First post, I need help with this values

[Abdelsabour]

HI guys,
This is my first post to this great forum,

I really suffering from a big problem ( speed gradually decreased from 5 mbps to reach 512 finally ) with my adsl and need help to understand the problem and what is the best solution.

Is this is my adsl properties, but the provider tell me it's a temporary solution :-

Hi there
I'm not an expert but have a little experience with my own setups.

You are currently syncing at 4Mb and the max downstream rate of 8Mb+/- means you are well within range of what is available.

Your SNR margin is somewhat low, which may or may not be a culprit(or rather a symptom), if you are experiencing line problems.
Upstream noise safety coefficient (dB):
5.5
Downstream noise safety coefficient (dB):
10.3

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

Have a look at hardware first : remove filters and splitters etc. Test another router and keep an eye on your stats to see if anything changes. After you've done all you can on your side, log a fault with the ISP or Telkom. They do generally help as long as you prod them enough.

This is my values after removing splitter and phone and connecting router directly from the phone line

As shown your stats have improved somewhat.

With these stats you should be able to have a good stable connection for most tasks online.

The SNR value is ok but still not great.
Upstream noise safety coefficient (dB):
7.5
Downstream noise safety coefficient (dB):
15.7

If the line is still unstable or the connection drops, just double check your hardware (test another router if possible), make sure no network cables are damaged etc. Then the only option is to report the fault to the ISP or Telkom.

Your Line Attenuation is excellent which means you are close to the exchange and are getting a strong signal.
Based on that you should be able to push your speed even higher if required.
Upstream line attenuation (dB):
13.3
Downstream line attenuation (dB):
20.8

Let me know how the line is now. Regards
