Help tweaking

johnnymunn · Post by **johnnymunn** » Fri Apr 16, 2004 9:49 pm

Hi I'm using Win98SE, high speed cable with Shawcable and using Linksys router. I have already ran TCPOptimizer and Cablenut with 98 settings. Thank you for any help.

TCP options string = 020405b401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 64240
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 64240

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
bandwidth * delay product:

Your RcvWindow limits you to: 2569.6 kbps (321.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1027.84 kbps (128.48 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 43 hops

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

sorry also read the static ip guide below me aslong as read1st for more tips

Try these settings in the TCPOptimizer:

Settings tab:

select - cable
check - custom settings
network adapter selection - your NIC
check modify all adapters
maxmtu - 1500
TTL - 64
TCP Receive Window 75920
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 2
TCP 1323 Options - check Windows Scaling only

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. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer and set your duplex mode to "auto". 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 & Ad Aware 6.0 to remove any spyware then install and update SpywareBlaster 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.

8. If you have Zone Alarm as a firewall uninstall it then visit Zonelabs.com for further instructions on removing it's left over junk.

9. Install Outpost Firewall or Sygate Firewall, both have FREE and Pro versions and are heads above ZA.

10. Scan for viruses with your antivirus app, if you do not have one get one IMMEDIATELY, AVG 6.0 is an excellent FREE AV app.

11. Make sure you have ALL of the latest Windows Updates.

Mccoffee,
The computer seems to be pretty good, I was reading read1st and in the settings for cablenut for win98se all the fields are filled when I run cablenut I only have about 6 settings filled. Should I use those settings? Is there any room for improvements.
Thank you for your help.

How's the speed ??

johnnymunn · Post by **johnnymunn** » Wed Apr 21, 2004 7:44 pm

using the SG speed test I get somewhere in between 632 and 971 kbps.

mccoffee · Post by **mccoffee** » Wed Apr 21, 2004 8:23 pm

http://www.testmyspeed.com/speedtests/international.htm this would give you better resaults try to pick a server close to you and let me know the average the sg speed test isn't that accruate considering you are in the great white north

johnnymunn · Post by **johnnymunn** » Wed Apr 21, 2004 8:40 pm

running the test only 2 times I got 527 and 651 kbps.

mccoffee · Post by **mccoffee** » Wed Apr 21, 2004 9:22 pm

try 126480 where i said 64240 with tcpopts123 set to 1

johnnymunn · Post by **johnnymunn** » Wed Apr 21, 2004 11:35 pm

It's terrible now I've got 174 kbps.

mccoffee · Post by **mccoffee** » Wed Apr 21, 2004 11:59 pm

Go back to the 64240 with tcpopts123 set to 0

tekki · Post by **tekki** » Thu Apr 22, 2004 12:00 am

Try these values:

GlobalMaxTcpWindoSize - leave blank
DefaultRecvWindow - leave blank
DefaultTOS - 127
Tcp1323Opts - 1

Try speed testing using FTP / HTTP Speed Test and let me know what results you get

mccoffee · Post by **mccoffee** » Thu Apr 22, 2004 12:01 am

He is using windows 98 it doesn't have a self tunning stack

tekki · Post by **tekki** » Thu Apr 22, 2004 12:09 am

mccoffee wrote:He is using windows 98 it doesn't have a self tunning stack

That completely slipped by me... Then try the following:

GlobalMaxTcpWindoSize - 32120
DefaultRecvWindow - 32120
DefaultTOS - 127
Tcp1323Opts - 0
MaxDupAcks - 2

Sorry about that- Thanx for pointing that out mccoffee

johnnymunn · Post by **johnnymunn** » Thu Apr 22, 2004 12:16 am

do I try this or isn't it worth it?

mccoffee · Post by **mccoffee** » Thu Apr 22, 2004 12:17 am

You could try 32120 just to see it won't hurt or harm

johnnymunn · Post by **johnnymunn** » Thu Apr 22, 2004 12:30 am

with tekki's setting it's slower it was at it' fastest before that.

johnnymunn · Post by **johnnymunn** » Thu Apr 22, 2004 12:40 am

I've put it back where it was and the speed at numion.com is 691 kbps

johnnymunn · Post by **johnnymunn** » Thu Apr 22, 2004 12:50 am

I found this speed test what do you think about it?
can I use it?

Tekki, why do you keep suggesting this DefaultTOS value of 127? That is not a valid number.
