hi
i recently got a speedtouch 585v6 router so I could use the dmt tool.
Unfortunately the firmware 6.2 precludes the use of the dmt tool for snr tweaking
Ive tried downgrading the firmware without success.
I found another tool called stmt but its all in german so I cannot work out how to use it
you can find it herehttp://www.modemtool.de/download.html (http://www.modemtool.de/download.html) version 0.10
has anybody used this successfuly, if so how do you alter your snr?
thanks

Hi and welcome.
I'm not familiar with that particular program, but I doubt if it will work with the 6.2 firmware, for the same reason that DMT doesn't work with it. These programs are just friendly GUI front ends for the command-line interfaces which the various routers have, and the reason DMT doesn't support noise margin tweaking with the latest Speedtouch firmware is that the capability has been removed from the command-line interface.
As far as I know, there is no way to tweak your noise margin with the 6.2 firmware. However it should be possible to downgrade to the 6.1.4.3 firmware, and I'm sure I've seen references to people doing this successfully.

yes ive heard that it is possible to downgrade the firmware but as said I was unable to do it.
the upgrade wizard which apparently is used also to downgrade doesn't work for me
I'd be grateful if anyone can run me through downgrading the firmware or can advise on the stmt tool
thanx

STMT is similar to DMTtool, but requires slightly less configuration as it has been specifically written for ST routers... and will work with firmware 6.2x
When you install it, many of the instructions are also in English. However it does not appear to have the ability to force a resync with custom target SNR - even on a router that has the ability to do so with DMT tool.
As eric said, ST withdrew the ability to tweak the SNR from firmware 6.2 from the CLI... which means that no interface program such as dmt or stmt is going to be able to access the basic underlying commands if its not available to access within the router in the first place. :(

That's right, kitz. Paraphrasing the STMT website, it simply provides a way of looking at info from the router in a consciously DMT-like manner. It doesn't set out to do anything else; the general idea is: if your ST router will run DMT, use DMT; if not, maybe STMT will give you at least some of the helpful info that DMT did -- specifically, graphing the bitloading (so you too can discover that Radio5Live wipes out half of your top-end spectrum, and that the local radio station 6 miles up the road wipes out the other half....).
Because it uses the 'bitloadinginfo' command rather than 'getdata' it does not suffer from the 300s delay that clobbers DMT on 6.1.4.6 and 6.1.4.9 firmwares, so if you haven't got anything better to do, you can watch your modem bit-swapping in something more like real time.
The 'modemoptions' boxes are a work in progress; even when complete, they will simply show the status -- as I think we've now all proven many times over on these forums and elsewhere, there really is no way of changing the modemoptions values on 6.2.n.n and higher firmwares, however sneaky you try to be in loading configs / with or without 'root' privileges / etc.
STMT also works on 7.x.x.x firmware / TG585v7.
Hope this helps clarify.

yes, thanx for the responses
after many attempts using the wizard the downgrade of firmware succeeded.
talking about modem tools I found another one ( german of course) on a us site called orbmt, couldn't work that one out either :D
its herehttp://www.dslreports.com/forum/r18736238-OrbMT-Modem-Tool (http://www.dslreports.com/forum/r18736238-OrbMT-Modem-Tool)
has anyone used this?
....and thanx for the welcome roseway:)

@ deezel - Sorry I havent heard of the OrbMT tool before now :/
@ rwm
Thanks very much for that info rwm. :)
