Noise Margin 6.6 dB 14.0 dB
Line Attenuation 55.5 dB 31.5 dB

I'm using my 512kbps line. The download become 224kbps. What happened ? Before got flood in my room. Do i need to change my phone line or my modem ?

Phone line. Nothing to do with Streamyx. you need to have a telekom guy to come and fix it. Look at your Line attenuation , its 55.5DB , heck a lot of noise. Certainly you'll face lots of disconnection and slow speed

finally I found that what make my snr margin fluctuate all the times. when I connect the phone line from the socket to the modem directly, the snr margin only fluctuate between 26~27. but when I connect back to the sliptter, the problem happened. but I dont think is the sliptter faulty since I got another spare sliptter to backup, and still same. any other solution?

i think something wrong with mine

but somwhow i able to do speedtest on izzi website and i get about 1500kbps downstream and 700++ upstream, but in speedtest website downstream is more alike the same upstream will stay the same until 100% then it will start to drop until 300kbps++ until the test really end =.= and in tm speedometer i get roughtly 1100kbps upstream and 300kbps++ upstream.

should i ask them to fix it??? gaming is ok.

Added on July 2, 2008, 6:42 pmops... thing juz getting unstable == dc many times juz now for the 1st time the snr margin turn into negative value ==

If your SNR Margin is good you shouldn't be facing any disconnections. Keep in mind as speed increases the SNR Margin will drop by 0.5 dB . That is just for your information. So if TM has capped you at a very high speed , please call them and ask them to cap back. Otherwise you will be facing lots of disconnection and other stuff

Maybe you can email them your modem status and highlight the downstream margin. Hope they understand what you email them though...

Holy Crap , look at your SN Margin downstream its 4dB only and look at your Line Attenuation for downstream. It is horrible , your phone line is having issues. You better do something bout it. You might have to call TM and ask them to replace your line or something like that. It is very very bad !

How about mine? I have tried to use direct connect without the splitter but still get Downstream Line Attenuation above 50 db.
