Hello All,
I have just started reading SG. And thank you all for making this board so great. I have a few questions as a newbie. My connection is through school's VPN, where I have to log in everytime I restart my computer. But since I live in an apartment, I have to use Charter's cable connection. (this is U. Wisconsin - Madison) I was wondering if I can tweak my connection. I have installed cablenut adjuster proggy, but I have no clue what to fill in for most of the blanks. I have tried some from searching this forum. But seems very unrealiable. Here are my comp. specs for now. I will be getting a new computer soon as my primary. And this one will become my server.
CPU. AMD Tbird 1.33
Ram 768
Network Intel Management PRO+ (original windows drivers)
2xMaxtor diamond max pro 7200 @ raid 0
Windows 2k ADV Server.
Motorola Surfboard 4100
(anything else needed)

This is what I get.

TCP options string = 0204055001010402

MTU = 1400
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1360
Maximum useful data in each packet = 1360, which is equal to MSS.
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 64240
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 64240
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
522240 (MSS x 48 * scale factor of 8)
261120 (MSS x 48 * scale factor of 4)
130560 (MSS x 48 * scale factor of 2)
65280 (MSS x 48)

bandwidth * delay product:
Your RcvWindow limits you to: 2569.6 kbps (321.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1027.84 kbps (128.48 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 36 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000



I would like to know what I need to fill in for those blanks in Cablenut. And how I can change the MTU to max. Also is it necessary to use the Intel drivers for my network card. I read things say that it might improve performance, but it might crash more. After installing I know there will be more setting changes I can do to the NIC. I will apply stand alone IRQ tweak for my NIC after hearing from you guys. And also is there a way to write a script to auto login without have to click at start up? I know this is a lot of questions. Just want to say thanks for reading and answering my post ahead of time. Thank you
Andrew

I would click on delete Cablenut tweaks at bottom of adjuster, REBOOT, then since you have already installed Cablenut, start on help thread below in signature where it says download and install SG's patches, you can save settings in adjuster, directions on help thread below along with direction to boost up MTU, which NIC driver you use is up to you:)
