Anumber of "speed" complaints have been related to incorrect modulation type. The following suggestion for ADSL1 8192/384 services resolve most speed complaint:

- For high speed ADSL1 customer on "8M" profile, you should use g.dmt as your correct modulation type

Your line speed is 6.28 Mbps (6283 kbps).
Your download speed is 785 KB/s (0.77 MB/s)
it made work 10x better + my online games been running better too.
try it out.

That was 6 weeks ago. That thread would have been archived and deleted by now

Well, why was the thread bumped up? o_O (I didnt realize the date because this thread was at the top and assumed it was recent)

Is the Light bulb shaped threads a sticky?

Yes. Perhaps this thread was stuck to show how modulation and MTU optimisation can improve speeds. Not sure.

Are you still experiencing slow speeds? If so, you probably want to continue your post / the thread at http://forum.exetel.com.au/viewtopic.ph ... 26#p211126

Yes I will keep my posts about speed issue's within that thread. It is annoying that there is no where on the forums showing what each icon/symbol means.

By this do you mean your sync stats in your modem, or your account stats in the user facilities? If you haven't already done so, you should power cycle your modem.

Well, that test showed 1.13Mbps, which is already above 512kbps, so the change appears to have gone through. I would suggest you avoid ozspeedtest.com as it can very easily give a low speed reading. Try speedtest.net instead (which will also test your upload speeds), or even better download a file from mirror.exetel.com.au to test download speeds, perhaps even combine that file download with other, simultaneous, downloads from each of microsoft.com and apple.com just to see what sort of maximum downloads speeds you can obtain in aggregate. It is best to test these speeds in afternoon / early evening times otherwise network wide P2P traffic may impair the results.

hey! thanks for replying! :D
i'm a bit confused cause i'm kinda new to this.. :oops:
i meant on the user facilities :wink:
so does that mean that it has been upgraded then? cause i was on 512down and i have upgarded to 8192down which is a dramatic increase and it feels the same..
is it supposed to be like that?
thanks

No. Make sure you have power cycled your modem, then try the alternate speed tests I outlined in the post above (best to wait until tomorrow afternoon though as the speeds may have improved by then and you will also avoid any issues of congestion that can occur during off-peak speeds). If you are still getting slow-ish speeds tomorrow either post the results, and/or email residentialsupport@exetel.com.au to lodge a slow speed fault
