Topic # 27222 18-Oct-2008 12:31

I have a Telecom Adventure Broadband plan which is ADSL2+ with uncapped upstream/downstream speeds. I am wondering if there is anyway I can improve the upstream bandwidth by changing any settings in the modem (even at the expense of sacrificing some of the download I am getting).
I am getting a maxium of 166kbps upstream but about 18Mbps down. I have tried forcing the connection to ADSL, ADSL2 and ADSL2+ using the command line interface on the Thompson TG585v7 wireless router and I cant get any higher than 166kbsp upstream in any configuration.
I understand that ADSL2+ has a maximum upstream speed of approx 1.4Mbps. The details of my line are below.
Thanks in advance for any help.

DSL Type:	G.992.5 annex A

Bandwidth (Up/Down) [kbps/kbps]:	163 / 18.518

Data Transferred (Sent/Received) [kB/kB]:	0,00 / 0,00

Output Power (Up/Down) [dBm]:	12,0 / 19,0

Line Attenuation (Up/Down) [dB]:	5,0 / 11,5

SN Margin (Up/Down) [dB]:	42,5 / 12,0

Vendor ID (Local/Remote):	TMMB / BDCM

Loss of Framing (Local/Remote):	8 / 0

Loss of Signal (Local/Remote):	1 / 0

Loss of Power (Local/Remote):	0 / 0

Loss of Link (Remote):	0

Error Seconds (Local/Remote):	3 / 0

FEC Errors (Up/Down):	0 / 227

CRC Errors (Up/Down):	0 / 0

HEC Errors (Up/Down):	92 / 0

You may need to wait for the uncapped upload to be introduced as Telecom are rolling it out over the next few weeks. You upload still looks capped, which probably is the reason why.

Find me on Twitter!

It is my understanding that Telecom are still in the process of migrating customers who have a 128k cap upstream to FS/FS on current $49+ plans. So sorry you just have to wait :)

ok, here's hoping that that is the case.
I only subscribed to this the day they launched the new plans and didnt get any communication from Telecom to say that the upstream speed would be capped for a while. I can understand that if they have existing customers that they are upgrading that the rollout of this may happen over time but if you are a new customer signing up to a new plan advertised with no cap on upstream then that should be what they give you.

I would give the help desk a call, I don't think this should be the case for new connections? Or did you transfer from a Wholesale ADSL service with a 128k uplink? Perhaps why this plan has remained capped.

I have emailed asking for confirmation if my upload speed is capped. I was previously using a Compass wireless service because I couldnt get a working ADSL service despite living in a central Auckland suburb - they have now cabinetised the area and I am close to a cabinet and get a working service at long last.

Try lowering your SN margin with dmt tools

That is what i was thinking I might be able to do but I cant find a DMT tool that works with this route/modem. The DMT app said it didnt support the firmware version.

DMT doesn't affect upstream sync rates anyway.

I will confirm that altering your upsteam connect rate will not improve your upstream speeds. Your current upload speeds have been shaped to the previous Upcapped/128kbps profile and will eventually change in the coming weeks (as the others had mentioned). There is no specific time when the profiles will be changed, as of the 6th October all data caps were increased except changing speed profiles will take slightly longer. With your current connect rates, you should expect possibly 800kbps (slightly more or slightly less) once the change takes effect. And this will be 800kbps as a connect rate however throughput will will vary.

Those of you who said I had an upstream speed cap in place get 10 out of 10. It turns out that this was the case. My service was provisioned the day before the official launch of the new uncapped plans so it was provisioned with the upstream cap. I'm not sure when the notification to existing customers went out about the changes but it would appear that those that joined up between the date that notification went out and the official launch of the new service didnt receive anything telling them about the changes.

The happy ending is that now that the cap has been removed my modem is reporting a much healthier upstream speed of nearly 1Mbps and downstream around 18.5Mbps.

Nice connection :)

Mine will never reach that, but all looks good for you now :)

I just checked my ADSL2+ upstream rate this morning, and was pleasantly surprised with 780kbps. Its nice that we're finally getting some 1st world speeds.
