Hi all.
Yesterday I upgraded to telecoms 150gb plan from my 120gb plan and now my download speeds have halved. I was getting 1.5MB download speeds before the change.
I'm not that knowledgeable with modems but had requested interleaving being switched off years ago as I game a fair bit. Would the new plan have changed my settings with telecom?
Also my downstream data rate in modem (dsl-504t) reports 7547kbps which seem to be Adsl 1 speeds.
Does anyone know what could be going on?

I'd ring Telecom first and log the problem as it may well be a configuration issue.

I've had similar issues which have been caused by the ISP but I've also had plan changes coincide with other faults. So while your fault report is working through Telecom you can independently look at your setup. Search these forums to see what other people have done to resolve their adsl issues.

You might want to check out a new modem for a start, those old d-link's are horrible and most models of the 504 don't work well at all with Ikanos linecards which are in the vast majority of ISAM's now.

Some versions of D-Link DSL-502T firmware have a bug under ADSL2+ interleaved operation that causes the exact issue you have described.

Just call to get interleaving turned off as you had on your old plan and the speed limitation caused by the firmware will no longer show. Most Telecom plans come with interleaving on by default.

Of course you can always upgrade the firmware as this issue has been fixed in a subsequent version of firmware.

Well Ive just been with telecom support for the last 30 mins and have tried everything they suggested which was all the basics I've tried already. I struggled to get a straight answer whether interleaving was switched off but got a tentative answer in the end so am not entirely convinced its off. Was told to do a factory reset and maybe the modem will download any new firmware available...??? Not sure how it does that automagically!
Have searched D-link for firmware but doesn't seem to be supported any longer.
Does anyone have any experience with this particular modem and how I can get full speeds again?
Thanks

Chorus has spent $1.4 billion on making their ADSL broadband network faster. Why not spend a couple of hundred to make sure you are getting the most out of your connection?

Yes tried restarting.
Thanks for the links but I had already found them and my modem says 504T/TX  V.B3
I don't see firmware for my version!!!
Thanks for your help so far tho.


UPDATE: Rang telecom again to get a different support person and they confirmed interleaving was ON so thought problem solved.
After testing ping speed has halved to 41 so that's better although still not as good as before the plan change as I was getting 15 pings. Download speed still slow at 6Mbps.
Problem still not fixed.

It doesn't sound like interleaving is off to me but be aware it can take a few hours to a day once the request is acknowledged.
Best way to get interleaving turned off is to email them through their website:

If you choose to upgrade the firmware on your modem, this is the download link for the Telecom supplied DSL-504T modem:

Sorry, I meant to say that after checking again with telecom they said it was on and they would turn it off.
I tested speed after they confirmed they had finally turned it off.
Still, I might email them just to make sure.
Cheers

Hi firstly give the link the bums rush they are well past use by. Next once you've got a new modem if its not sorted then get on to a tier 3 support person and ask for a profile change that's less conservative. I have had the exact same issue before, originally on a high rate with interleave on, changed to interleave off and the system (chorus end) knocked it to a very conservative profile that pulled the rate to half before. Intervention of higher tier rep was needed to both understand and do the business.

Hi, I suspect its more to do with the profile your on, but as others have said various generations of those modems have issues with non interleave. So in light of the fact that your modems a dinosaur, get a nice new modem, a TP-Link as linked below is not a bad beast, then if tackle the profile issue.

I appreciate your help. I know my modems really old but it just bugs me that yesterday all was fine and now just because I changed plans I have to fork out for a new modem...it goes against my grain that this can't be fixed without buying a new modem.
Yes that link you posted seems to be all I need. Telecom will send me this one for $50 if I want. What do you think?

Why don't you just sign a 12 month contract with Telecom, get 2 months free and get a free modem?

Yes the problem may have only occured because of a profile change - but at the end of the day the issue occurs because the modem is an old, poor quality device that has compatibility issues. If you upgrade the firmware it seems it will work, but there are still stability issues with these old modems and newer Ikanos DSL chipsets. The new modems are vasly superior - if you don't want to spend $50 on a new modem you will something for ~$10 on Trademe that's also far better than your old d-link.
