just switched to opt. online

win xp

10000/1000

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

TCP options string = 020405b40103030101010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 94900
RWIN Scaling (RFC1323) = 1 bits (scale factor of 2)
Unscaled Receive Window = 47450
RWIN is not fully optimized (even though it is a comparatively large number). The unscaled RWIN value is lower than it should be, which can affect your connection to some servers. Also, RWIN being close above 65535 does not justify the header overhead of scaling. You might want to use one of our recommended RWIN values below.

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)
64240 (MSS x 44)
bandwidth * delay product:

Your RcvWindow limits you to: 3796 kbps (474.5 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1518.4 kbps (189.8 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 119 hops

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

speed test was 9210/947. can i get any quicker??

Try the following settings in CableNut:

DefaultReceiveWindow = 921600
DefaultSendWindow = 128000
DisableAddressSharing = 1
InitialLargeBufferCount = 200
InitialMediumBufferCount = 480
InitialSmallBufferCount = 640
LargeBufferSize = 819200
MaxFastTransmit = 64000
MediumBufferSize = 150400
PriorityBoost = 0
SmallBufferSize = 12800
TransmitWorker = 32
FastSendDatagramThreshold = 4096
EnableFastRouteLookup = 1
EnablePMTUDiscovery = 1
IgnorePushBitsOnReceive = 0
GlobalMaxTcpWindowSize = 128480
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 1
TcpLogLevel = 1
TcpMaxDupAcks = 3
TcpMaxHalfOpen = 100
TcpMaxHalfRetried = 80
TcpRecvSegmentSize = 1460
TcpSendSegmentSize = 1460
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 128480
MaxConnectionsPer1_0Server = 20
MaxConnectionsPerServer = 10
DefaultTTL = 64
DisableUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 240

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. 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 (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).

8. If you have Zone Alarm as a firewall uninstall it then visit Zonelabs.com (http://www.zonelabs.com/store/content/home.jsp) for further instructions on removing it's left over junk.

9. Install Outpost Firewall (http://www.agnitum.com/products/outpost) or Sygate Firewall (http://www.sygate.com), 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 (http://www.grisoft.com/us/us_dwnl_free.php) is an excellent FREE AV app.

For OOL set your NIC duplex mode to 100mb full.

:cool:

Yep.

:nod:

[fastrek82]

my speed test is 9210/950 can i do better or am i just waisting time???

[mnosteele52]

Your at 90% of your caps so you aren't going to get any better. I gave you the above settings because they are what works the best for most OOL users and it will help stabilize your connection.

:cool:

[fastrek82]

thanks for yer help......;)

[fastrek82]

i did the cablenut tweaks above it cut my D/L sp in half very bad.....

[mnosteele52]

That's off it improves most OOL users connections. Can you please post a TCP/IP Analyzer test with those settings and a speed test from the OOL FTP test in my help & tips link?

:cool:
