This is the fourth in a series of postings on this topic. You’ll need to read the earlier posts to see what’s on here.

The big new today is not that Telecom has fixed the problem. They have not, to my knowledge. It is that a fellow up in Auckland has devised a functional work-around until Telecom does get things sorted out.

You can find a “How To” document on on the fix here:

Read everything before trying this and if it doesn’t work for you, do not contact me – I am not going to do technical support of this.

You are welcome to add comments to this post, however, to record your experiences with this fix so others can learn from your work.

    http://forums.whirlpool.net.au/forum-replies-archive.cfm/620659.html details how to change the ADSL modulation on a netgear DG834G router (which i have). I’m unsure about which modulation i should be using, but have selected ADSL_G.dmt, have just made the switch, rebooted router and will post up to geekzone the results, which one below is equivalent to the setting proposed by neil?

    actually, ADSL_G.lite is what we want, it has reduced my downstream from 7000 kbps to 3552 kbps, but let’s hope it’s more stable;)

    DownStream Connection Speed 3552 kbps
    UpStream Connection Speed 160 kbps

    The mode Neil found (ADSL (ITU G.992.2) cuts downstream to 2656 kbps and upstream to 160 kbps (at least that what my ADSL 502T is reporting now). I’m happy with slower speed in exchange for a solid signal. Yeah!
