Ive been having a few speed problems since I moved into my new house.  Im with Telstra but I dont think the ISP is at all relevant.  Im thinking I have a line fault still to some degree.  It all started as follows:

Moved in - huge humming on the phone line to the point where I couldnt use it for more than about 3 mins without getting a splitting headache.  Internet was syncing ok at around 1200/150ish..  After three weeks of waiting and ringing and whatnot they fixed the line mostly (still a little humming but its within my acceptable level since I use VOIP for all my calls anywaya!).  When fixed the internet jumped up in speed to around 2200-3000/180-760ish.  Ive done speed tests and the upload definately seems to be working at the rated speed (uploads at around 60k, downloads at 200-260ish). 

Now the strange thing is it normally only connects at around 150ish.  It wasnt until I stuck in a new modem (Dynalink RTA1335) that it started connecting faster  - dont get me wrong, I would much rather it be faster than slower!  The speeds just dont seem to really be in sync in any way like I'd expect them to be! 

These are the stats from the modem:







<!-- hide
var linestate='Show Time';
var mode = 'ADSL2+';
glbmode = mode;
document.writeln("<td width='80'>" + mode + "&nbsp;</td>");
// done hiding -->







<!-- hide
if (glbmode == 'ADSL2' || glbmode == 'ADSL2+'){
document.writeln("<td class='hd'>Line Power State</td>");
document.writeln("<td>L0&nbsp;</td>");
} else {
document.writeln("<td class='hd'>Latency Type</td>");
if ((glbmode == 'ADSL2' || glbmode == 'ADSL2+' || glbmode == 'READSL2')){
if ('32' == '1')
document.writeln("<td>Fast&nbsp;</td>");
else
document.writeln("<td>Interleave&nbsp;</td>");
} else {
document.writeln("<td>Fast&nbsp;</td>");
}
}
// done hiding -->

Statistics Downstream Upstream
Line Rate 2198 Kbps 762 Kbps
Attainable Line Rate 2836 Kbps 762 Kbps
Noise Margin 12.6 dB 12.2 dB
Line Attenuation 59.0 dB 35.5 dB
Output Power 16.7 dBm 12.4 dBm


Is it really worth my while ringing up and seeing if theres a fault or does this look and sound sort of correct.  Ive moved roughly 500m down the road, was getting an 8mb connection before. 

Any suggestions would be good.

its a bit low , the Line Attenuation of 59 means you will never get more than 4000 on a good day ,3000 to 3500 is about normal. so you should get more than you are getting




Common sense is not as common as you think.

generally speaking humming points towards a battery or earth fault, which most likley a cable issue, so when they "fixed the fault" i presume they sent someone out?

Thats what I thought the line fault was.  They reckon they had 3 people look at it but no-one physically came to the house.  Might still make them come over and see..

Just remember that 500m down the road doesn't necessarily mean that you're connected to the same exchange or cabinet ...
