New 4Meg line drops !!!! :(

Live in Garsfontein Pretoria but checked now and line is back at 7042 ?? WTF !!!

Lets see how long i cabnn keep this up she did reset my port earlier maybe it made a diffrence gonna get download speed test and post here
 
LOL dropped again to 4096 WTF TELKOM

gona give em a call now now again 5th time today !!!!!!!
 
hahaha they toying with ur emotions.. good luck with the phone call. i held on and listened to that music for 53 mins the other day before i hung up... 53 MINUTES
 
I have been struggling with the DSL at work for 2 weeks now. Just one day, suddenly out of the blue our line started dropping every 10-12 minutes, sometimes shorter intervals!

It got so bad it dropped about 61 times before lunch the one day!

I have logged 5 faults at telkom over the last 2 weeks, but you guessed it, still have the same problem - I must say it improved slightly, but not enough to download your mail!

I feel like I'm on the verge of loosing my job as a result of this line. Everybody in the office needs to use 3G to send and receive mail.

I just asked them now to drop the sync rate to 3meg and we'll see what happens. Should the telkom techies know this stuff and try it?

Apparently the only thing the techies do know is the following line - "Sir, have you tried changing your router?" :mad::mad::mad: The answer is "Should I smack you over the head with a shovel now or when you leave?"

lol dude drop your line speed also check your SNR and attentuation
 
Downstream Upstream
SNR Margin (dB): 12.8 12.0
Attenuation (dB): 44.0 21.0
Output Power (dBm): 8.9 10.9

There is your problem! your SNR is at 12.
The higher you synch the lower your SNR drops and your on just on the edge of having it stable.

here is my current stats

Downstream Upstream
SNR Margin (dB): 21.6 8.0
Attenuation (dB): 42.0 19.0
Output Power (dBm): 12.4 8.3
Attainable Rate (Kbps): 10592 628
Rate (Kbps): 4096 512
K (number of bytes in DMT frame): 129 17
R (number of check bytes in RS code word): 0 0
S (RS code word size in DMT frame): 1 1
D (interleaver depth): 1 1

OMG!!!:eek:

Edit: Telkom mailed me back within 7min from reporting the fault (YES YOU HEARD ME - SEVEN MINUTES) saying that they dropped my sync speed as requested.

This must have happened while posting the previous message via 3G.

Back on the DSL now, we'll see what happens.

AND before I forget - the one telkom technician which did the line tests told me there where NO noise to speak of on the line :-/

doesnt mean im gonna get it though :P
*twiddles thumbs waiting for 8mbit*
 
Is this better?

What should this be?

Downstream Upstream
SNR Margin (dB): 11.3 12.0
Attenuation (dB): 44.0 21.0

This is at 3meg sync speed.

thx

dude my SNR is also at 12 ??? so basically we looking at a line drop then ?
 
Can someone give us the spec for SNR and attentiuen on the line at a 4Mb line ??
 
if you reach 6 you are going to get a disconnect (sync drop).

if you have a line problem you can get SNR variations that makes a 5-10 SNR value drop easily.

As per Mineer's post http://mybroadband.co.za/vb/showthread.php?t=186156

Signal-to-noise ratio
Signal-to-noise ratio (often abbreviated SNR or S/N) is an electrical engineering measurement defined as the ratio of a signal power to the noise power corrupting the signal.
In less technical terms, signal-to-noise ratio compares the level of a desired signal (such as music) to the level of background noise. The higher the ratio, the less obtrusive the background noise is. The concept can also be understood as normalizing the noise level to 1 (0 dB) and measuring how far the signal 'stands out'. In general, higher signal to noise is better; the signal is 'cleaner'.

Attenuation Rate
Attenuation is the gradual loss in intensity of any kind of flux through a medium. For instance, sunlight is attenuated by dark glasses, and X-rays are attenuated by lead.In ADSL the signal is attenuated by length of copper lines. Attenuation is mesured in db or noise. The more noise the weaker the data signal
In general, lower Attenuation is better; the signal is 'stronger'.


Heres is my table of comparisons
SNR:

6dB or below is very 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 little or no sync problems
20dB-28dB is excellent
29dB or above is outstanding

Attenuation:

20dB and below is outstanding
20dB-30dB is excellent
30dB-40dB is very good
40dB-50dB is good
50dB-60dB is poor and may experience connectivity issues
60dB or above is bad and will experience connectivity issues

Dude i think everyone should thank MrNutz that is the most useful thing i have seen the whole time i been here going to check at home on my router

DUDE YOU ROCK

sweet
 
I just got my sync speed reduced to 2meg

I know have the following stats

Downstream Upstream
SNR Margin (dB): 16.0 12.0
Attenuation (dB): 44.0 21.0
Output Power (dBm): 10.1 10.2
Attainable Rate (Kbps): 6304 872
Rate (Kbps): 2048 512

I am still waiting to see if this will solve my problem
