Requiring assistance in tweaking

[Raymomofo]

Hello. I would appreciate any trouble in tweaking my internet connection.

1. I have a DSL PPPoE connection.
2. I have Sympatico High Speed Internet. My advertised speed is 10 mbps
3. Current Settings:

TCP options string = 020405a00103030201010402
MTU = 1480
MTU is optimized for Windows XP PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1440
MSS is optimized for Windows XP PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.
Default Receive Window (RWIN) = 255552
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 63888

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
506880 (MSS x 44 * scale factor of 8)
253440 (MSS x 44 * scale factor of 4)
126720 (MSS x 44 * scale factor of 2)
63360 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 10222.08 kbps (1277.76 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4088.832 kbps (511.104 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 56 hops

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

4. Operating System = Windows XP Home Edition

Thank you in advance for any help

Try these settings:

Download the TCP Optimizer (http://www.speedguide.net/files/TCPOptimizer.exe) and try the following settings.

Settings tab:

select - DSL PPPoE
check - custom settings
network adapter selection - your NIC
check modify all adapters
maxmtu - 1480
TTL - 64
TCP Receive Window - 63360
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 2
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. 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. DO NOT CONNECT YOUR MODEM VIA USB!!

4. Clear your temporary internet files.

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

6. Download, update and scan with SpyBot S&D (http://majorgeeks.com/download2471.html) EXACTLY as I explain HERE (http://broadbandnuts.com/drtweak/index.php?board=4;action=display;threadid=41) & Ad-aware (http://lavasoft.element5.com/support/download) EXACTLY as I explain HERE (http://broadbandnuts.com/drtweak/index.php?board=4;action=display;threadid=40) to remove any spyware then install and update SpywareBlaster (http://www.javacoolsoftware.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).

8. If you have Zone Alarm as a firewall uninstall it and search your pc for the left over files.

9. Install Sygate Firewall (http://www.sygate.com) they have a FREE and Pro version.

10. Scan for viruses with your antivirus app, if you do not have one get one IMMEDIATELY, I recommend using AVG 6.0 (http://www.grisoft.com/us/us_dwnl_free.php) it is an excellent FREE AV app. Make sure you set it up EXACTLY as I explain HERE (http://broadbandnuts.com/drtweak/index.php?board=4;action=display;threadid=38&start=0).

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