The 6dB margin suggests you are on ULL gear, not Chorus, as theirs is 12dB. I would have expected a slightly faster downstream sync speed for the 35dB attenuation though. Given the Chorus SAT indicates you would be connected direct to the exchange (if on their gear), midspan injection is unlikely to be the issue. What is the internal house wiring like?

The house wiring is not perfect I guess. The house was built in 70s and I was told by the previous owner that they have re-done the electrics for the house, but I'm not sure whether they touch the comms wiring. Are you able to tell the external speed from the exchange to my house from the modem stats?

stonecolddy: Are you able to tell the external speed from the exchange to my house from the modem stats? Downstream Rate: 5437 kbps Upstream Rate: 978 kbps Note that those speeds are of course affected by any internal wiring. Did you see what the Chorus technician did when they came around? You mentioned earlier they said you wouldn't get higher than 6Mb/s. If they have disconnected the line at the demarcation point, and tested there, then there is about a 10% difference which is almost certainly due to internal wiring.

At 35db you WILL get 10Mbps. Even if there is an active cabinet between you and the exchange it shouldnt matter UNLESS your line is still wired through a port in that cabinet - this should not be the case if the provisioning of your line was done correctly. However, because you have a port from the exchange it should just be jumpered directly from e to d side and midspan injection is not an issue as it is just like a jumper in a normal cross connect cabinet.

well heres what I get, and theres a cabinet 500m up the road, prior to the cabinet I was on the henderson exchange and getting around 2 - 3 mbits. Im on ufb now so the dsl connection is going soon. Line Mode ADSL2+ Line State Show Time Line Power State L0 Line Up Time 00:17:51:00 Line Coding Trellis On Line Up Count 3 Statistics Downstream Upstream Line Rate 12863 Kbps 1176 Kbps Attainable Line Rate 15640 Kbps 1232 Kbps Noise Margin 11.9 dB 12.4 dB Line Attenuation 11.5 dB 5.8 dB Output Power 0.0 dBm 12.8 dBm

stonecolddy: Below is my modem stats, my modem model is Linksys WAG200G. Is the stats normal? DSL Status: Connected DSL Modulation Mode: ADSL2+ DSL Path Mode: Interleaved Downstream Rate: 5437 kbps Upstream Rate: 978 kbps Downstream Margin: 6 db Upstream Margin: 6 db Downstream Line Attenuation: 35 db Upstream Line Attenuation: 9 db Downstream Transmit Power: 11 db Upstream Transmit Power: 21 db PVC Connection Encapsulation: RFC 2364 PPPoA Multiplexing: VC Qos: UBR Pcr Rate: 0 Scr Rate: 0 Autodetect: Enable VPI: 0 VCI: 100 Enable: Yes PVC Status: Up I'd say closer to 10Mbps is possible, flick me an email / PM if you would like a master splitter installed. Fraser 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? Geekzone special price: $150* for master splitter install, normally $200+ through your ISP. Auckland and Waikato areas. *Travel charges may apply. Additional costs may apply for complex installs. I install - Naked DSL, DSL Master Splitters, VoIP, RBI Rural Broadband. Also a dealer for WorldxChange. Need help in Auckland or Waikato?

Just a quick update on this topic as a conclusion to my story. I had coffeebaron came the other day and installed a master splitter, thank you for your work! Unfortunately, the end result was only marginally better. The download speed has increased from 4.8Mbps to 5.3Mbps. So I guess it's really a distance issue to the exchange. The other thing that really bugs me is that my house is two houses outside the VDSL boundary. So I guess I'll have to wait for the UFB to come in place, which according to Chorus, will be installed June 2014.... year and half two go..

I would be approaching someone inside the VDSL boundary and offering to pay for their internet connection, then just get a pair of ubiquity m5's, one on their roof, one on yours and bridge the two.

Something is a miss here. I have seen plenty of examples of connections with 30-ish dB getting 10Mbps. Now that the internal wiring is sorted call your service company and get the line checked out. It is either an imbalanced pair or there are multiples coming off it which need to be removed.

I suspect a poor grade cable feeding the street; worth checking the neighbours though to confirm if speed is similar. I have seen both instances where this is a good as it will get Vs some where there is an actual fault. Chorus has spent $1.4 billion on making their ADSL broadband network faster.

Thanks guys, I'm with vodafone, What requests should I put through to most effectively force them to check the line? I have had a chorus guy came prior to this post actually (sent by vodafone), and he just simply checked the speed and said that's the maximum speed I can get due to distant from exchange.
