I just upgraded my broadband plan so I have FS/128. Also my area (Homai Manurewa) supposedly has ADSL2 installed according to Telecom. However I am only getting about 2.1mbps. Slingshot tested the line and was getting about 4mbps. Was wondering if anyone can help me out or should I be happy with this (at my parents house it gets about 4mbps and adsl2 isn't even installed there)? I am using a dlink dsl-g604t, these are the statistics:

ADSL Firmware Version: 5.00.04.00 - 5.00.03.00 - 5.00.03.00 Annex A - 01.07.2b - 0.52
ADSL Software Version: V3.00B02.NZ.20060711
Line State Connected
Modulation ADSL_2plus
Annex Mode Annex A
Max Tx Power -38 dBm/Hz

Item Downstream Upstream Unit
SNR Margin 12 21 dB
Line Attenuation 36 22 dB
Data Rate 2998 164 kbps

Full speed for what the line will allow

johnr: Full speed for what the line will allow

So do you think my line is crappy or something? What sorts of things can I try? I've tried an isolation test and it doesn't seem to make any significant change to speed.

I rung up slingshot earlier and they were going to increase the latency and reckoned that should give a more stable and faster connection to about 3mbps.

You need to know the distance to your local exchange and quality of the line

You might get better speeds by setting you modem to adsl1 as it provides better speeds over longer distances.

I find I get better speeds on adsl2+ then asdl 1 here... That was the case on the crashprone dynalink and on the current netgear. The issue I have is that unless I force it, the modems will pick adsl2-re which is really really bad for speed and latency with a upstream of often 64-96k - so try all modes the modem offers and see which is best.

Hi hellonearthisman and richms,

I have tried quite a few different modulation types on my modem. Changing to ADSL1 does make a small difference to the data stream down rate but not really noticable. I'm expecting another 1-2mbps on my connection but maybe the wiring is no good in the house. I suppose I'll wait for slingshot to make some changes to the settings of my connection and see if that makes a difference (they were going to increase the latency which they say will increase the speed although I have no real idea how that works?).

Looks like they have increased my latency (its 80ms now) but no change to speed. Damn

The SNR and Line Attenuation don't look that bad in my opinion. I would suspect house wiring or interference of some sort.

You can use the map bewlow to check what exchange area you are in and when/if a cabinet will installed to shorten the distance to your place.

Note: The site won't show you the exact location of the exchange just the area covered.

hi thanks for the reply ragnor. It says that our exchange area has already been installed with adsl2 so I suppose that's it. Ummm I'm guessing it's crappy wiring in the house then, nuts! Is there anything I can try to find out/fix it?

Slingshot by default has 'Interleving turned off - this gives a greater speed at the risk of more errors. When it's on, your ping time drops, but you get less errors.

You can change your Interleving settings here.

Goodluck with the speeds.

Hi folks, well I have done some testing. I tried my old modem (RTA1320) and was getting speeds of 6mbps+. I then plugged in my DSL-G604T modem straight in afterwards and was only getting about 2.5mbps. I checked the stats of the DSL-G604T and am getting a good data rate down stream (7mbps) but when using the speed test it only goes 2.5mbps. So it is definitely the modem, either there is some funny setting which is slowing it down or it is just plain crap. Does anyone have any suggestions?
