ATT DSL Loses sync regularly, Tech Finds No fault

Hello,

I have been having connection problems with my DSL for months.

Originally I had a westell modem from when ATT was Bellsouth in my area. I called describing my connection problem and they sent me a new modem hoping that would be a solution.

It was not. They sent me the motorolla 2210, but I still lose sync. The DSL light blinks red and the resyncs shortly after. I called back and got a tech to come and attempt to help. He checked the line and told me that I have a very strong connection, and my internet (of course) worked fine the hour he was at my house. The modem acted somewhat funny at one point, so he left me another new Motorolla in case the one I had was faulty.

Well I still have the same problem.

There does not seem to be a pattern or a time of day it loses sync. It can happen anytime. It will go for hours some days with no problems, other days it will be disconnect and reconnect in rapid succession.

I have changed filters around, moved my phone to a different phone jack instead of the same as the dsl. Not sure what else to do.

Any suggestions would be greatly appreciated.

Thank you.

You could start with the line statistics. With the Motorola 2210, you can get them from »192.168.1.254/statistics.htm (I think). Of particular interest will be SNR and Line Attenuation.

It won't, got my new 2-wire last week.

Same old story...no rhyme or reason, they do a line check and everything is perfect. 15 minutes later, loss of sync. It goes on all day and all night.

I thought the extreme temps might be a cause, but last night it got down to 66 degrees(Thank God)and it still continues.

Side note-it took 10 minutes to post this. Cause? Loss of sync... twice!!!

I have a similar issue and I live in the Marietta area. In my case, I don't lose DSL sync but my PPPOe authentication drops all the time. So effectivily I am down. I had a Tech come out today and of course my signal is fine. He told me he thought there was a problem with the server that handles authentication in my area (RADIUS server) and that it was overwhelmed. He said next week he would try to get me moved to a different server. We will see...

i had this same issue, took 3 techs out and countless calls i finally connected my modem to the nid and reran stats and my stats were better. come to find out a tech couldnt find that my inside line was totally screwed. reran new wire from the terminal block to a new jack with new wire and it solved my issue.

Yep, a tech is not gonna mess with anything inside the house past the NID...that's what a NID is is a demarcation box, meaning everything up to that box they take care of, and everything past that box they don't take any responsibility for.

I believe for a fee you can get them to do inside checks, but it's alot cheaper to do it yourslef or have a electrician or somebody who has done it before help you with it if you don't do it yourself.

I've been doing ALOT of reading up on this stuff the past few weeks, and have learned a great deal about it. It's kinda finiocky to noise, and echo, and other things, but once everything is right, it's very stable, speeds never fluctuate, and it's very reliable.

I have an issue with Uncancelled Echo, but even with that ther connection is rock steady. I have been investigating that, and should have a fix in the next week or two for it.

It may suck if you are not aware of the rules, but unless you are paying AT&T for inside wiring support, AT&T's responsibility ends at the NID, and that is where their techs do their testing.

One of the changes subsequent to the 1984 divestiture of the RBOCs (Regional Bell Operating Companies) from AT&T was that premises wiring maintenance became an option. If the customer requested for the Bell company to maintain the premises wiring, the customer would be charged a monthly fee on the bill. If you are not paying for wire maintenance, the tech will not troubleshoot premises wiring without a minimum charge.

In the old Pacific Telesis region (bought by SBC around 1996), the monthly maintenance charge was called, "WirePro". Don't know about legacy Bellsouth.

I spent 6 months fighting this problem.
The first issue was that under Bell South I had a fixed IP address. AT&T did away with these free dedicated IPs without notifying their customers. Since the IP is assigned in the modem and does not change, then as long as you don't lose the lease on that address, the modem will work. However AT&T software causes the modem to log off and on about every 10 minuets under this condition. The fix is to turn off static Ip address by entering 0.0.0.0 in the address field.

The next issue is the system log on password. AT&T out sourced email to Yahoo several months ago. Under BellSouth a numeric only password was valid. A lot of people used their telephone number. Yahoo requires an alpha-numeric password. With a numeric only password the system will constantly log you out and at the next request log you back in causing very slow response. Of course AT&T never informed their customers and most of their tech support did not know this. I probably spent 20 hours on the phone with support before I got a supervisor that checked the yahoo profile and informed me what was going on. This changed in the past couple of weeks. AT&T has now separated the email password from the system login password. The above still holds true for the email password but the system password is now a system generated password of about 10 or 12 characters. The only way I know to get the new password is to call support.

I have also seen this problem being caused by bad hardware both the modem and the mux card in the dslam. The modem is not much of a problem since support will send out a new one without a second thought. They may try and charge you for the modem if yours is out of warranty ($85). Tell them “NO”, either send the modem or you will find another ISP. They’ll send the modem. The dslam card is another story. You will have to insist that it be changed. Have the tech report back to you after the card has been changed. I’ve found that most of the techs are good upfront types so treat them nice and they will do the same for you.

Hope this will help some of you.

Coming from an att tech allow me to clarify the above statements. First issues with static ip address (SIP) are either a BBG issue which would be a widespread outage to the tune of 10,000+ people or it is because of a multiple login, especially if you have a single static ip. This happens when the end user has their PPPOE login in use in more than one modem.What happens is you get a see-saw effect as one modem logs in the other logs out. If you have a SIP and a multiple login ensure each modem has their own unique password and user name in it; the agent you speak with should be able to determine this. Another thing to try is set the modem to always on if it is not a gateway so it ceases to throttle on and off during usage.

Second setting all ips to zero does nothing WAN side, all UID/Pass combos are what issue your SIP radius wise. As long as you have your uid in your modem and it has a SIP you are gonna get it unless BICS pulls it off.

Also the yahoo migration you speak of is a crap-shoot, the agent knows it, I know it. I have yet to see one single instance where that has come into play off the huge number of repair tickets I see.

Now as for the network password ie the randomly generated one, that IS legit. There have been a number of radius related surf issues caused by that debacle. Anytime I get a cu who calls in I always go through the motions of decoupling the password. Typically what you will see when it is the problem is DNS resolve related issues when surfing.

Finally issues at the element like you speak of with the MUX card at that DSLAM/ONU are rather specific in nature. Typically depending on the card (most common is Catena) what you will see is good sync on the port but no surf whatsoever. Attempts to authenticate will yield "cannot connect to target service".Intermittent issues are typically result from a loose dropwire and not so much at the element unless your port is throwing off a bunch of near end errors which DSG can check in their PM data list.

Interesting. I've never seen the condition where the modem logs off every ten minutes; probably because I never set my modem for "Connect on demand", or "Smart keep alive". I use, "Always attempt to connect".
The next issue is the system log on password. AT&T out sourced email to Yahoo several months ago. Under BellSouth a numeric only password was valid. A lot of people used their telephone number. Yahoo requires an alpha-numeric password. With a numeric only password the system will constantly log you out and at the next request log you back in causing very slow response.
That was just a holdover from the SBC days. We never used an all numeric password for the PPPoE login, nor were we able, nearly as I can recall, to use our phone numbers. Even before SBC contracted with Yahoo! to provide our email services, our PPPoE login was the same as our email login. The recent change you mention is likely driven by complaints from the legacy Bellsouth users, such as yourself.

I'm using the Motorola 2210-002. The modem help screen is as follows.

Static IP Address: Your service provider may tell you that the WAN IP Address for your Router is static. In this case, enter the IP Address from your Service Provider in the appropriate field. If not using PPP, a value of 0.0.0.0 enables address assignment via DHCP.
IP Gateway: The IP Address of the default gateway, or peer address if using PPP. This is normally set to 0.0.0.0 for PPP connections.

The way that I read it and the way it works from an empirical point is if the address is not set to zero then dhcp for the Wan is disabled. Once the lease is lost at the system side then there is not a valid address. No Address no comm. Pryor to this the system may have assigned this address to some one else but still maintained a lease with my modem. As you stated this would cause a see-saw effect. In my case I had been in contact with support off and on for a month and could not resolve the problem of slow latency time with the internet. I had a power failure which lasted for several hours. After power was restored, the modem would not connect to the WAN. I had a spare modem which I swapped into the system. It was set to dhcp, so the system worked until I tried to set up my dedicated IP. The system crashed. This and another long conversation with support was how I learned that I no longer had a dedicated IP. I swapped the original modem back into the system, set the address to zeros and it worked fine. This cleared up my original problem of long latency time.

As far as the yahoo password, it has created many problems. You may not see it in the support record because it rarely gets fixed. The customers either learns to live with the long latency times, don’t know any better, or do like you have and go to cable. This problem may now be resolved with the separation of the email and system login passwords but for people that are having latency problems its still worth checking. Check the yahoo profile and enter the new system password in the modem. Do you know of a method of getting the new system password short of calling support? Will AT&T be proactive for a change and mail the new password and instructions as part of the monthly bill or generate an email to all users with the password and instructions on changing it?

When you post a model number for the motorola 2210 you should use the full model number and since there are three versions of software that number should be posted too

bellsouth requires the use of pppoe for all accounts

There are websites where the subcriber can change the network password and the account password

What it says in the Motorola 2210 about entering you static IP address is wrong when using FastAccess DSL service. You should never hard code the static IP address that AT&T Southeast has assigned to you.

These static IP addresses are not really static IP addresses. It works the exact same way as the dynamic IP address except it is supposed to assign you the same IP address each time.

Your static IP address is assigned based on your PPP login credentials and it is done with Internet Protocol Control Protocol (IPCP) instead of Dynamic Host Configuration Protocol (DHCP).

I had the same password for the longest time after I migrated to SBC Yahoo! DSL Service as I had before migration. Although I have changed it since, I have not had any problems relating to the password. Certainly not WRT to latency.

In the Bellsouth world (legacy bellsouth), the network and email passwords were always separate. By default, they were both set to your phone number (really f'ing stupid!) but were independently settable.

I've been a Bellsouth.Net user since before DSL existed; my email and network passwords have always been different. (not that I use them for email.)

I don't know how latency is involved in properly using your username/password, unless you are talking about the latency that it may take some to figure out how to do it.

As for customer notification, AT&T sent out an email a couple of months ago detailing the new password change/reset procedure:
said by AT&T :

Important Change to Password Reset Process

Dear AT&T High Speed Internet member:

As part of ongoing service enhancements to provide you
with a better Internet experience, we have changed the
process for resetting your account password, making it
simpler and more convenient.

This email is for information purposes only. No action
is required at this time.

What's Changing?

You have two passwords that you use with your AT&T
High Speed Internet service:

1) Your primary account password used to access your
email, att.net home page, and account management features.

2) Your DSL network password used by your modem/gateway
to connect to the DSL network.

Previously, both passwords were required to match. If you
changed your primary account password you also had to change
the network password on your modem/gateway, or else your
Internet service would be disrupted until the network
password was changed on the modem/gateway.

To make it easier for you to update your account password
and avoid confusion or connectivity issues, we have improved
the process so that you no longer need to reset your DSL
network password when you change your primary account
password. You will be able to change your account or email
password at any time, and as often as you like, without
changing your network password by visiting our Online Help
site at »www.att.net/AccountPasswordReset

What do I need to do?

Although no action is necessary at this time, it is important
for you to take note of this change.

If you wish to change your DSL network password at any time
in the future, you can get more information by visiting our
Online Help site at »www.att.net/NetworkPasswordReset.

We hope that this change will offer you more convenience and
that you continue to enjoy your AT&T High Speed Internet
service.

Thank you for using AT&T!

Sincerely,

Your AT&T High Speed Internet Customer Care Team

If my local small business clients are typical, then it is a common occurrence. Many of them regularly ignore such advance warnings from their ISPs, their email/web hosting providers, and their domain registrars, and then expect me to make it work again. I sometimes wonder how some of them stay in business if they pay as little attention to other aspects of their business as they do to internet access and their web sites.

Thanks for posting the notes from AT&T. I don't believe that I ever received them. But let’s assume that I did. The emphasis in the notes is that this is for informational purposes only. Where are the notes that say "Do this or you’re going down"?

I think that I need to define the term of Latency Time. This is the amount of time it takes from clicking on a link until the page is returned. This of course includes DNS lookup, site delay, comm. time, etc. My problem was that it would take 10 to 15 seconds to open the link of yahoo.com. Once the login was fixed, yahoo.com opens instantly. I'm using yahoo.com as an example, all links were very slow. My understanding is that with the numeric only password, AT&T/Yahoo would log me off the DSL system. When I would click on a link then I would have to logon to the system first. The login servers are slow which is ok since the login should only be done once at boot up time. You can see that having to login at every request will slow the response time down to the point that dial-up would be faster.

I could answer that, but you would not like the answer.

That makes absolutely no sense at all. If the password were invalid, you would not get a PPPoE authenticated session in the first place (AKA, sync, but no surf). My money is that you at some point in time had your modem/router Connection Type configured to [OnDemand], and while you were changing/resetting the password the Connection Type got changed to [Always On].




The primary reason that the [OnDemand] and [Manual] settings are there is because some ISPs have in the past charged by the kilobyte or by the minute (and some may still do it). For a normal always on DSL connection, you should always use a Connection Type of [Always On].

Just to update my status (I was the OP).

I have had several techs come out since. I have IWP so they ran a direct like from the NID to my modem. They also changed the splitter at the NID, as well as giving me a new phone jack with the new line from the NID.

In other words, every possible problem inside has been taken care of. I still have the same problem. I still lose my connection, usually at the worst time possible.

I just got off the phone with ATT and they said that everything looked fine on their end and to call back when I get disconnected again....

But I know what will happen, I will get disconnected, I will call back and they will run tests telling me everything is fine since I am connected again -_-

I've been having this issue, too for the past three or so weeks. They blamed my modem so I let them send me a new one. Replaced it and the cabling that it came with and I still have disconnects constantly. When I call support, the script readers keep asking me about my computer like idiots.

I was just gonna wait it out since Uverse is supposed to go live in my neighborhood in the next month or so but I'm not sure if I want stay with ATT.

I have had the same issue with AT&T Dsl, dropping connection on average 20-30 times/day. I've had the dsl for two years but the problem only for one. This is a brand new neighborhood with only about 10 houses right now and I'm the only one using DSL, everybody else is using cable. The station, which connects copper to fiber in this case is about 1000 ft away. So here's all the information.

Here's the solution:
After about 6 or 7 technician I got a good tech. I mean they've changed everything by now, and I knew the issue wasn't house wiring, professionals did that and nothing changed from when there was no issue to when there was one.
1. They changed the cable from the house to the DSL box (no change).
2. They changed the modem like 3 times (no change)
3. They changed the filter several times(not sure since the last time it had noise and the latest one was changed at the same time as other stuff).
4. They changed the cable from the DSL box to the Fiber terminal twice. The second time was with the last time like the filter, but the tech did a direct line rather than going through all the other DSL boxes on the way there as standard.
5. They changed the "Card" at the Fiber terminal (no change)
6. They changed all the equipment that was there in the DSL box outside the house and the one attached to the house (possible change with the one attached to the house since it was changed the last time with other stuff).
7. Last but not least they changed something the tech called the "port" at the Fiber terminal. Since this is the only thing that none of the other techs changed (I think) this has had to be the problem. Since the tech left 0 sync losses in two days now!

So in my case the issue was the the station that connected to the fiber cable. (And even out of that stuff it seems as if the problem was just those ports)

Hope this info helps you and the AT&T techs.

obaryshnikov Your post was helpful but the next customer the tech that may have fixed your problem by changing the port may find their problem is one of the other 6 problems you listed before the port change. The same problem you had may not always be the port. All the 6 parts you listed have to work together perfectly. The biggest problem is the tech is not given enough time to eliminate each of the 7 things on your list. Changing anything caused the link to reset and run clear for a short period of time. The tech thinks it is fixed but you the customer see the trouble come back in an hour, a day or the next week. The next tech may not have any idea what was changed on the other visits. The other problem with DSL repairs is like looking for your keys they are always found in the last place you look and sometimes you wonder why you did not look there first. I will say they did a lot of work that better testing did not need to be replaced or changed.
The port is the electronic assignment to a card at the dslam where the fiber connects. Think of the port as like your home mail address and the card as your mailbox.

Your post may be helpful to other customers just from reading all the stuff that was changed and therefore be more knowledgeable when they talk to a tech.
Thanks
