Thank you Dray for the explanations even though I'm in France.

I'm still interested for some feedback about the xdslctl configure -snr parameter with a VDSL2 profile.

[kitzuser87430]

As far as I know in the UK the "xdslctl configure -snr" command does not work on VDSL2 cabinets; the dslam just ignores the command.

Some ASUS xDSL routers (spawn of the devil) can override the dslam SNR and power back off.

Perhaps you could experiment for us and see if the "xdslctl configure -snr" command works in France.

The table on this page http://www.kitz.co.uk/routers/dg834GT_targetsnr.htm may give you some assistance.

Hello.
I've got W9970 v2.
By default, tp-link connects to VDSL2 with a profile 17a.
How to change a connection profile?

Hi All,

And a big thank you for your contribution to this thread.

I managed to get telnet access by following this thread and i was hopping i could install lede or other custom firmware on the 9970 but it seem like no trace on the net on what is supported and some kind of howto.

Would you happen to know where i can find this ?

Thanks,
Rafik

Thank you for all the hard work in this thread 

I have just setup my W9970 V2 by following the post and files referenced below;

http://forum.kitz.co.uk/index.php/topic,17108.msg315358.html#msg315358

I then used custom command xdslctl in DSLstats and all seems sorted 

Just a note to say that it seems you need you use StatPOSTer-test3.jar now as test2 gave me a checksum error.

Hello, I'd like thank all (especially ejs) for the guidance...
I've recently acquired a TP-Link TD-W9970 V1.

I wanted a way to extract the conf.bin on GNU/Linux, so I had a look at the compression format.  It wasn't obvious so it took me a little time, largely because I don't know much about compression.  But in the end I managed to write a Python 3 utility to uncompress and compress the TP-link TD-W9970's config files; so config files can do a complete round trip from bin to xml and back.

It's a command line utility and should work on any OS/platform that can handle Python 3:
https://github.com/sta-c0000/tpconf_bin_xml

I also posted a little bit of extra information in the readme there about controlling the LEDs, timings, and where to get a couple of extra tools.
Fun stuff, hopefully someone else finds this useful, cheers.

Welcome to the Kitz forum. 

Thank you for writing the utility and making it available. I'm sure it will prove useful.

Python is a language with which I am not familiar, so your code, having taken a look, remains a mystery to me.

Hello and thanks guys. 
I tweaked my snr margin (i have a poor adsl connection).

i earned 1mb/s in dl so i don't need to return my TD-W9970v2 to Amazon lol. Tanks for all. ^^

I've updated the README and added pre-compiled OpenSSH_7.8p1 sshd server binary for the TP-Link TD-W9970 if anyone is interested:
https://github.com/sta-c0000/tpconf_bin_xml

Since we can't easily run OpenWRT on this Broadcom based xDSL modem, I used Buildroot to cross-compile several useful tools like curl, rsync, knockd, etc. for the modem.  At first I was using dropbear to connect to the device using SSH, but then I was also wanting chrooted sftp to access the drive using sshfs... so I applied a simple patch for OpenSSH to work on the TP Link TD-W9970.  It does consume more RAM than dropbear, but it's not that bad.
I though running an ssh and chrooted sftp service might be of interest to others.

I know in this day of cheap SBCs it makes more sense to run services on one of those, but since the modem is already powered, I figure why not use it...

Can anyone recommend a base os that can be used to build a factory image from the GPL? or what dependencies will be required to do so.

I tried fedora 14 as per the readme but this failed.

Hi all.

Many thanks for the information here - allowed me to (belatedly it seems) hack my TD-W9970 v2 config to allow for telnet (and using DSLstats).

The strange side affect seems to be that the Web interface on the router no longer responds. Port scanning can see that httpd is running, and ps reveals it running as well under a telnet session, however it just never responds (browsers eventually timeout trying to get the page being served up).

I'm on the latest (2020) firmware so not sure if that might be the issue?  Going to have to hard reset router back to default firmware to get back into it I think...

Any thoughts/help gratefully accepted.

[stormswift]

Hard reset and reloaded last good conf. Realised that I'd picked up a more complex Description string from posts and this was causing the web interface to hang/become unresponsive. Simple string worked and then I tried a lot of combinations and it seems like trying to put a < > in to hide the telnetd in any way (including encoding as &lt;) causes the unhappiness.

In the end settled for:
<Description val="Modem Router (running:`telnetd -p 1023 -l login`)" />

Thanks again for everyone's posts and contributions here.

Hey all,

Just wanted to update everyone on the new batch of W9970 V4, after my V2 developed a fault.

Seems like they changed the hardware, producing way more errors (had 0 with V2 for months)

The device itself feels lights and now takes a lower power adapter 9V 0.85A, no idea what chip they are using now.
