which as it happens is today :) is the 2.6Mbps i got when i first plugged in my Siemens Speedstream 4200. As with every modem I've tried on my line they all start out with a hiss and a roar and after about a fortnight they start syncing slower and slower. So far its been down to 192Kbps :( .. I have rung Orcon multiple times to try and get it sorted and we've done everything from replace line filters to replace the modem. It seems to be that after about a week or so of really good sync speeds everything starts to turn to custard im never able to hold a consistent sync speed its up and down more than a yoyo more down than up though ... here's a list ost of things I've tried

1: replaced line filter (there is only 1 phone jack in the house) x4

2: replaced Dynalynk RTA1320 modem with a new one

3: replaced the Dynalynk with a Dlink 502t

4: tried my friends siemens speedstream 4200 ( got a much better sync 2.8Mbps)

5: bought a speedstream 4200 (all was well for 2 weeks)

6: orcon ordered a change of port worked for all of three days then back to custard :(

from all that has been done above i can only think that somewhere between my phone jack and the exchange is nackard.

I'm approximatly 4.3KMs from my exchange and i get a 47db ~ 50db attenuation with a variety of snrs ranging from 8.5db through to 12.5db ( i assume in this case higher is better ) i have had telecom do line check and they say its fine but i doubt that because even making a phone call the line is noisy i'm just plain outta ideas here folks anything you can think of to try would probably be greatly appreciated

Sorry to hear that, and yeah happy birthday to u too, a little late. Sounds like it is the line in the house if you say it is noisy. One of my clients had to re wire his house, from the street. Unfortunately you may have to look at the same thing.

I got a similar problem with worse results. Living 2.8km away from the local exchange and max sync rate I ever got was 512kbps. I think in my case splitter is the problem.

thanks for the birthday wishs guys much appreciated

@ sti at that distance why are you using a spliter what modem are you using and what sort of spliter are we talking about FYI if it just the type you plug into the wall jack and the modem plugs into it then you might try taking it out and plug the modem in without it thats what an orcon tech sup guy asked me to do and i got a lot better conection (untill things went to custard again after a week) but worth a try though

just read your other post ok well

Downstream Line atenuation:

41 db

at 2.8 KMs from you local exchange is rubish either your on some very old lines or your house is on a pair gained line (bit like the old party line) whereby two or more houses share a line and use a differant frequency so with more houses sharing the line equals less frequency range per household which equals less bandwidth for your dsl

Well so far so good since seeing some telco guys working on what i can only assume was the telephone cables at the end of our street, my conection has been a stable 2400Kbps. Still a lot less than i know my line is cappable of giving me but atleast it's better than i was getting Smile i'd still like to see closer to the 3200Kbps i was getting last year but i probably wont and i'm not holding my breath waiting for cabnetisation to happen anytime soon read (october 2009 maybe)

SNR: 7db
Attenuation: 49db
