[Speed Problem] AT&T merriment or cruelty ?

Hi,

I started out many years age with DSL Download Speed: ~ 600 kbps.

When AT&T installed a remote terminal nearby for their "Universe" (SP) my Download Speed increased to: ~ 1300 kbps.

It has now decreased to:

Download Speed: 959 kbps (119.9 KB/sec transfer rate)
Upload Speed: 308 kbps (38.5 KB/sec transfer rate)
Latency: -1 ms
Thursday, October 10, 2013 11:54:52 AM

Can AT&T be pressured to increase the speed?

No, you arent on the U-verse vrad, only Uverse customers are, you are still on the same phone line to the CO as always, should open a ticket with earthlink for slow speeds

Then why the jump to 1300 about the time my mailbox was full of Universe and AT&T knocked on my door to announce Universe.
The CO is way too far for 1300 to work, ~ 600 was a solid limit when I first connected, the person who raised it was clear on that point.
~ 900 now says I am on the remote terminal still.

It is, "U-verse", not "Universe". Unless you were issued a new modem, it is very unlikely that you have U-verse.

As an Earthlink customer, you would have to go through Earthlink support. Can you post the line stats from the modem? If you don't know how, post the make and model of the modem.

Hi,

Earthlink DSL ZyXEL Modem
ZyNOS F/W Version: V3.40(AHC.0) | 11/16/2005

But it will not respond to the old IP address, I have upgraded my Wireless Router.

I vagely remember having to disconnect the router before in ~ 2005 when I looked at the stats, or I had no router then.

Hardware Version WNDR3700
Firmware Version V1.0.7.98NA

Internet Port
MAC Address xx:xx:xx:xx:xx:xx
IP Address xx.xxx.xxx.xxx
Connection PPPoE

It will not respond to the new IP address either.

Perhaps due to PPPoE.

I have never looked at the stats after the increase to 1300.

If the ZyXel is bridged, you will need to connect a computer directly, and set the computer IP address manually. E.g.: If the modem IP address is 192.168.0.1, configure the computer to be 192.168.0.10. This is more likely due to the ATM than the PPPoE. The router encapsulates the IP packets into ATM cells, and then passes them to the upstream ATM device. Once encapsulated, the IP destination is not available to the router, so won't be routed to the local gateway.

As for U-verse, I am reasonably certain the ZyXel is not IPDSL aware, so it couldn't work on a U-verse IPDSL circuit.

Hi,

I remember setting the bridge when the first wireless router was installed. That would need to be reversed to do the test.

It has been so many years, but I remember that when the frequencies was tested, only those that the CO had enabled could be tested. The person who raised the initial speed from the default ~ 300 to ~ 600 was told by the person at the CO that the line at that time could go no higher.

So I was surprised and pleased when I suddenly got ~ 1300 right after AT&T knocked on my door announcing U-verse.

No change on my end was made, the improvement had to be the remote terminal installation close by. (I know where it is.)

The copper in the ground is the same as installed forty (40) years ago to the RT location.

If a U-verse IPDSL circuit is a new way to push higher speeds through the final copper, then it is beyond my understanding as I have not researched that subject.

I am just trying to understand why the drop from ~ 1300 to ~ 900 has happened. I can tell the difference without checking the speed (EarthLink, CNET and SpeedTest).

Is AT&T playing games with me to try and get me to switch away from EarthLink. (YES, they send me four letters of mail
sometimes in one week, 3-4 times the speed at 1/2 the cost.)

I would be happy with the ~ 1300, I am not with ~ 900.

IPDSL will not necessarily result in increased sync; that is determined by loop length, condition, and AT&T policy. Worst case would be no increase in sync, and modest increase in throughput.

I am just trying to understand why the drop from ~ 1300 to ~ 900 has happened. I can tell the difference without checking the speed (EarthLink, CNET and SpeedTest).

Understanding why will require seeing what the modem is reporting for "Noise Margin" (aka, "SNR"), attenuation, and sync rate.

Is AT&T playing games with me to try and get me to switch away from EarthLink.

I doubt it. They certainly aren't "gaming" my CLEC connections. Do you know if you are on an AT&T DSLAM, or an Earthlink DSLAM?

Hi,

"AT&T DSLAM", I am not familiar with that term, my AT&T phone bill says "Shared Line Service".

I doubt that Earthlink was involved with the Remote terminal installation. Earthlink is paying AT&T some money from what I pay AFAIK, they may have supplied a card for my line when it was all the way to the CO. Now with the RT I just do not know, but consider it unlikely.

AT&T ran a fiber to the box just before my home and converted all lines to a Remote Terminal so that the copper to the CO is no longer in use. (Thanks AT&T, part of U-verse upgrade.)

Just trying to understand your situation. In April, 2011, I moved my mother from AT&T to a CLEC service provided by a carrier which maintains their own DSLAM and switchgear in an AT&T CO. They pay a modest monthly line rental for access to the copper loop to the premises; so that residence is still on a CO connection.

Hi,

I think that the key is that I have phone service (landline) on the SAME copper wires as the DSL service.

The phones both have a low pass filter and the DSL has a high pass filter. I have several spares, I was going to put the filters right where the phone line enters my unit, one pair for DSL, one pair for phone. Never did it, it may have helped.

Manual for DSL box is missing, 50+ boxes moved around two weeks ago for termite fumigation so I do not know where to look. Need it or find it on line first.

As the CO is so far away, I never could have seen ~ 1300 at any time unless the RT was in use.

I am not sure Remote Terminal is the correct term, but fiber to the RT in the close by box was either in the TV news, newspaper or in the endless letters AT&T sent me. It is a computer for sure and too small a box for cards like in a CO. This says I am using the correct term.

Well I went back to 1.3 Mbps a few months ago. I think the cable which has been in the ground now 40+ years ago is affected by water in the ground. CA is in a severe drought currently.




Later today I will try and look at the ZyXEL P-600 Series stats.

WHY?

Earthlink is going to tell AT&T to raise the max. rate to 3.0 Mbps at no change in cost, well except for the recent price change. (DSL 1.5 Was $29.95, now $34.95.) And still use the seven year old modem.

I really do not like these numbers. How can the same modem go to 3.0 Mbps?
Will 4-wire instead of 2-wire be used.
8/20/2014 the switch will be done.
I will report if I can.

Very old original firmware. Try updating the ZyXEL using the Earthlink upgrade file.

»EarthLink DSL FAQ »How to upgrade the Zyxel P-660R-ELNK modem firmware

The file will not run unless the modem is directly connected to the PC Ethernet port and is the correct firmware on the Modem so it cannot damage a incorrect unit.

Earthlink does not have or need pair bonding as standard ADSL is a single pair of wires that support up to 8 Mbps if you are close enough to the DSLAM.

Are you saying there is a filter on the cord that the DSL Modem uses to connect to the wall jack? If yes that is incorrect as the DSL Modem should be unfiltered.

1. I am not sure the firmware is for my Modem as it is Seven (7) years old.

2. AFAIK there is a low pass filter for normal voice and a high pass filter for DSL.

3. Remember the phone cable was put in the ground ~ 1970. ~ 0.4 Mile from Remote Terminal.

4. ~ A decade ago when I was using a 56k Modem the rate went down to ~ 300 Baud. The wire splice out near the main sidewalk had gone bad. The noise voice as so loud that you could not talk.

5. When the ground gets wet the download speed drops to 0.96 Mb/s. California is very dry now thus the higher speeds.

It is Earthlink Firmware for the Earthlink ZyXEL P660 Series Modem. If it, as you say, is not for your Modem then it will NOT, as I said previously, harm or update your Modem.

Earthlink DSL is to have the voice jacks filtered and the one jack for DSL Modem unfiltered. Anything else is wrong unless you have a dedicated run from the NID outside that is 100% unfiltered all the way to the jack that the DSL Modem connects to.

The Firmware was applied and it at least made the screens match the EarthLink articles. (I have ZyXEL P660R-ELNK)

The EarthLink tire 3 person is sending me a new Modem to arrive tomorrow.

The biggest problem is the 40+ years old buried cable 0.4 Miles from the remote terminal.

Do any modems us 4-wire from the Remote Terminal?

There must be a twisted pair from the RT to where it enters my unit available for a second phone. Can a switch at the RT and where the cable enters my house allow use of the second twisted pair instead?
--------------------------

The box that is behind the heavy bookshelf and is not reachable plugs into the phone jack (Which I installed my self ~ 30 years ago when it became allowable to own your own phone). It has two jacks, one for voice phone which has a low pass filter and a DSL jack that I remember has a high pass filter. I used it instead of the EarthLink supplied one that would have required the bookshelf be further from the wall.

Purchased Seven (7) years ago from MCM. What a great store. E-Mails almost every day. My last purchase was 3+ years ago.

Hi,

Well the replacement modem arrived and the results are almost the same as the original modem. Just a tad better. So I have gone from ~ 1.3 Mbps to ~ 1.61 Mbps.

I can post the line stats, but as they are so close, there perhaps is little reason to do so.

I still am interested in answers to the questions in my last post.

Yes, the Uverse Modems which are bonded VDSL or now VDSL2/xPON. Earthlink doesn't resell Uverse service though so Earthlink only requires a single pair of wires to operate Standard ADSL (Up to 8 Mbps).

Thanks, I will live with the 1.51 Mbps that the replacement modem (and the seven year old one gives). Just the slight increase from 1.3 Mbps has helped.

Should AT&T not get to my location with 1 Gb service (They are starting to the South in Cupertino, CA just like the Street Light Pole ISP which Santa Clara still has) I will stop answering my door, reading my mail and answering the phone after fighting like mad to get CommieBlast cable stand alone Internet installed. (They only want to sell their bundle even though the FCC got a huge amount of money from them.)

The entry point for both AT&T and Cable (Fiber) is on the wrong side of my unit and down stairs so both are problems in my ~ 42 year old townhouse.

I did some tests, plugging the modem into a jack that has no filter as you did not like my words about a high pass filter. No Change.

I also disconnected the two phones I have and tested again with no change. That suggests to me that a whole house split using one pair for phone and one pair for DSL would not help. As well as running a cat5 cable out a lower window to a modem and wireless router is not worth testing.

I will be checking to see if I have a network interface device (NID). The box cover has been painted twice so it may be hard to open. I do not think the older method is affecting my DSL service.

It's the ~ 42 Year old cable 0.4 Mile long in the ground.
