Need Help On settings

[aznmutazn]

My sister told me that she posted her information of www.dslreports.com onto their forums and they told her to use this RWIN value - 31944

According to the formula you've provided.. I've gotten 3 different possibilities

58400 and 71540 and 456552

The first one is going by this page

the second one is going by this page
http://forums.speedguide.net/showthread.php?threadid=113043&highlight=tcpoptimizer

The third one is going by the RWIN calculator with values of
1500 for bandwidth
305 for latency
1492 for MSS

This is what the analyzer said before inputting the value my sister gave me using DR.TCP
downloaded from http://www.dslreports.com/

TCP properties for IP = xx.xxx.xx.xxx
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)
Note: Read the Analyzer FAQ if the above is not your IP address.


TCP options string = 020405ac01010402
MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1452
MSS is optimized for PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.

Default Receive Window (RWIN) = 65340
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65340

RWIN is 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)
bandwidth * delay product:

Your RcvWindow limits you to: 2613.6 kbps (326.7 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1045.44 kbps (130.68 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 115 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000







This is what the analyzer gave me after I inputed the RWIN value and restarted

Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)

and currently my computer is set to the last analyzer test I put here.


1. My connection is DSL PPPoE
2. Bellsouth 1500kbps/256kbps
3. The last TCP/IP Analyzer test I just posted
4. Windows XP Service Pack 1

And I have already used the spyware tools

Please tell me what I should change in TCPOptimzer.. all the values.

Below the recommended downloads... there are suggestions to do with with my settings on this post http://forums.speedguide.net/showthread.php?s=&postid=643301#post643301
should I do those?

Thanks very much.:D


<edit>
One more thing....
If there is any other program I should use to make my connection faster.. please tell me.

Oh yea.. I'm behind a router... Linksys wired one.. umm so does that make it routerppoe or winxppoe

I play counter-strike and before I reformated my ping would be about 300, then I set it to OpenGL and it became 90... now its back to around 300 with OpenGL setting..?


This is where the other information I got came from

Welcome to Speedguide aznmutazn:D, the two links you provided are mine and they are the same formula for calculating your RWIN;). If your latency is 305ms using the suggestions I said then you should have an RWIN of 58080. The formula and description of how I show to find your RWIN is the proper way. If you did exactly as it said and checked your latency under a load (while downloading a file) then use these settings in the TCPOptimizer:

Settings tab:

select - DSL PPPoE
check - custom settings
network adapter selection - your NIC
check modify all adapters
maxmtu - 1492
TTL - 64
TCP Receive Window - 58080
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 3
TCP 1323 Options - uncheck both boxes

Other Settings tab:

Max Connections per Server - 10
Max Connections per 1.0 Server - 20
Lan Browsing Speedup - optimized

Then select "Apply Changes" and reboot to take effect.

VERY IMPORTANT TO DO THE FOLLOWING

1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need.

2. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.

3. Make sure you have the latest drivers for your NIC from the manufacturer. Set your NIC duplex mode to 10mb half duplex for Cable, for DSL it is ISP dependent unless you are using a router, if so then set it to 100mb full duplex for both Cable & DSL (the instructions are in my Help & Tips link (http://forums.speedguide.net/showthread.php?s=&threadid=73799)). If you are using a router make sure you have the latest firmware.

4. Clear your temporary internet files.

5. Power cycle your modem, unplug it for atleast 15 seconds.

6. Download and update then do a scan with SpyBot 1.2 (http://beam.to/spybotsd) & Ad Aware 6.0 (http://www.lavasoftusa.com/support/download) to remove any spyware then install and update SpywareBlaster 2.5.3 (http://www.wilderssecurity.com/spywareblaster.html) to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES.

7. Make sure you do the faster web page tweak in my Help & Tips link (http://forums.speedguide.net/showthread.php?s=&threadid=73799).
