky. |

@teksavvy.com | reply to dcman
Also! If I bring the noise bar down to 2 notches above the word minimum, my RCO is %58...I assume lower is better?? Thanks. |

| reply to Bicephale
I did the setting you suggested for my modemoptions my RCO DS% went up from %66 to %68. My SRM went from 11 to 13.5, and my txpwr went from 16 to 15.5, AFTER I slid the bar up to were you have it. Is this bad or good?
Hopefully my modem stays in sync for atleast 12hrs or so lol, in which i'll take another screen cap. But do you think I would be able to attain a 1.7mbit connection on my line? Like how am I suppose to b*itch to my ISP and have them b*tch to bell that I want it switched for testing purposes when they immediately refuse anyways? FRUSTRATING!!! |
