why??

and why u choose the modulation as mmode??
why not glite??

I got this reading, the best SNR yet in LYN... notworthy.gif

That is the NEGATIVE SNR value!!! -17!!! Sometimes I even get -43!!!
But I never face any DC problem, this will only effect my upload/download activity.
I keep getting DNS error and no activity...
My Aztech 900EB2 modem can survive this low SNR value sweat.gif

Facing this problem since April,2006. Already made 6 reports regarding this.

Finally, a technician come to my house and said, your capacitance 100% (SNR), there is nothing I can do. It takes time to change the line. He added, no one complain in your area, you are the only one, it is hard for him to change the whole cable just because one case.
He also stated that the exchange in the main center ok, the problem occur at the inter exchange near my place.

WTH, nothing they can do? I am paying the $$$ and i get this reply.

BTW, I am staying in Penang, according to the technician, my inter exchange at Jelutong...
*

that their policy,
user /customer can't make anything...

or u can try to ask them about change the phone line also,
when phone line is change to a new one,
hope that new line is ok too for streamyx connection....

u should refer for the first post

SN Margin (AKA Signal to Noise Margin or Signal to Noise Ratio)
Relative strength of the DSL signal to Noise ratio. 6dB is the lowest dB manufactures specify for modem to be able to synch. In some instances interleaving* can help raise the noise margin to an acceptable level. The higher the number the better for this measurement.
> 6dB or below is bad and will experience no synch or intermittent synch problems
> 7dB-10dB is fair but does not leave much room for variances in conditions
> 11dB-20dB is good with no synch problems
> 20dB-28dB is excellent
> 29dB or above is outstanding

i think your modem is in bridge mode,and router as pppoe mode,
then u can try to look on router linksys web managment and see the snr margin

your line quite ok for me, rclxms.gif
for your info,tm capped the port all to get that value of downstream and upstream,

and the speed that u get, i think better u test with speedometer to get the right speed

Downstream SNR = 15 dB.

Higher is better, minimum = 6 dB.

Downstream Power = < 15 dBm.

Lower is better.

Upstream SNR = 10 dB.

Higher is better.

Upstream Power = < 15 dBm.

Lower is better.

Downstream Attenuation = < 30 dB

Lower is better, maximum = 60 dB.

Upstream Attenuation = < 30 dB

Lower is better, maximum = 60 dB.



3.2 ADSL2+

Downstream SNR = 06 dB.

Higher is not better, within range is better = 05 - 07 dB.

Downstream Power = < xx dBm.

Lower is better.

Upstream SNR = 06 dB.

Higher is not better, within range is better = 05 - 07 dB.

Upstream Power = < xx dBm.

Lower is better.

Downstream Attenuation = < 22 dB

Lower is better, maximum = 22 dB (for 10mbps), 12 dB (for ~25mbps).

Upstream Attenuation = < 22 dB

Lower is better, maximum = 22 dB (for 10mbps), 12 dB (for ~25mbps).



Attenuation to Loop Length Conversion

10 dB ~ 0500 m
15 dB ~ 1000 m
25 dB ~ 2000 m
35 dB ~ 2500 m

Since my DS margin is very low(6-7db), I'm guessing my house is located far away from the DSLAM.

After I have report this case to TMNet, then the technician have do the checking to DSLAM.

The technician have told me that the distance from my house to DSLAM exchange is only 3.5KM.

After that, nothing have been changed(still disconnection happen)...
REALLY CANNOT EXPECT SOMETHING MORE FROM TMNut!!!

that problem from TM cable,
they will not change the whole cable just becoz one or 2 users get the problem..

have u try with another modem??how the result with another modem??
