my previous post had too many so i started a new one..
i got cablenut 4.0 and updated it to 4.02
i got it from microsystems and the reg patches from here...
and what is it that i needed to change.. was little confused...
and to what settings i need to set it at..

TCP options string = 020405b4010303020101080a000000000000000001010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1448, which is less than MSS because of Timestamps, or other TCP/IP options used.
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)
bandwidth * delay product:
Your RcvWindow limits you to: 10278.4 kbps (1284.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4111.36 kbps (513.92 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 50 hops
TTL value is ok.
Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349)= 00000000
This is b4 i made my speed tweaks.. be back with the patches applied..

In Cablenuts adjuster you may change RWIN, in W2K 3 places on adjuster, 1-box Default Recieve Window, 2. box- GlobalmaxTcpWindowSize 3. box-TcpWindowSize,
try 1 at a time 513920, 522680, 524176, save to registry at bottom and reboot each time you change a value

Here's the shot of the 2k adjuster.

so i start with no setting in cablenut adjuster? or use the fast win2k.css and change those 3 setting you described...

and im confused with the 3 settings?
513920, 522680, 524176? where do i put these?
what value do i set 1-box Default Recieve Window, 2. box- GlobalmaxTcpWindowSize 3. box-TcpWindowSize?
im still learning all these, so i ask stupid questions.... sorry

Put the each suggested RWIN in those three places, one reboot at a time. (example: 511104 in all three places)

nullwhat do you think of these?
TCP options string = 020405b40103030301010402
MTU = 1500

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.
Default Receive Window (RWIN) = 524176

For optimum performance, consider changing RWIN to a multiple of MSS.

Are you noticeing any speed increase?
Posted: Tue May 15, 2001 12:19 am

not really... it actually seems slower... b4 i changed the 3 settings to 524176 i can download the SP1 off microsoft at 350kps+
now it was going at 240kpbs or less...
will try 522680 then 513920

im getting over 440kps... but at happypuppy.com... it seems a little bit slower....

also..
i have a SOHO 10/100 ethernet card... and in the properties... i can set the speed to 100 full duplex.. is this good? the options are:
100 full duplex
100 half duplex
10 full duplex
10 half duplex
auto speed detect
would this effect my up/downloads or should i just leave it at auto speed detect?

Half duplex or auto speed detect

why not in full duplex?
so 100 half duplex?

Because thats wrong

The setting on your NIC card is not the same as the one in BIOS, that one should be full if you want to talk and hear at same time
