I'm guessing the phone line (or DSLAM) is longer than the usual (3+km). Ionosphere height increases at night causing signals to go farther and thus causing crosstalk, ADSL frequencies are similar to MW radio, the effect is only possible with very long lines, that and probably crosstalk from heavy users during these hours. Are your phone wires outside (street post) or under ground?DG wroteWasn't sure if I should post this under "Internet in Lebanon" or here. But, since I am an Ogero subscriber I decided to try here.
My problem is the following: When I first turn my modem on in the morning my parameters are:
Data Rate: 4,096kbps
Max Rate: 7,700kbps
SNR Margin Down: 18.5 dB
As soon as the sun sets everything drops to:
Data Rate: ~3,650kbps
Max Rate: ~3,700kbps
SNR Margin Down: 9.5 dB
As you can see the SNR Margin drops by quite a bit and the modem has to resync so I lose connectivity.
Now, I understand that at night DSL is more affected by interference such as radio waves, ppl at home using more appliances, etc... but is it normal to see the SNR drop to half the original value ?
Post your full stats, especially attenuation.
