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..

See help page in sig below and then ask me what you need

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..

hmm...

didnt change anything...

i dont know what im doing... plz help out.. im outa ideas...

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.

Ecko · Post by **Ecko** » Mon May 14, 2001 11:24 pm

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

Ecko · Post by **Ecko** » Mon May 14, 2001 11:27 pm

"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"

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

EvilAjax · Post by **EvilAjax** » Mon May 14, 2001 11:52 pm

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?

Are you noticeing any speed increase?

Ecko · Post by **Ecko** » 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....

Ecko · Post by **Ecko** » Tue May 15, 2001 12:36 am

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?

Lobo · Post by **Lobo** » Tue May 15, 2001 9:38 am

Half duplex or auto speed detect

[ 05-15-2001: Message edited by: Lobo ]

Ecko · Post by **Ecko** » Tue May 15, 2001 6:47 pm

why not in full duplex?

so 100 half duplex?

Lobo · Post by **Lobo** » Tue May 15, 2001 6:48 pm

Because thats wrong

Lobo · Post by **Lobo** » Tue May 15, 2001 7:04 pm

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
