Welcome to Speedguide:D, use the following settings in CableNut:

DefaultReceiveWindow = 768000
DefaultSendWindow = 65536
DisableAddressSharing = 1
InitialLargeBufferCount = 100
InitialMediumBufferCount = 240
InitialSmallBufferCount = 320
LargeBufferSize = 81920
MaxFastTransmit = 64000
MediumBufferSize = 15040
PriorityBoost = 0
SmallBufferSize = 1280
TransmitWorker = 32
FastSendDatagramThreshold = 4096
EnableFastRouteLookup = 1
EnablePMTUDiscovery = 1
IgnorePushBitsOnReceive = 0
GlobalMaxTcpWindowSize = 64240
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 0
TcpLogLevel = 1
TcpMaxDupAcks = 2
TcpMaxHalfOpen = 100
TcpMaxHalfRetried = 80
TcpRecvSegmentSize = 1460
TcpSendSegmentSize = 1460
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 64240
MaxConnectionsPer1_0Server = 20
MaxConnectionsPerServer = 10
DefaultTTL = 64
DisableUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 92

Also do the following:

1. Under your LAN connection - properties - general tab, uninstall all the protocols there except TCP/IP Internet Protocol.

2. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.

3. 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=85224)).

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 (http://beam.to/spybotsd), anything checked in red is spyware and safe to remove.

Please post back and let me know how the settings worked for you.:D ;)

i ran a series of test after going through all the procedures outlined.

Here are some test results from the Cali (San Jose) site

1. 1817/261
2. 1462/221
3. 1043/246
4. 1451/246

I then removed the cablenut settings and tested again.

1. 2374/303
2. 1556/316
3. 894/273
4. 1090/285
5. 1984/385

These results seem fairly inconclusive to me due to such a wide variance of of bandwidth's. All test were completed within a matter of minutes of each other. This could be due to my side.....I'll try again tomorrow. Any other suggestions?

check ping stability :(

Are you deleting your browser cache before running each speed test?

I always clear my temporary internet files as well as my cookies and offline content after each test. I have also tested the ping stability and does not vary by more than a few ms. I ran the TCP analyzer and everything was configured ok. I'm not to sure what else to do!!!

see on your speed test results
compare max & min value
max are more than 2x
in both explained

some thing is wrong with data flow
ping & traced side of speed tests
