| DSL Disconnections at Night, please help meRecently my DSL connection gets really weird.
About 7:00 PM each day, for some reason the signal on modem starts going in this sequence:
1/ Flashing red ,then flashing green on "DSL" spot
2/ After about 5 minutes of flashing red & green, both "DSL" and "Internet" go back to solid green.
3/ But not enough 30 seconds after that, the "flashing red & green" game continues, which make me really frustrating because each time I re-open Firefox or IE again, I can't even see... the homepage to show up.
This problem persists throughout the night, until about 7AM next day, everything goes back to normal (but the speed is really slow)
Extra notice is that during the time that my connection starts to have the issue (which it is right now), if I tried to use my cell phone to call my home phone, something called "Number busy" showed up. And if at that same time, I pick up the home phone to hear it, the noise is really and especially loud inside for about 10 seconds, and then dead silence.
As for statistical info, this is the picture of my connecting information (of course when both lights are green for 30 seconds)

Please help me! I tried all aorts of self-troubleshooting, including: check the filters, check the main phone line, etc... yet the problem still continues. I called AT&T tech support 2 times, yet after 2 times that a technician comes to my house, the problem is still there. :(
Thank you in advance |

kudos:7 | You should report this to AT&T as an evening voice line problem rather than a DSL problem. Once the voice problems are corrected by voice repair techs, then there is a good chance the DSL will be fixed as well.
It sounds like there some sort of light (nearby failing mercury vapor or sodium, CFL porch light controlled by a daylight sensor, etc.) that is coming on after dark and affecting your DSL with its electrical noise. There maybe something about your phone line to make it extra susceptible to any electrical noise nearby. The light powers off in the morning and your signal is just fine.

| Does this sort of "light" has anything to do with the security system? Because I know the landlord installed a set of security lights all around the house. |

That might be the source of interference. |

Although the Noise Margins during both the Connect and Disconnect times are pretty bad, it is interesting that the Downstream Noise Margin is higher during a Disconnect period; this is not what would be expected if some noise source was active. |

kudos:7 | If the modem had just re-connected after being disconnected, it is very likely that the noise margin would be higher as the modem re-trains to the most current noise conditions.
