ive never had dsl until a few days ago so if you could give me a little direction i would appreciate it...

TCP options string = 020405ac01010402

MTU = 1492
MTU seems to be optimized for PPPoE... If you are not on a PPPoE connection, consider increasing your MTU to 1500 for optimal throughput.

MSS = 1452
Maximum useful data in each packet = 1452, which is equal to MSS.
MSS is optimized for PPPoE. If you are not on a PPPoE connection, consider increasing your MTU value.

Default Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8)
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
63888 (MSS x 44)

Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

Looks ok. Hows your speed, http://atl.speakeasy.net/ with RWIN 65535 ? What speeds are you paying for, down and upload? Another RWIN to try is 63888 or 32767

LuiKhang what are your rated speeds from your ISP? You need to make your RWIN a multiple of your MSS (which for you is 1452) i.e. 1452 x 22 = 31944. Try RWIN values of 31944, 40656, 50820 or 63888. Also try a speed test from the link in my sig it will give you alot of good information.

tested...

1234 down
128 up

company claims 1500/256, i already got it from 500 to where it is now by downloading sgtcpipo, and just selected optimal settings for DSL.

65535 got my up's to 200 but how could a get a better down?

Try lowering your RWIN and respeed test to see if you get better speed. Start with the lowest value and move up from there, till your speed doesn't improve, then drop back 1 RWIN value.
31944, 40656, 50820 or 63888
I use 32767 and get my best from that.

Use this speed test as it is closest to you, http://atl.speakeasy.net/

Post the Graph URL from speed test.

is there a version past 1.0 of the optimizer? my mtu is set to 1500 but the analyzer says its 1492. And what should i click under network, dial up adapter, or my network card?
Finally, how do i find out if im ppp or normal

Musclemanfu2 · Post by **Musclemanfu2** » Tue May 14, 2002 10:25 pm

Is your ISP BellSouth? Do your use a router? Do you have to connect(log-on) to DSL? Look in Control Panel-Add/Remove to see if Enternet or Winpoet is listed or Start-Programs to see if Winpoet is listed as PPPoE software.

My service is bell south instant access dsl, i have a networking 2wire home portal deal that connects to my netgear card via cat5. the service says 1500/256, but i am getting 1200/210. i dont see any pppoe files in start or control panel, the network box stays connected and its logged on the minute i start my pc. the best results for rwin is when it is set in the mid 60k's

LuiKhang · Post by **LuiKhang** » Thu May 16, 2002 9:28 pm

Is there a version of tcp/ip o above 1.00, because i click dsl and every time a restart it has the cable button fixed, i dont think it hurts anything, its just annoying. And it sounds like a stupid question, but, how do i know if i have a pppoe connection or a regular, it goes from phone to always on modem/network box to netgear 10/100 via cat5 (pci)...I have no clue about this stuff

please help

LuiKhang turn in ICQ and I'll help you.

The latest version is 1.0.

Don't be too concerned about the radio button staying in the 'cable' position -- that is just the default position for the program. It is of little consequence.

You most likely have PPPoE -- otherwise it would be very unlikely that you would find an MTU of 1492.

Look under Network Properties and you will generally find your answer.

I messed around with my pppoe routher adsl (claims=1500/256)(getting 1220down/210up) before a leave well enough alone i would like to know how i should do with these settings, just tell me on or off and ill be set

And should i click modify all network adapters?
I know i am being annoying but please bear with me
