Re: Has AT&T lowered the DS throughput speed for Xtreme 6.0?
I would be more inclined to suspect changes in the way the loops are provisioned. Bellsouth and SBC provisioned their loops in different ways. AT&T is likely trying to do it all the old SBC way (considering that it was SBC which bought AT&T) in all regions.

You know its weird, on speedtest I usually get 5.5 up to 5.78 after tweaking, but at one location 'Cincinatti' I get 5.94 to 5.98....I havent figured out why that is yet...

I did some heavy downloading this weekend after an operating system upgrade and it seemed to max out at 5.8 Mbps. Not a huge deal from the 6.5 it used to be. But still, after all this time service has degraded on many levels and not improved.
I've been a DSL customer for about 9 years now and Comcast is starting to look like it might be worth a switch. Faster speeds now and an upcoming upgrade schedule that is a little more tangible. |

1 edit | Thanks for the info....
But I'm too competitive and inquisitive to sit by and and accept defeat after the speed change occured....I'll probably stop tweaking when I get a speed test to show '6.0' or better...I can't give up just because Bellsouth throttled me 
btw It appears that the westell 6100 modem kncoks 8 off of whatever mtu is set in the computer nic settings...I guess it figures the computers will be set at 1500....the tcp analyser always shows 8 less than whatever I set....i.e. I set 1492, it'll show 1484.....(That was puzzling for awhile)
I have the recieve window at 255552 I believe.....I hate I have to work 2nd shift today or I'd re-experiment with the mtu and rwin settings again....Guess it'll be later tonight..

Tweaks do not affect the sync speed of your modem. You can tweak all day and all night but until whatever is causing your modem to sync lower than it should is fixed, it won't make a difference. |

I have also been seeing inconsistent download speeds over the last month or 2.
I have the 6Meg and use to always get this ... and I tested often.
- I have been with Bellsouth/ATT for about 8 or 9 years now.
I suspect ATT's network is suffering from U-Verse and the iPhones. When the new iPhone 3GS came out in June, ATT said the new feature to send MMM (Multi Media Messages) will not be possible until the end of August when they expect to fix the network issues (not enough capacity).
- ATT is the ONLY ISP (globally) not allowing MMM on iPhone .
- They have oversold their stuff to the point it is breaking our good old Bellsouth da'ys performance!
Lately, my testing every day shows a pattern ... I am lucky if I get over 2.5Meg download during "peak times".
And I am surprised if I don't get the old 6Meg download during "non-peak times".
I have tested with MANY variations ... 4 test sites, 4 different computers (not counting iPhone) and 4 different operating systems, unplug everything and replug, and more ... no luck!
Charter is offering 20Meg download NOW in my area and I am getting it installed asap.
I will keep the DSL for a month or 2 ... just in case I have to cancel the Charter setup for poorer performance ... but seems unlikely... I hope not likely.
I have been patiently waiting for higher DSL download speeds with zero luck. U-Verse is suppose to be coming but I have several issues with this "totally new" service.
And I really don't like the trend of ATT becoming a monopoly again .. buying Bellsouth buying Cingular ... and packages that make NO sense like the ONE (1) package for Internet on the iPhone at $30/Month !!!
Are these guys trying to get rid of loyal customers ? |

Roger that, I understand, and will look into it again....
However, i will still keep tweaking, because its fun! Anyway I upped the rwin to 511104 and got this result just now from Cincinnati

Well its only fair to post ATT did something on their end to allow more bandwidth to reach my location. I called when my download speeds dropped to the low 4's. I believe they sent a tech to check the dslam and the lines. They were going to check my home lines but whatever they did on their end resolved the issue. |

| Rammer, AT&T's internal testing compared to the speed I was getting showed I was using all the bandwidth being provided to my location. I didn't need to convince them. I just called with the issue that my speed had continued to degrade over the last year. The Customer Service Rep was friendly and helpful. |

the dslam card was reset and moved your connection in the router to a different port, all going with the hope that it will help since there are not any signs in the portion we control about congestion or packet loss,
have a new nid box also with -- new splitter--
i also ran a new cat 5 cable --new wall jack ---new phone cord
but still no luck on speed drops-
saturday -8-29-09--12.45 pm
and this all i can get
i keep sending these too att

I have had a tremendous speed drop also.
About 2-3 Weeks ago I started getting speed drops.
This made Youtube/streaming video load extremly slow.
I checked and at 3 weeks ago U-verse became avalible to my general area.
Now I do not have Xtreme 6.0 but I used to average out at about 4 Mbps and about a 35(ish)kbps
Now my speeds have dropped to this.
I think it has something to do with U-Verse because of the other members having problems. I'm going to call AT&T out and see if they can look at it.
(I really hate AT&T/Bellsouth. I would switch to Charter Cable Internet if I wasn't just 8 inches past the limit line. :/ |

I finally took the time to call ATT tech support for my current problem of inconsistent speeds.
They did something to my "profile" and my speeds are consistent again at pretty close to the 6Meg download I pay for.
I must admit ATT DSL tech support works pretty good.
The tech put in on an Email list for when U-verse becomes available for me, but still no "hint" at when this might be.
Fyi ...
I put this off because the last time (lots of disconnects and inconsistent speeds) it took more than 1 call for an hour or so per call and they had to send a tech support to my home.
- There was more than 1 issue causing my problems then.
- But I must admit, the tech support guy was extremely good in catching one of the issues causing some of the problems.
- I had recently moved and was using an old modem AC adapter which was causing the issue ... MY FAULT. |

said by silentfrost :I think it has something to do with U-Verse because of the other members having problems. In a roundabout sort of way. Uverse only requires conditioning of the F2, the copper from a cross-connect to the premises. They pull fiber to that cross-connect (actually, to a VRAD adjacent to the cross-connect; and patch the VRAD to the F2 in the cross-connect).
The consequence is that, for DSL connections with a respectable F1 (cross-connect back to the CO), but an F2 in bad shape, Uverse can actually even improve the DSL side.
But, for DSL connections with a bad F1, no amount of conditioning of the F2 will help, and DSL will appear to be "affected" by Uverse (because, for AT&T, Uverse is the future).

Next time (if there is one) I will NOT put off the 1 phone call to AT&T Tech support.
DSL is staying consistent which is nice ..
especially when I get speeds like the ABOVE !
