faster speed

[stevebakh]

hey. I wanted to know what download speeds other people have with 128K connections. On average I get 30 - 40Kbps. It like starts off real high then frops to 30. I've tried the tweaks from the speedguide, but I haven't noticed much difference. Any idea on how to speed up any more?¿

i need to know what verison of windows you are running?? also click on tcp analyzer and cut and paste all the info below ip information. ;)

[stevebakh]

hey... ermmm it's in the profile. I'm usin Win2000 Pro [hardware mentioned in profile] but modem is built into cable tv box! i got the results here of that test tcpoptimiser

TCP options string = 020405b40103030201010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
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)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

are you connected usb or network card if usb if you can't connect through network card call company and see if you can get a cable modem. also for rwin try 51100,64240, i will give more values later sorry I should've check profile kinda sick allergy stuff.

[mccoffee]

for rwin try this 16834 if you have cable nut installed try thease settings to get cablenut if not you could get here http://www.broadbandnuts.com/software.shtml

[stevebakh]

yeah.... from the box connected through USB. I have a NIC. Would it be faster to run through the NIC?¿ I kept that free so I could share the connection between my two comps. Should I buy a second NIC then and just use one NIC for the internet connection? Nope... I don't have CableNut, yet! Also... could you tell me what "bottleneck" is. I heard somethin bout it and I have an idea from the name... but ain't 100% sure.

thanks

stevebakh once you download Cablenut you might also try the following settings:

DefaultReceiveWindow = 16384
DefaultSendWindow = 16384
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
IgnorePushBitOnReceives = 0
GlobalMaxTcpWindowSize = 11680 or 17520
MaxFreeTcbs = 8000
MaxHashTableSize = 16384
MaxNormLookupMemory = 5000000
SackOpts = 1
SynAttackProtect = 1
Tcp1323Opts = 1
TcpLogLevel = 1
TcpMaxDupAcks = 2
TcpMaxHalfOpen = 100
TcpMaxHalfOpenRetried = 80
TcpRecvSegmentSize = 1460
TcpSendSegmentSize = 1460
TcpTimedWaitDelay = 30
TcpUseRFC1122UrgentPointer = 0
TcpWindowSize = 11680 or 17520
MaxConnectionsPer1_0Server = 40
MaxConnectionsPerServer = 20
DefaultTTL = 128
DisableUserTOSSetting = 0
TcpMaxDataRetransmissions = 6
DefaultTOSValue = 92

Also add th efollowing value to your registry under the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\Parameters

Add a DWORD value named BufferMultiplier and give it a hexidecimal value of 400.

:) :D

yeah get another nic (network card) also a router to share the connection with the other comp. Bottle neck means that when internet traffic goes fine for awhile than slows down due to the fact that there is alot of users on the net at once. it's kind like ur driving on road everything is going smooth untill road construction and every is stuck at that point. Then it clears up after the point or when ppl get off the road I hope that made sense. Download cable nut intsall cablenut try those settings install nic (network interface card) and get router you'll be all set. or if you can't afford router you could setup i.c.s internet connection sharing click on network help in my sig for i.c.s. and router info :D sorry to repeat things just want the best speed for u.

[stevebakh]

that's cool... yeah thanks. I had the basic idea of bottleneck... just needed verifying! i would have to save my wages for a week or two for the router [screw that] I'll probably try the software solution. Thaks for the help... so I'm guessing that my speeds would also increase if I used the NIC rather than the USB port? Makes sense I guess.... thanks a lot! :D

Mr.Coffee, you see the bold statement? How do I increase teh RWIN value? Sorry if this is in the "REAd HERE" thread.
:(

[stevebakh]

hey dude... have you used the reg patches to change some of your values?¿ You can get them from here:

http://www.speedguide.net/Cable_modems/cable_patches.shtml

There are different patches that do different jobs. Just get the ones you think are necessary and it should change your speed when uploadin pages etc...

[mccoffee]

or click on tcpoptimizer in my sig
also I need to know what version of windows you have. also type of connecetion cable, dsl, who is ur internet provider?? they are very important before i give advice. ;)
