ATT DSL keeps dropping connectionWhat would cause my ATT DSL Internet to randomly drop connection? This random connection drop occurs sometimes once a day or at least several times a week! I/we use our Internet every day and for many hours every day. How can I go about finding the culprit, or at least understand the problem? Please keep any explanation simple for I am a NON expert average consumer/user.
I have ATT DSL PRO with Speed Stream Modem and Asus RT-N66U Router. Everything is set correctly AFAIK and generally works well MOST of the time, with the exception of "out of the blue" unexpected random dropped connections! This then requires a re-start of Modem and Router by turning off each (button(s) in rear, then turning back on Modem first, followed by the Router after the DSL solid green light appears on front of Modem, in order to complete the "Ethernet" connection light on the front of Modem. Finally after the "Internet" and "Activity" light starts blinking and syncing, I get all 4 steady green lights on the Modem and Router shows normal lights, I am ready to go again!
I have updated the Firmware of the Asus Router to the latest revision recently, and can NOT find anything amiss in the Router`s software Interface or settings. I have not looked at or changed anything in the Modem`s settings, software or Interface since I first received it from ATT many (?) years ago.
Thanks for any insight into this issue. |

Which Speedstream modem version?
Your description indicates that the modem is making the PPPoE connection, correct? Have you determined if drops are due an interruption of DSL sync or simply loss of the PPPoE connection?
Can you access your modem stats? |

Hi and thanks for your reply
Modem is SpeedStream 5100
On Modem`s "Internet Connection Configuration" page it says: PPP on the Modem (Public IP for LAN). Also says Protocol PPPoE On "PPP Location" page it says: PPP is on the modem. Under "Home Network Configuration" it says: DHCP Lease 0 Days, 0Hours, 10 Minutes.
How do I determine "if drops are due an interruption of DSL sync or simply loss of the PPOE connection"?

With the power LED, there are five LEDs, right? Then you have a 5100b and checking the modem stats: » AT&T Midwest/Ameritech FAQ » Where are the Line Stats in a 5100b or 4100? would give some info about the drop causes. |

Is this "normal" for PPP on the Speedstream 5100B Modem, and PPPoE Protocol? Connection is UP, with 4 solid Green lights (Activity light blinking) |

Can you post the contents of the log page? |

Thanks Here you go, attached as a .txt file. I hope this will help determine what the problem might be, cause I have NO idea how to interpret this modem log. |

The log looks okay....... I would like to have a look at the dsl line stats, click the statistics button and paste the
Modulation Max Allowed Speed Signal to Noise margin Line Attenuation CRC Errors

Ohhhh that looks bad... Have you rebooted the modem? Have you tried connecting the modem at the nid when it's like this? |

By rebooting the modem do you mean turning off and then back on (button in back)? If so yes, when I have dropped connection. No I have NOT "connected the modem at the nid when it`s like this?". If this is a "bad" indicator, how is it I am still connected online? |

Just turning the modem off then on is a reboot said by mattrixx:If this is a "bad" indicator, how is it I am still connected online? The page image makes me think there is no internet connection. And I still would too see the dsl stats before offering any suggestions I don't have access to the modem so I can only speculate about what is occuring/ |

Thanks, but I can assure you I DO have an Internet Connection (at this time), but one last thing to look at might be this screenshot of a portion of the modem`s "Technician Readout". |

said by mattrixx:Thanks, but I can assure you I DO have an Internet Connection (at this time) Ok, The log indicates that the modem or router is slow to acquire the public ip address when the connection goes down. I suggest that you try changing a setting on the modems connection configuration page. At the bottom of the page select No, use private IP address And save the change this should reduce the amount of time the internet is down I won't tell you that replacing the modem will stop the internet connection drops. Something is not right with the modem you should consider replacing it. |

OK, thanks again wayjac.
After saving the "No, use private IP address" setting, wouldn't I necessarily have to provide a private IP address?
Also, so as I understand it, this "change" is just going to reduce the time I`m back up online automatically, when and if the connection drops, without actually physically rebooting the modem (and Router) ?

If you are still connected to the internet without the modem ever showing no DSL sync stats, I'd say your modem is in the process of dying. ... but it doesn't look as though sync losses are dropping your connection.
The DHCP server at times isn't updating the modem and the Smarttimeout is invoked dropping the connection. |

No, you will not need to provide a private IP address The modems dhcp server will do this automatically said by mattrixx:Also, so as I understand it, this "change" is just going to reduce the time I`m back up online automatically, when and if the connection drops, without actually physically rebooting the modem (and Router) ? I'm thinking this change will allow the modem to fully reestablish it's internet connection without a reboot of the modem or router. I think this will help because the log indicates the public ip address is not renewing as quick as it should. Here's some example messages: Last DHCP Server message repeated 206 times. Last DHCP Server message repeated 2860 times. |Last DHCP Server message repeated 12 times. |Last DHCP Server message repeated 567 times.
The dsl sync speeds are normal The dsl is set to fastpath |

I don't know if this will help your problem, but your modem's firmware is way, way out of date: » AT&T Midwest/Ameritech FAQ » Where can I get the 1.0.0.53 firmware update for the 5100b? The problem is that FAQ doesn't have a working link to the newest firmware. Edit: This FAQ has a link to the upgrade ZIP file: » SBC DSL FAQ » What is the latest firmware update for my 5100B?Cut-n-paste the complete ZIP and help links into a new tab or window in your browser to access them.

I don't think updating the firmware is something that should be attempted with a "dying" modem it could kill it, left as it is it's working.
I can provide a copy of the firmware
There is a chance the router is the cause of the delayed exchange problem I say this because the modem is attempting to allocate the ip address but the router won't accept it. |

If the OP could get the modem to be regularly showing the DSL stats, then there shouldn't be any problem with the upgrade. I think letting the router make the PPPoE connection might solve the drop problem, but then the modem stats aren't readily accessible unless alternative methods are used: » SBC DSL FAQ » How do I access the modem GUI thru a router - advanced methods? |

I seem to be getting this too but I have 5100 4 led that one has no GUI right??
IS there away to get att to give me a new one for free? or should I use my old wirespeed? I also have a 5 led 5100 that I will try.
I may want a IPV6 one soon. |

You would have to buy a replacement DSL (not one of the ADSL2+ models) modem from AT&T's online store or buy a used AT&T modem from eBay or Goodwill.
Try not to spend a a large amount for a replacement just in case AT&T forces you to switch to ADSL2+ or UVerse which would obsolete any DSL modem you have. |

Thanks d_l and wayjac for all your help in this matter One last question: Will I be able to use my Asus RT-N66U (expensive nice) Router if I should make the switch to UVerse, which sounds like what ATT wants legacy DSL users to do? |

Some of those non-AT&T modems at brick and mortar stores will work with AT&T DSL, but their DSL stats are crazy wrong. So if your DSL line sync acts up and you check your stats, you can't really believe the numbers.
The Actiontec DSL modem comes to mind if I recall correctly. |

OK, exactly what "simple configuration changes" do I need to make to my Asus Router, to include it (and all it`s nice features) with a U-Verse Connection, with it`s required proprietary "Gateway"? |
