SG Broadband Community

Hi everyone.....new guy here. Been trying out your tips and tricks. Wondered if i was doing ok with my @home connection. Im running ME.

TCP options string = 020405b40103030301010402

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) = 373360
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 46670
For optimum performance, consider changing RWIN to 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: 14934.4 kbps (1866.8 KBytes/s) @ 200ms
Your RcvWindow limits you to: 5973.76 kbps (746.72 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = OFF

Time to live left = 54 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000



Ive been trying diff settings and downloading the star wars demo from happypuppy.com. Im getting around 700 to 800 KB/sec with download accelerator. I think its pretty good....but i would still like to do better if possible. You guys seem to know your **** so i figured if anyone can help me it would be here..thanks

You need to turn MTU Discorvey on, In this program it's called Path MTU Discovery, do this:
Download lastest version of Dr. TCP from http://www.dslreports.com/front/drtcp.html
This is just a shortcut to your registry.
1.) Select your adapter
2.) Window Scaling- Yes
3.) Time stamping - No
4.) Selective Acks - Yes
5.) Path MTU Discovery - Yes
6.) Max Duplicate ACKS - 3
7.) TTL - 32 -64 (Nothing to do with speed)
8.) Blank boxes only mean default value is being used
9.) Do not change numbers in these boxes unless you know what you are doing.

Thanks for the help.

Just for the heck of it you might raise RWIN to 373760 in Dr. TCP, if you don't like it, switch back
