shouldn't i be syncing at a faster speed?

Post by skyrex » Tue Apr 01, 2008 6:31 pm

just got upgraded to DSL2+ this afternoon (WOOT!)
but when i updated my rooter to connect to exetel svc, it shows the following:

Modem Status: Connected
DownStream Connection Speed: 10544 kbps
UpStream Connection Speed: 812 kbps

should it be faster sync rate than that? i was under the assumption that DSL2+ means possibly as fast as 24000 kbps?

have done speed test and it showed down spds of ~8mbps.
i live <800mm from the exch, and there is estimated 1200m+ of cabling between me and it...

i havent checked filters yet just though id throw it out there because to my thinking its not a filter issue...

also using a Netgear DG834Gv3 :oops:

Those sync speed and speed tests are fine for ADSL2+

Your assumption is completely correct...ADSL2+ speeds are "UP TO" 24000kbps.

Filters may improve your speeds a little, but there is nothing wrong with your stats as they are. They place you in slightly above average in terms of ADSL2+ sync speeds

ok cool thanks for the info.
i wasnt hugely worried, im stoked with the speeds im getting its a MASSIVE jump to go from 512k and on top of that being shaped back to 64k for the past 48hrs :D

warp speed engaged!

10mbit sync is very fast. You would have to be pretty close to the exchange to get that.

I'm 4km away from my exchange, right on the boundary actually, and I get 4.5-5mbit download sync consistently. And I am happy with that.

What's really annoying me is there is another exchange only 1km away from where I live but their ports are full :(

Just on this. Are EXETEL ADSL2+ speeds up to 24000kbps?

I was under the impression it was and i'm sure you used to advertise it as such but i've never been able to get such speeds (I'm within 300 metres of the exchange)

Yet looking at my plan today it said I was on a 18000/900kbps plan.

What gives? Do Exetel only allow a total speed of 18000kbps download? Or am I on an inferior plan?

If you can get near or above 18000 kbps on ADSL2+ by all means take it.
I remember reading a report half a year ago (APC mag I think) that a modem right next to a DSLAM (think less than one metre) only achieved speeds of 19000 kbps.

Good luck. :)

ADSL2+ technology can theoretically achieve 24Mbps. Practically however, the real-world upper limit is more like 18-19Mbps (on any ISP). So Exetel changed the advertised maximum speeds to simply reflect this real-life maximum as opposed to the hyperinflated, theoretical maximum.

I wouldn't worry about those rates. I live about 600 metres from my exchange and get 19Mbps down and 824Kbps up.

90% of the time my downstream sync speed is not the limiting factor -- very few servers will download faster than 10Mbps.

For P2P, your upload speed is very important, and yours is good.

so in that case if we are on a 18000/900 plan shouldnt our modem/line be syncing @ 18000/900 and not 10544/812, then giving us the actual down rate of "X" mbps depending on distance?
again im not hugely fussed, im loving the spds im getting however if its something like my modem thats just not upto the task of handling DSL2 sync speeds im happy to replace it.
sorry for the nub questions im still new to the DSL2 side of the interweb with line attenuation etc etc that i never experienced first hand on DSL1 :oops:

You could reason things this way, but no. ADSL technology is capable of between 1.5Mbps and (let's say) 18Mbps. Your individual phone line however has a different and specific maximum that your modem measures and determines (i.e. "Attainable Line Speed"). It then chooses to sync at a speed slightly lower (i.e. "Line Speed") in order to have a small buffer for fluctuations in noise.
