Verizon DSL and XP Professional???

softworks · Post by **softworks** » Sun Feb 24, 2002 8:44 am

I have a computer with 2000 Professional, 98, 98, and XP Professional. The 2000, 98 and 98 get a download speed of 660kb\s out of a total 768kb\s, which is great. But my XP Professional machine only get 473kb\s at constant. I tried the QoS thing already and tried tweaking RWIN and etc with the TCPOptimizer. I am kind of lost and stuck, can you help me?

Oh yeah, forgot to tell you that I changed to the native XP pppoe because I was using Raspppoe but found XP was more consistent.

Try everything I posted here with the exception of try the following changes:

DefaultRecieveWindow/ GlobalMaxTcpWindowSize/TcpWindowSize= 31944,46464,63888,95832,127776

Try all of these and see if it helps.

It is now downloading at 495kb\s. Anymore suggestions?

IMO your Rwin (Recieve Window) should be 20048

softworks · Post by **softworks** » Mon Feb 25, 2002 6:18 pm

I changed it to that RWIN. Its the same. Anything else? Could it be windows XP?

Run Tcp analyzer and put in smallest number in as RWIN, apply changes and REBOOT first

Bob Carrick · Post by **Bob Carrick** » Mon Feb 25, 2002 6:33 pm

Using what tool? And did you reboot before testing.

Lobo · Post by **Lobo** » Mon Feb 25, 2002 6:35 pm

and tried tweaking RWIN and etc with the TCPOptimizer

softworks · Post by **softworks** » Mon Feb 25, 2002 6:44 pm

Ok I changed my RWIN to the lowest. Its the same. And yes I did reboot......???

Lobo · Post by **Lobo** » Mon Feb 25, 2002 6:45 pm

Bad mnosteele, non of these numbers are multiples of MTU 1480 but MTU 1492

softworks · Post by **softworks** » Mon Feb 25, 2002 6:47 pm

Anymore suggestions?

Bob Carrick · Post by **Bob Carrick** » Mon Feb 25, 2002 6:50 pm

I hate to suggest other tools but I know for a fact this tool does change the Recieve Window on XP http://www.dslreports.com/front/drtcp.html
Try the value I suggested.

softworks · Post by **softworks** » Mon Feb 25, 2002 6:53 pm

I have been using that to change my RWIN because TCPOptimizer only allows me to change it, while mot keeping the others settings at default. Any other suggestions?

Lobo · Post by **Lobo** » Mon Feb 25, 2002 6:54 pm

Are you selecting DSL PPPoE at top, selecting adapter, custom settings, apply changes and REBOOTING

Bob Carrick · Post by **Bob Carrick** » Mon Feb 25, 2002 6:55 pm

With Dr.TCP, please m,ake sure you select your Ethernet card in the drop down menu, and not the default PPP adapter.

softworks · Post by **softworks** » Mon Feb 25, 2002 6:58 pm

Yes I am. It doesn't seem to speed up anything. In fact I get 495 with the native XP PPPoE set at default settings, than with TCPOpt. in which I get 473. So right now I am using the defaults and an RWIN of 63360. ...???

Lobo · Post by **Lobo** » Mon Feb 25, 2002 7:00 pm

try that number in half

Bob Carrick · Post by **Bob Carrick** » Mon Feb 25, 2002 7:00 pm

I thought you said you couldn't change it? Or does it mean it didn't change your speed? No tweak is guarenteed to help your speed your problems could be line related, home wiring, ISP problems etc. etc.

Lobo · Post by **Lobo** » Mon Feb 25, 2002 7:04 pm

Dr TCP is not changing GlobalmaxWindowSize????

Lobo · Post by **Lobo** » Mon Feb 25, 2002 7:10 pm

I have a computer with 2000 Professional, 98, 98, and XP Professional. The 2000, 98 and 98 get a download speed of 660kb\s out of a total 768kb\s, which is great. But my XP Professional machine only get 473kb\s at constant

I don't think it is the phone lines

Bob Carrick · Post by **Bob Carrick** » Mon Feb 25, 2002 7:10 pm

It changes TCP Recieve Window, I do not know if they are the same thing. But yes it does work in XP.

softworks · Post by **softworks** » Mon Feb 25, 2002 7:12 pm

When I change the RWIN, I change the GLobalMax, TCPWindow, and DefaultTCPWindow.....??? Apparently the speed still stays in the 490 to 495 area.

softworks · Post by **softworks** » Mon Feb 25, 2002 7:34 pm

Help???

Lobo · Post by **Lobo** » Mon Feb 25, 2002 7:40 pm

Where are you from

softworks · Post by **softworks** » Mon Feb 25, 2002 7:44 pm

Upstate NJ. Does this help you to help me???

Lobo · Post by **Lobo** » Mon Feb 25, 2002 7:48 pm

Well if you don't use Optimizer with RWIN you have now im lost

Bob Carrick · Post by **Bob Carrick** » Mon Feb 25, 2002 7:51 pm

I can't help since my last question has still not been answered about Dr.TCP "I thought you said you couldn't change it? Or does it mean it didn't change your speed? No tweak is guarenteed to help your speed your problems could be line related, home wiring, ISP problems etc. etc."

softworks · Post by **softworks** » Mon Feb 25, 2002 7:59 pm

Like I said, my network is fine because I tried the Win2000 laptop with my CAT 5 cable that connects me to the internet. The results were faster on the laptop. So I assumed the problem was an my end. And DrTCP does change my RWIN. In other words my RWIN is changed and my speed is the same at arounf 490kb\s to 495.

Lobo · Post by **Lobo** » Mon Feb 25, 2002 8:06 pm

Use Optimizer with RWIN you have now, if you don't like, click on File, restore defaults

softworks · Post by **softworks** » Mon Feb 25, 2002 8:09 pm

Doesn't work, speeds remain the same.....

Lobo · Post by **Lobo** » Mon Feb 25, 2002 8:11 pm

Restore defaults and see what speed is, if it's the same, put the coffee on

softworks · Post by **softworks** » Mon Feb 25, 2002 8:12 pm

What do you mean mby "put the coffee on", lol?

Lobo · Post by **Lobo** » Mon Feb 25, 2002 8:12 pm

Do your speed tests here after you turn off all running programs http://www.speakeasy.net/main.php?page=sup_pops , select site nearest to you, turn everything off thats running, Check Tasbar, 1 browser, clear cache

Even though it is not the nearest the Dallas test is pretty quick

BEFORE SPEEDTEST
1.) Make sure defrag has been run, defragmented files slow you down.
2. At top of IE, click on Tools, internet options, click on delete files and click on offline files (It's safe), click on clear history, yes
3.) Go to Start button, programs, accessories, system tools, disk cleanup, Click OK (Safe)
4.) Run scandisk (Short version)
5.) Scandisk on XP?
Click on My Computer, select Drive that XP is on, RIGHT click on BLANK place, select properties, then tools at top tab, click check now, check box automattically fix system errors, click start,
then test. Turn all running programs off. Reboot computer so you have all your RAM

softworks · Post by **softworks** » Mon Feb 25, 2002 8:16 pm

No change...

Lobo · Post by **Lobo** » Mon Feb 25, 2002 8:17 pm

Well it's not XP, so I would format

softworks · Post by **softworks** » Mon Feb 25, 2002 8:19 pm

Format what?

Lobo · Post by **Lobo** » Mon Feb 25, 2002 8:22 pm

reinstall XP, maybe some files did not get on it, make sure disk is clean, but before that, hook 1 of your other puters up to that phone line and see if they are still as fast, if they are reformat, if they are not, then it is connection

softworks · Post by **softworks** » Mon Feb 25, 2002 8:23 pm

But by reinstalling XP, I will lose all my files. Right?

Lobo · Post by **Lobo** » Mon Feb 25, 2002 8:28 pm

Transfer your files to one of your other puters
