I am writing regarding the terrible speeds which I am receiving on my ADSL2+ connection. I am connected on the 20gb business CallPlus plan, so the line is not throttled at all from their end. However, I am consistently receiving around 260-320kbps Downstream and 380-420kbps Upstream. As you will know, this is much less than the theoretical line speed for ADSL2+ and it is very disappointing. Sometimes it barely seems better than dialup (which we have, unbearably, used for the 10 years it took to upgrade our exchange).
Here are the details about my connection, and the summary statistics from the router:
Connection: ADSL2+ 20GB CallPlus Plan
Router: Netcomm ADSL2+ NB6Plus4 (FW: 3.66t)
Phone jacks: 3; all with filters
Phone lines: 2; ADSL2+ on the secondary
Line Mode ADSL2
Line State Show Time
Line Power State L0
Line Up Time 01:18:08:42
Line Coding Trellis On
Line Up Count 3
Line Rate 361 Kbps
Attainable Line Rate 392 Kbps
Noise Margin 10.4 dB
Line Attenuation 76.5 dB
Output Power 13.1 dBm
Line Rate 413 Kbps
Attainable Line Rate 346 Kbps
Noise Margin 10.6 dB
Line Attenuation 46.4 dB
Output Power 12.4 dBm
I really hope there is something that can be done to improve the speeds. It is so very frustrating to know that it is capable of so much more, and the results are infact so poor.
Any suggestions or help would be appreciated. Let me know if any extra information would help.
