What makes my SNR keep changing? And It seems the speed also affected. Called TM, they said its not possible.

my download snr margin is around 26-31, but still always disconnect, what's the problem?

If anyone reading this, here's my problem:

Currently using modem dsl500T and frequently modem need resync but it won't disconnect. It mostly happend at night. The resync sometime might take up to 15minutes.

Snr Margin: DownStream=6, UpStream = 16
Attenuation: Down=58 Up = 63
datarate: Down = 1536, Up = 512

FYI, the telephone line already re-layout by telekom recently (from telekom pillar to my roof). I know you guys see the figure i mention will surely say my house phoneline problem but i even tried directly connect to the telekom main line---> personally plug a new cable from my roof direct to my modem without going through phone. It give same snr/attenuation value.
I called up streamyx and they say i have no disconnection and cannot log call. I think this is becoz my modem resync (but not disconnect --> no ip change) and they see as no problem.

So, what can i do? Do you guys think i should screenshot my modem line status and email them? Any advice will much appreciated.

I have same problem as you, the only difference is that everytime the modem resync, I will lost connection and have to renew IP. This is what I do to restore my connection back. Documentation is important because with it, you can use MCMC to force Telekom to REALLY FIX your problem.

First, you make a report at https://tmbill.tm.net.my/iCoMSWeb/external/CreateCaseServlet - make sure you attach the screenshots of your SNR margins with the report. Make sure that you explained in that report that you have done all those 'neccesary' things such as plugging directly to wall socket, not using splitter, using manual dialer etc. this is important. Then jot down the report number.

Everyday, make a screenshot of your SNR ratio and keep it for MCMC documentation.

After a few days, call the hotline and ask for the status for your report number. The operator should be able to tell you what they have done. They may ask whether you have done all the things in their manual, and reply that you have done so. The operator may or may not create a new report number as they passed the issue to the ground technicians.

From my experience, things that they do includes resetting the port, going to the pole near your house or replace the 'pair' at your port. Make sure you check your status every few days to get the latest info. If your case runs like mine, you may get few more report numbers, I got 5 more in my case. Log all the report numbers you have got.

After a month or so and your problem is still not solved, it is time for you to get a rebate for all your problems. Below is a report I have made....



After that, download the complaint form from the MCMC website, fill it and e-mail/fax it alongside with the copy of request for rebate to MCMC. In my case, I've done both faxing and e-mailing it, just to be sure.

In my case and to their credit, within 24 hours, TMNet did contact me and replied that my request for rebate is approved, and it is an indefinite rebate at that. MCMC also e-mailed me to acknowledge the receipt of the complaint. But as I would rather prefer paying full price for a Streamyx connection that does not blink every time it rains or at night than paying half-price for an unstable connection, I still made calls to the hotline.

A few days later, TMNet Rapid Response Team e-mailed me that they have received the MCMC complaint form and told me that they will try to solve my problem as soon as possible. The very next day, a big contingent of Telekom technicians comes to my housing estate and simply rips out all the cabling there and replace it with new ones. For 2 days all the residents there (and also me) do not have telephone/Internet access. But after the service is restored, my Streamyx service is now much better before the problem started. Now my modem sync with the DSLAM at 2048 down/ 512 upload with 30dB local SNR while the attenuation is a crazy value of 0.5dB only. Before this, my values is almost exactly like yours.

Now I have just finished e-mailing TMNet to stop extending my rebate past September 2007 bill. So you have to be very persistent in trying to get this problem solved.

Thanx very much for the great reply, now i know what will be my next step.

Unfortunately, I never do that before.

When my streamyx is unstable, I call them many, many times in a day just to get them work. Finally, they got borred with my call and replace all the phone cable and change my port. Now, the connections is OK.


I am verry free to do that as long as my connections get restore back.

what ip u able connected to?

DSL 504t

SNR Margin
0 Downstream 4 Upstream

Line Attenuation
54 Downstream 26 Upstream

Data Rate
1024/512

Amazingly i can stay connected, but i cant surf anything at this point, so i have to restart my modem so it connects at around 6db until it slowly degrades to 0 and has to restart again, I've tested it on multiple modems and i keep getting the same results. This is even done on a brand new wall socket (I added a telephone socket in my bedroom, and rerouted the house telephone circut so it goes straight to my room after the pole, then into the living hall).

Many, many 1300 88 9515 and emails to customer care later, Im still facing the same problem, with streamyx refusing to send any technicians over to have a check (reason : they still have to monitor the line until they can dispatch anyone) and this is like 3 weeks of constant complaining and emails.

I used to be able to host dota with no lag at all, then around 3 months ago, it would lag like mad during peak hours (12pm-6pm) and everyone would lose synch with me. Surfing international websites have been a pain in the ass with major packet loss. I cant even play online games with my old guild anymore because the insane packet loss and loss synch. Imagine emptying a clip into someones head, and then you die and the server reports 0 hits 0% accuracy.

Update: 1450 today my line totally went down, technician called me up, now it reads

SNR Margin
31 Downstream 26 Upstream

Line Attenuation
5 Downstream 2 Upstream

Data Rate
1024/512

i'm shock, my bt speed everage from 5kps to 20kps, if got local seed, max can get is 60-70kps.

was using Rm66 package, with the same speed once upgraded to RM88, i got 150kps on BT, was soo happy but tat lasted for a week then back to old speed, am i being mis -cap? i tried call them and request for port change ,even email them, all i get is stupid noob response and no help....

Same reply here

Hi guys,

I'm having a funny situation here where I've no problem with my download speed, around 45 - 50kB (RM66 package). But my upload is very bad, I can't send email or upload file to server or send file over MSN. I'm using Linksys WAG200G all in one modem AP.

Does any of u guys have this same problem before? I plug the line directly to the modem (no phone).

DSL Status: Connected
DSL Modulation Mode: MultiMode
DSL Path Mode: Interleaved
Downstream Rate: 1024 kbps
Upstream Rate: 96 kbps
Downstream Margin: 13 db
Upstream Margin: 7 db
Downstream Line Attenuation: 44 db
Upstream Line Attenuation: 15.5 db
Downstream Transmit Power: 10 db
Upstream Transmit Power: 18 db

i'm using the free modem given by streamyx.. having frequent disconnection also..but the DSL and Data light is still ON just the browser not responding, cant sign in msn and cant even open yahoo.com = =

by the way im not using vista, it's XP

That is a problem outside your ability to solve. Just make a report to TMNet about the SNR loss.

Modem Status

Connection Status Connected
Us Rate (Kbps) 512
Ds Rate (Kbps) 1024
US Margin 18
DS Margin 15
Trained Modulation ADSL_G.dmt
LOS Errors 0
DS Line Attenuation 57
US Line Attenuation 31
Peak Cell Rate 1207 cells per sec
CRC Rx Fast 424
CRC Tx Fast 35
CRC Rx Interleaved 0
CRC Tx Interleaved 0
Path Mode Fast Path
DSL Statistics

Near End F4 Loop Back Count 0
Near End F5 Loop Back Count 0

How's my SNR margins and Line Attenuation? I'm getting frequent disruption on connection, especially on rainy days and in the evening around 4pm - 5pm. I use a splitter.

The DS margin is borderline case. May have problems in rainy cases.

Oh yes, the frequent disruption on rainy days. Is there any way to fix it?

Need you all to help me check it out...
My SNR keep on dropping from time to time,hmm...

The first I get connect,My Ds Margin will be around 28~22 and it will just drop to 11 after some time

More often than not, there's nothing you can do. Calling TMNet is the solution, tell them you have SNR loss problem.

Try checking for parallel phone lines in your house, and try connecting directly to wall ,socket.

I oso faced the problem that frequenct disconnect during rainning day and the SNR margin is drop.
