Speed ramp-up not working

My former speed was 768 K and was supposed to go up to 1.5 M today, however various speed tests show there's no change in my download speed.

The Connection Information on my modem says:
DSL UP
Connection UP
User ID xxx@sbcglobal.net
Connected at 1536 Kbps (downstream) 384 Kbps (upstream)
Modem Name SpeedStream Model 4100


That modem info looks OK. So why isn't it working faster? Do I have to do something?

You may need to restart the modem if you haven't already done that.

Just did that, a power recycle of computer, modem, and router. No difference.

Just spent a lot of time in a chat session and they said it's a problem with "customer provisioning", and it will be fixed by "Advance Technical Support" within 4 hours. Anybody wanna bet?

It's working now. I see that I've got a completely new range of IPs. This one starts with 99. Previous IPs all started with 75 or 76. So they had failed to change something in their system which assigns me to the tier of IPs based on my location and speed. Why didn't they do it automatically? Why put me through all of this time & trouble for something that should be routine? Nothing about AT&T works right. Their website is a nightmare.

I'd guess that they changed your gateway router (redback or BRAS) and that accounts for the IP range change.

Upgrade provisioning or even initial provisioning requires two settings to be completed. The DSL sync speed must be set at the DSLAM and the profile must be set within the gateway. This has always been so and getting both completed (mainly the profile changed) has been a problem for a long time.

I'm still not getting proper speed overall. Occasionally I get 1.2-1.3 Mbps down (like it should be) but more often it's like 0.2 Mbps or less. I can see from the speedtests that it's encountering delays along the way, like maybe traffic congestion(?). It hits a barrier and stalls completely for awhile, a second or a few seconds, then proceeds OK til it hits another barrier, etc. Sometimes it stalls a half-dozen times or more during a speed test. This is with 2 different browsers (Firefox and Chrome) and 4 different speedtests, as well as getting several different assigned IPs.

That's really a lousy download speed overall, on average. Is that something that can be fixed? Or it is endemic to the internet or the networks associated with AT&T handoffs/routing, or whatever. What's to blame here?

For numerous reasons speed test results can be bogus. What you really want to do is measure throughput speeds from more targeted sites, e.g. ones that you are typically downloading (or uploading to) from. This FAQ explains how to do this testing for FTP transfers, but the same method can be applied to HTTP transfers: »SBC DSL FAQ »How to measure throughput speeds on individual packets? You match the appearance of your results to the examples given to see possible throughput problem causes.

Unfortunately I don't think this method works for UDP packets (streaming sites).

It's still not working right. I had to call them again and it's a nightmare. They didn't even know what had been done before, and asked me the same stupid questions. Now they say it could take 4 days to fix. Absurd. I strongly doubt that it will ever be fixed.

As for the speed tests, I used 2 different browsers and 4 different speed tests:

0.27 Mbps 0.32 Mbps Firefox
0.55 Mpps 0.32 Mbps
0.21 Mbps 0.32 Mbps
0.71 Mbps 0.30 Mbps

0.19 Mbps 0.31 Mbps Chrome
0.62 Mbps 0.32 Mbps
0.25 Mbps 0.32 Mbps
0.34 Mbps 0.23 Mbps

0.39 average

just a question what kind of connection are you using in the wall can you move the modem from room to room? If so it could be your wiring in the house and you might need a direct wire from the modem to your network interface outside

Why is AT&T DSL so erratic and unreliable for speed?

This speedtest was recommended by AT&T tech. It shows 23 test results above the rampup point. 14 are OK, 9 are subpar. Other speedtests and browsers were also erratic.

»speedtest.net/results.php using Firefox 18.0.1 on Windows XP SP3

That's not the cause! I use a direct wire from the modem to the network interface outside. Ran it myself using high guage copper about 10 years ago. In the interim I've had the 6 Mbps DSL service and it worked fine, but couldn't afford it so scaled back to Basic.

Stop looking for faults in my system! The fault is in the AT&T system and internet routing...

Why is AT&T DSL speed subpar (unreliable) 25% of the time?

»www.speedtest.net/results.php?sh···30&ria=0
41 results after rampup
30 are Ok
11 are subpar
Why?

We're definitely not getting what we pay a high price for!

Maybe the test server is loaded. Try »speedtest.comcast.net/

I don't know what you mean by "loaded". That's the speedtest recommended by the AT&T CSR tech (speedtest.net). I've used 3 other speedtests (speakeasy.net frontier.com megapath.com) and they generally agree. The results are frequently subpar, as was the test with your comcast server:
»stage.results.speedtest.comcast.···8092.png

P.S. I ran it a half-dozen more times using different locations and only twice was it more than 1Mbps download speed. Most results were subpar...

OK. So don't try ping tests to your ATT gateway listed in your modem web pages (not your home gateway) or use the standard version of PingPlotter (30-day free trial) to that gateway and beyond-- because that could show local or non-local problems. Don't post your signal strength from the modem web pages.

I meant "loaded" as in fully loaded or overloaded... Having seen your test I tried it and got a very low set of numbers. Then I switched sites and got my normal speeds.
