hey man, try set ur modem ADSL (G.DMT) to reduce line Attenuation for better ping latency. i default set autosnese making me line Attenuation around 44.1, after i set manual adsl g.dmt, my line Attenuation drop to 42. ping previously is 112 to kl, but now juz half around 50+ to kl server when speedtest. u can try it and see the different. oh ya. lower line Attenuation means better connection. try to beileve. u can check ur recent line Attenuation and after set line Attenuation db. u can even test at speedtest for the ping. believe or not is up to u all. if work for u den good.

How about G.Lite?

For my case, if I change my Modulation from Multi-mode/G.dmt to G.lite, my Line Attenuation will drop from 31 to 27

for my case i only set to g.dmt alrdy drop. look like it still depends on line

g.dmt drop from 24 to 21. good work!

g.lite further drop from 21 to 19. GG!

from wiki. cause g.lite will lmit ur speed til1.5mbps. so if ur speed exceed 1.5mbps, pls dont set it to g.lite

OK, thanks for the info. My DSL always connected as G.DMT although the router settings is set to Multy Mode.

Here is my Line quality:
SNR Margin 31/22 dB
Line Attenuation 1/1 d

Is it good?

u set it to autosense/multimode, it will still sync with one of the current mode, which is g.dmt/g.lite/ANSI_T1.413/ADSL_2plus/etc, u need to check out what mode it sync to while u use autosense/multimode. there is no "autosense/multimode", it was use for sync with all the available mode.

my line has ping 80+-ms to www.tm.net.my or 202.188.0.133 if i set it to g.dmt/ANSI_T1.413, the ping value would drop to 50+-ms if i set it to g.lite mode. the SNR Margin, Line Attenuation, stay almost the same in all 3 mode.

If I set my line to g.lite, my adsl line cannot be connected, why?

well, same here. When I set the ADSL to a mode other than Multimode... I'm offline.

hello ts,how bout mine? >

SNR Margin: download =30.0 upload = 24.0 db

compare with previous one before i set is around 28 for download and 19 for upload..sorry but i know nothing bout all this..but my connection keep disconnect recently

DSL Status: Connected
DSL Modulation Mode: G.lite
DSL Path Mode: Interleaved
Downstream Rate: 1536 kbps
Upstream Rate: 512 kbps
Downstream Margin: 31 db
Upstream Margin: 23 db
Downstream Line Attenuation: 4 db
Upstream Line Attenuation: 0 db
Downstream Transmit Power: 12 db
Upstream Transmit Power: 4 db

damn.. thanks! this improve my connection problem, g.dmt always disconnect the line...

Ur line condition is too good to even experienced disconnect, might be ur modem? or u wrap the phone wire at a subwoofer or other electrical appliance emitting interference waves that causing ur line disconnect?

weird why some work and some doesnt? anyway i using dlink modem.

is this something new?

The G.DMT and G.Lite Recommendations

all depend on the router/modem chipset and the dslam chipset.
