where can I get the cablenut program I just got cable internet need help tweaking

[cablenut]

I have no idea

[MadDoctor]

Hello Ruben22. Welcome to SG. You can find the software at:
http://www.cablenut.com. Take your time. Back up any file before you change it (to include your registry). No need to rush into a tweak. Come back tomorrow when there are some people around to help you.

Know what you want to do before you try doing it.

Good Luck!

Doc

cablenut, you are playin with people too much on here lol

Ruben22

I might recommend lookin at lobo's help page, the link to it is in my sig

And, yes, Welcome to SG

[Ruben22]

I installed that cablen nut and this is what I got on the test TCP options string = 020405b40103030001010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.

Default Receive Window (RWIN) = 8760
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 8760
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)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 350.4 kbps (43.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 140.16 kbps (17.52 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.

MTU Discovery (RFC1191) = ON

Time to live left = 111 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000


what elses do I do??

[lance-tek]

in the cablnut shortcut on your desktop, install the CCS files and select your OS and type of connection, reboot and repost

[Ruben22]

ok I did what you told me to do and now I got this

TCP options string = 020405b40103030101010402

MTU = 1500

MSS = 1460

Your RcvWindow limits you to: 2055.68 kbps (256.96 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 31 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000


is that ok or do I need to change something?

[cablenut]

Looks Ok Now

[Ruben22]

hey thank for all your help hey I changed the rwin numer just to see what the diference was and this is what I got

It seems to download much faster too I tried it at download.com and I got downloads up to 560 kb/s WOW and I tested it on dslreports.com/test and It also went up is it ok if I leave that rwin number or shoudl I change it back to what I had it?

[lance-tek]

if you are happy with what you have then leave it I like to play around some times and I try new RWIN all the time. I also play with other settings however, I do not recommend anyone tryin it unless they know what they are doing

[Lobo]

Where did he test at, oh no
