Tweak Me Please.

Post by ps2wiz »

Bellsouth DSL 6Mbps/512K.
U.S. Robotics USR5461 Router
Windows XP Pro

TCP options string = 020405ac

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 your MTU value.

Default TCP Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 65535

Note: TCP 1323 Options need to be enabled for RWIN over 2^16 (65535). Windows 9x might also need the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values 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 (Note this is not a speed test):

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

MTU Discovery (RFC1191) = ON

Time to live left = 117 hops
TTL value is ok.

Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = OFF
IP type of service field (RFC1349) = 00000000 (0)




Thanks in advance!

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

General Settings tab:
Custom settings - check
Modify All Network Adapters - check
network adapter selection - your NIC
MTU - 1492
TTL - 64
TCP Receive Window - 63888
MTU Discovery - Yes
Black Hole Detect - No
Selective Acks - Yes
Max Duplicate ACKs - 2
TCP 1323 Options:
Windows Scaling - uncheck
Timestamps - uncheck
Advanced Settings tab:
Max Connections per Server - 10
Max Connections per 1.0 Server - 20
LocalPriority - 5
Host Priority - 6
DNSPriority - 7
NetbtPriority - 8
Lan Browsing speedup - optimized
QoS: NonBestEffortLimit - 0
ToS: DisableUserTOSSetting - 0
ToS: DefaultTOSValue - 240
MaxNegativeCacheTtl - 0
NetFailureCacheTime - 0
NegativeSOACache Time - 0
LAN Request Buffer Size - 32768
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. 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.
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 EXACTLY as mnosteele has explained HERE & Ad-Aware SE 1.06 EXACTLY as mnosteele has explained HERE to remove any spyware then install and update SpywareBlaster 3.4 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 log for us to look at.
7. Make sure you do the faster web page tweak in our Help & Tips 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, it's FREE and uses next to no resources.
10. Do a FREE online virus scan from Kaspersky Webscan, make sure to check the option to use the EXTENDED DATABASE.
11. Make sure you have ALL of the latest Windows Updates.

Bandwidth tests yielded the same speeds, but more stable. Less flucatuations in tests.

Can you help me too?
I have absolutely no clue what any of this stuff means, as the technical terminology is WAY out of my league, but this is what the SpeedGuide.net TCP/IP Analyzer said:


Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.2) Gecko/20060308 Firefox/1.5.0.2

TCP options string = 0204056401010402

MTU = 1420
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.

MSS = 1380
MSS is not optimized for broadband. Consider increasing your MTU value.

Default TCP Receive Window (RWIN) = 1380
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 1380

RWIN seems to be set to a very small number. If you're on a broadband connection, consider using a larger value.
RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
507840 (MSS x 46 * scale factor of 8)
253920 (MSS x 46 * scale factor of 4)
126960 (MSS x 46 * scale factor of 2)
63480 (MSS x 46)

Your TCP Window limits you to: 55.2 kbps (6.9 KBytes/s) @ 200ms

Well, my connection appears to be slower than ever, and I am getting "Server Timed Out" errors off the wall. The Task Manager still reports that less that 0.5% of my network is being used at any time, and Steam just totally died and I lost EVERYTHING it had. All those games, all those maps I made... all gone.

Thank you. Thank you very much. :cry:
