| Re: [DSL] Here's my 11 items, please advise. The Tweak and Line Quality tests are inconsistent. The Tweak test says you are pingable, but the Line Quality test says you're not. Did you change something between the two tests that would have affected this?
You have retransmission errors. That will affect your speeds. We need to get the errors cleared up, then we can proceed with tweaking. Try these:
»Tweaking FAQ »What does power-cycle my modem mean and how do I do it?

| Let's try one thing while you're doing those:
-Download Dr.TCP.
-Set the TCP Receive Window (RWIN) to 32120.
-Set everything with a pull down option/menu to Default.
-Blank/Clear all other fields.
-Save.
-Reboot.
-Post an up-to-date tweak test.
-Post the results of the speed test nearest you. | |

Hmmm, I'm getting anywhere from 98-530kb for downloads, it seems rather erratic and inconsistent. What's wrong with my connection?

| Re: [DSL] Here's my 11 items, please advise. To answer your first question, I don't know if "DSL Speed" affects it or not. We only use DrTCP here on this site. Some do appear to cause problems, but I don't know about this one. I'm still one of the "new kids on the block", so if one of the "old timers" comes along, maybe they'll have some information about it.
However, if you can disable it, it would help me analyze what's going on relative to your inconsistent speeds. (As an old IBM performance analyst, I believe in eliminating as many variables as possible when looking for something like this.)
I know you've run Line Quality tests before, but, run another one, making sure you are pingable. | |

| Re: [DSL] Here's my 11 items, please advise. OK, let me describe what I'm looking at.
1) Look at the EC (East Coast) plot and compare it with the WC (West Coast) plot. The WC plot is (mostly) flat on top. That's the way it ought to be. The EC plot, on the other hand, has a "saw tooth" pattern. Not good.
Now, where's the problem?
2) Look down the columns of numbers. I'm looking at best, avg, and worst. On each row, look at the difference between best and worst. If there is a small difference (like a millisecond), that's good. Look at the "(YOUR ADDRESS)" line of the EC data - the difference is 16 ms. Not good. Same line in the WC data has a difference of 62 ms. Those lines are the only ones that have differences above 1 ms.
Therefore, the problem is between rback2-fa2-0.fyvlar.swbell.net (your gateway into the SBC network) and your computer.
Now, the problem is: what's causing the problem? We start with:
»Tweaking FAQ »What does power-cycle my modem mean and how do I do it?
»/faq/5322
I posted those earlier, but I don't know if you did them.
Additional questions:
1) What type of wiring goes to the modem? Is it "plain old flat phone extension" wire? Or is it "twisted pair" cable - like cat3/5/5e/6 cable?
2) Can you move the modem close to the NID (the gray box on the back/side of the house) and see if the errors go away?
Let's stop there and let you catch your breath and get a few winks of shut-eye.  | |

| Re: [DSL] Here's my 11 items, please advise. The flat stuff can pick up noise (hum) from other electrical devices. This can cause errors. Did ADSL Guy have you unhook everything but the modem? If not, you might try that and do another Tweak and Line Quality test to see what happens.
To clear up problems I had, I finally replaced the wire that ran to the modem with cat3 and put a splitter at the NID. My service became very stable after I did that. I wish now that I had put in cat5. | |

Fayetteville, AR | Now I'm confused. I'm using a Cat5 wire connecting to the NIC to the modem. When you said "Splitter", is that the filter?

| Re: [DSL] Here's my 11 items, please advise. A "splitter" is a device that is better than a filter.
A filter is placed between POTS (Plain Old Telephone Service) devices and the line to keep the POTS devices from draining off the high frequency signals that DSL uses.
A splitter goes out next to the NID. The one I have (and they may all be this way) has active circuits in it (a transistor) that splits the signal into low frequency and high frequency portions and puts them out onto separate connectors that go to the POTS lines and the home-run (CAT5) to the modem. This circuitry also does a combining function to the signals going back toward the phone system.
The FAQ articles on this indicate that the splitter is the preferred device, especially if you already have a home-run.
Did this make sense? | |

| Re: [DSL] Here's my 11 items, please advise. There's a FAQ about where to get splitters ( »AT&T Southeast Forum FAQ »Splitter, DSL/POTS ? Where can I get one? ). I don't think you'll find them at RatShack.
Here's a link to the one I got: »www.allentelproducts.com/Catalog···PID=2010
Here's the invoice information I got:
1 - Allen Tel AT626DSL - DSL Splitter Outdoor Device @ $39.99ea. = $39.99
--------------------------------------------------
SubTotal = $39.99
Shipping & Handling (4 - 6 Days Delivery) = $5.00 (Residential Delivery)
State Sales Tax = $0.00
--------------------------------------------------
Total for Order = $44.99 | |

| Re: [DSL] Here's my 11 items, please advise. It was easy. (But, then, I've been messing with wiring and stuff like that since I was 8 years old. )
Do you have a friend that's a "handy man"? Actually, it doesn't take many skills. There aren't that many connections on the splitter I got. And, they are clearly labeled. The instructions were also pretty clear. | |
