SBC DSL Elite Dallas Area

Same boat with Pro in DFW. Does fine t 2.4 for awhile then I'm down to .45Mbs

The interesting part is that it has been rock solid for 4-5 years ... right at 5.1 Mbps and then about 3-4 weeks ago it started coming to a grinding halt.

On a Friday night, it just dropped down to nothing (13 kbps) so I figured that ATT DSL was doing maintenance. On Sunday, it was still doing it so I called Support ... suspect that it was in India. That is not necessarily a problem as long as the problem gets solved.

Anyway, after rebooting the modem, my LinkSys router, my PCs, etc several times, I finally got them to put in a ticket. The first available time was Friday, June 12th. The Service Tech checked out everything and it was going up and down with his machine as well. Replaced the modem, checked the wires inside the house, the wires to the central office ... could not figure out what was causing it.

The real telling point was his observation that he has fixed this same problem several times during the week and the problem keeps coming back at the same clients he had fixed earlier.

So we both sorta concluded that it had to be something in the ATT cloud ... that they're doing something on the servers / network and not telling anyone else in support. So you have field techs trying to fix problems that they cannot fix since it is not in the "field" wiring/hardware.

If that is indeed the case, then I think that it would be in ATT's best interest to send an email to those affected (i.e., those of use who have DSL through ATT) to let us know that there might be connection issues without causing us clients to go through this.

Anyway, bottom line is that it is still having these problems and I'm still paying for Elite and not getting it.

I found that if I disconnect the modem through the modem setting page on my Speedstream 4100b, I can regain my speed. I don't know how long this last or what causes it to switch back to sub .50Mbs speed.

I've had DSL service here since 2004 without incident except for one modem blowing up.

I have powered off the modem, I have disconnected the modem via the menu, I have unplugged the LinkSys router, I have disconnected the internet cable, I have rebooted my PCs ... in various and multiple combinations. Nothing brings the speed back.

I found out today that my problem is not an isolated problem but rather a rather significant problem in the ATT "cloud" that affects many clients ... probably most are not anal enough to check their speeds on a daily basis so they don't yet know that they have a problem. Although based on the field tech who came to my house earlier in the month, a number of people have already noticed and reported the problem.

I wonder if that is my problem. I pay for Elite and it keeps dropping to 2.5 mpbs.

reply to rfluegge
What are your line statistics? I can't direct you to the modem page, other than for the SpeedStream 5100b, 4100, 4100b:

»192.168.0.1/statistics.htm

There are also some other numbers on the Technician Readout page:

»192.168.0.1/techreadout.htm

Any other modem, and you will have to wait for somebody who knows how to gain access.

Knowing those numbers will go a long way to deciding a course of action.

There was a card that was corrupt in The Colony central office.

They replaced it Thursday night.

It had to be replaced during the maintenance window being that there were so many customers working on that card. Replacing the card in The Colony corrected everything.

I started testing it on Friday night and it has been rock solid at 5.1Mbps ever since.

Many thanks to the AT&T Customer Service Technician, Network Services, who worked on my behalf, and to the others in Network Services who worked to make the resolution possible.

As another user in The Colony, I have seen severe fluctuations in speed. Currently (as of 1903CST 2009-06-29) my downstream speed is a whopping 36.46kbps. Upstream? Its 658kbps, which is right around what it should be.

As of 6:00 PM tonight (Monday) to 10:00 PM, it is back to the same problem it had before.

I hope that AT&T can finally get this resolved.

It was rock solid all weekend up through Sunday night at around 10:00 PM or so (that's the reason for the "thank you" posting) ... then tonight it went back to being crap ... same speeds you were seeing.

Right now it is around 15kbps ... really, really sucks.

This morning (0700) I was back at a steady 4.95MBps but it has since dropped to a rather unsteady 1.72Mbps. The odd thing is that through all the downstream problems, my upstream has been pretty much rock solid at ~650Kbps.

Mine has the same behavior ... download speed is very "unstable" while the upload stays consistent and nearly as expected.

Have you called AT&T DSL support and have they created a "ticket"?

I am going to check again tonight and see what the status is ...

I am actually in an online chat system with their support right now. We will see how it goes.

Can you run a traceroute to google.com? It looks like the problem is in the Richardson, TX VLAN routers, at least for me.

I've been escalated to the line support department. The automated line check they run can back clean and I'm on hold waiting for a support tech...

Probably the fastest I have ever been through the AT&T support system. I have a tech scheduled to show up between 12-4PM on Thursday. Kinda confusing why they would send a line tech out when they say the modem reporting a steady, clean 6Mbps signal yet throughput sucks. Seems to me that it would point to a network problem further up stream.

They are also saying that no one else in this area is currently reporting problems. Go figure.

Ok, I have at&t elite dsl with the nifty 2wire gateway. I am about to start pulling out my hair over this. Fluctuations in speed / latency and getting disconnected (in WoW). I have gone through, blown away dns cache, tried the open dns servers, went through a soft reset of the gateway plus a hard reset and still no joy. I suspect here in a few minutes when I try to jump on WoW I am going to be at 1000+ ms ping time to the server.

I have gone through the WoW forumn boards to track latency to the server and it is grotesque at a minimum.

I would love to get UVerse here in The Colony (grumble)

As soon as I can find an online chat link or something I would like to have word with at&t

I am going to call support one more time and demand a ticket to get this resolved.

They were already in on June 12th and tested everything including the wiring to the PC ... the problem was in The Colony Central Office.

They had isolated the problem to two causes: one was the "card" discussed above and if it didn't work they were going to pursue the second cause .... but they had been able to isolate them as hardware problems ... not on my line per se.

We all need to turn in "tickets" ... they're only going to fix it if there are a number of customers impacted ... the more tickets the greater pressure to resolve the problem.

Do you also happen to post on the inthecolony forum?

The Colony has a forum? Did not know that...

I just got through with the ATT support "Chat" ... They turned in a new trouble ticket ... supposed to be contacted do line test ... again!!!
