Slow TELSTRA ADSL2+ with NETGEAR D6300

[reneeflips]

Hi,

I recently (Feb 2016) got a new Internet connection with Telstra BigPond, which I assumed was ADSL2+. After getting SLOW speeds (around 2.25Mbps) I called Telstra and they told me I was only on ADSL, however an ADSL2+ port had recently become free, so they upgraded me. The speed has not changed, still averages around 2.25Mbps.

I'm using a NETGEAR D6300, which I've used at a previous address with Telstra ADSL2+ and it worked fine.

I've spent HOURS on the phone to Telstra, no word of a lie 10+. They've done checks, line flushes and tests etc. on their end and I've done everything they've said and everything I've read in forums. NO AVAIL!!! Firmware is up to date, I've rebooted both the modem and my laptop (many times), hard reset the router, adjusted the WAN MTU settings (suggested in one forum) and I have been doing it via Ethernet cable.

Any advice would be appreciated, before I have to get the Telstra technician to come to my house $$$$$

Thanks,

Renee

What are the line stats that the modem is getting?

Line Speed, Sync Speed, Line Attenuation, those sorts of things, they will be in the modems control panel...

They will help give us a better idea of what sort of speed you could be getting...

Also when did you get it changed to ADSL2+, as that change can take up to a week to go through... (minimum is 4 business days due to gov. requirements).

Hi,

The changeover from ADSL to ADSL2+ was initiated last Wednesday. So 4+ business days have passed.

I've also been checking the speed on this web site:https://www.mybroadband.communications.gov.au/speedtest.aspx

With that Line Attenuation it is unlikely that you would expect any speed over maybe 4Mbps on the sheer distance from the exchange that that would suggest... That is with everything else being perfect...

That upload speed does make me wonder if it has actually changed over as even over distance the loss of speed on upload tends to be significantly less...

Also do you have a line profile on the service that you know of? They often apply line profiles when there is noise on the line as it can increase stability, but it does tend to reduce the speed you obtain.

noise ratio is almost spot of target (6db)

Doing a rough check with an attentuation calculator

Enter your Downstream attenuation (dB)
Cable Loss (dB/km) – Default 13.81
Attainable Rate (ADSL1) – kbit/s	4270
Attainable Rate (ADSL2) – kbit/s	4421
Distance to exchange (Meters)	3802

Due to the distance from the exchange there is not a lot of difference between ADSL and ADSL2+ in terms of speeds. The statistics you have displayed don't cover the technology/dsl type but based on upload you may have not been changed over yet

Take about 20% off Sync Speed and theorectically you could be getting about Max 3.6Mbps on ADSL2 and 3.4 on ADSL1. It is a bit of a tough call as to whether Bigpond Tech Support can actually assist as all this is based on perfect conditions and most of the copper, unless it is a brand new estate, is far from perfect

Thanks for your responses.

The guys at Telstra (tech support) said that I had already crossed over to ADSL2+ but here's hoping I haven't so I can get a little bit more speed at least.

If that's not the case; I am living in a very old suburb, so perhaps the slow speeds are down to a combo of distance from the exchange and old wiring? Damn it, fingers crossed the NBN comes to these parts soon.

Kind Regards,

Renee

At that sort of distance the difference between ADSL1 and ADSL2+ is negligible... the only real difference at that distance is on the upload rather than the download...

Wiring could be playing a part but to be honest, I would say my educated guess is that the speed issues are primarily based on the distance and maybe with a little help from congestion or line quality or some other combination of other factors...
