Topic: Cablenut & AT&T 6 Mbps

[Curt]

I'm using the T3 settings w/ Windows XP in Cablenut with my AT&T high speed Internet service. The speed is 6 Mbps. Is this the best setting for me to use?

I would use ool one or the 20mbs and above try them both see what works better.

These are the Cablenut settings that are working best for me:

DefaultReceiveWindow = 921600
DefaultSendWindow = 102400
DisableAddressSharing = 1
InitialLargeBufferCount = 200
InitialMediumBufferCount = 480
InitialSmallBufferCount = 640
LargeBufferSize = 819200
MaxFastTransmit = 64000
MediumBufferSize = 150400
Priority Boost = 0
SmallBufferSize = 12800
TransmitWorker = 32
FastSendDatagramThreshhold = 1024
EnableFastRouteLookup = 1
EnablePMTUDiscovery = 1
IgnorePushBitsOnReceives = 0
GlobalMaxTcpWindowSize = 128480
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 1
TcpLogLevel = 1
TcpMaxDupAttacks = 2
TcpMaxHalfOpen = 100
TcpMaxHalfOpenRetired = 80
TcpRecvSegmentSize = 1460
TcpSendSegmentSize = 1460
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 128480
MaxConnectionsPer1_0Server = 20
MaxConnectionsPerServer = 10
DefaultTimeToLive = 64
DefaultUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 240

I'm now using the default OOL 10000 1000.ccs file located in CABLENUT_UPDATE\WinXP_2K_CABLE and my downloads and web surfing seem to be faster than the above settings:
