Is there a reason why you have your modulation set to G.DMT? This is usually reserved for ADSL2+ customers who have a highly unstable line and have had their connection downgraded to 8Mbps. But your line attenuation is only 26db (Quite low and lower is better).

Even if you are connected through Optus DSLAMs, you can set the modulation to ADSL2 (just not ADSL2+) and not suffer from port lock ups. You may want to give that a go and re-post the Modem Status (in particular, note if your Line Rate values increase)

OK. The ADSL2+ modulation has greatly improved your sync speeds (up from 6144 to 14663) so now it is simply an issue of the slow speeds.

Bear in mind that testing speeds during off-peak times, especially around the commencement of off-peak, is not a good idea because many P2P applications are scheduled to commence downloading around that time. So the network can become fairly congested and inhibit download speeds.

Could you perform one last set of speed tests during peak times, preferably mid afternoon? Also, try http://www.speedtest.net once and select whichever server it recommends for the tests. Another good international and transparent speed test might be http://media.labs.live.com/All/Video/Photosynth-320.wmv (8 Mb video download). I can regularly get speeds in excess of 300KB/s on this link. Continuing slow speeds (i.e. sub-1.5mbps) will probably warrant a line check by an Exetel, especially considering your high sync speed.

Hi RedTail5

please download one file from each of the sites below at the same time and post the results for each sites.

nvidia.com
apple.com
microsoft.com

If you know of any other international sites you can also use them as well. Just make sure you run multiple sessions to different sites.

Downloads from nVidia, Apple and Microsoft all average around 450kb each, meaning each downloads speed is 450kb each, still downloading from some sites at 10-30kb, sites like filefront only gives me 15kb, even for i filesharing site i don't think my slow speeds are normal...

Unfortunately, if you are able to sustain 450KB/s per file, especially if these speeds were tested simultaneously, then it demonstrates you can sustain high speed downloads from selected sites and so it suggests your Exetel connection is performing adequately.

If other selected sites perform at slow speeds there may actually be a bottleneck outside of Exetel's network. Maybe post a tracert to filefront to see which hop is responsible for the bottleneck.

...and in particular, the cogentco.com hops as hop #6 is the one responsible for most of your ping delay. I assume that similar tracerts to apple.com, microsoft.com, etc show a much lower ping delay?

Yeah, tracerts to microsoft, apple and nvidia gives a much lower ping delay, but now when i download of filefront i am getting a usable 70kb/s, after switching from USB connection to ethernet connection...

Hmmm... for some reason now wen i do a speedtest @ www.speedtest.net i get exetremely fast speeds all of a sudden i just hope these speeds can last :shock:
