Hello,
I have uploaded some screenshots of the results I got after I ran some diagnostics on my 4096/512 ADSL line.
I suspect that too much noise on the line causes re-transmissions which in return lowers my effective downstream speed for TCP traffic. I have measured a downstream speed of approx 2mbit and it is supposed to be around 3.7mbit.
Could you please tell me if I am right?
In my router I see that the line attenuation (downstream) is above 60dB and the SNR is sometimes as low as 3dB.
My ISP keeps on saying that they measure 4096/512 on my line, but my diagnostic tools says otherwise.
I look forward to receiving some comments. Thank you.
