RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:

256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
bandwidth * delay product (Note this is not a speed test):

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

Try thease in the sg optmizer below me to download and install

check - custom settings
network adapter selection -
check modify all adapters
maxmtu 1500
TTL - 64
TCP Receive 32120
MTU Discovery - yes
Black Hole Detect - no
Selective Acks - yes
Max Dup ACKs - 2
TCP 1323 nothing is checked

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.


1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need. For a stand alone pc all you need is Internet Protocol TCP/IP.

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. Clean out your temporary internet files with CrapCleaner (http://www.ccleaner.com).

5. Power cycle your modem i.e. unplug it for at least 15 seconds.

6. Download, update and scan with SpyBot S&D 1.4 (http://majorgeeks.com/download2471.html) EXACTLY as mnosteele has explained HERE (http://broadbandnuts.com/drtweak/index.php?board=4;action=display;threadid=41) & Ad-Aware SE 1.06 (http://lavasoft.element5.com/support/download) EXACTLY as mnosteele has explained HERE (http://broadbandnuts.com/drtweak/index.php?board=4;action=display;threadid=40) to remove any spyware then install and update SpywareBlaster 3.4 (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. If these 2 programs find a lot of things then please post a HijackThis 1.99.1 (http://www.majorgeeks.com/download3155.html) log for us to look at.

7. Make sure you do the faster web page tweak in our Help & Tips (http://broadbandnuts.com/index.php?page=tiptrix) page.

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

9. Install Kerio Personal Firewall 2.1.5 (http://www.321download.com/LastFreeware/page7.html#Kerio%20Personal%20Firewall), it's FREE and uses next to no resources.

10. Do a FREE online virus scan from Kaspersky Webscan (http://www.kaspersky.com/beta), make sure to check the option to use the EXTENDED DATABASE.

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