Lobo..here you go..this is in regards to my question earlier regarding post
Topic: Tweaks and RoadRunner (cincinnati

Do you think I need to change anything??

TCP options string = 020405ac01010402

MTU = 1492
MTU seems to be optimized for PPPoE... If you are not on a PPPoE connection, consider increasing your MTU to 1500 for optimal throughput.

MSS = 1452
Maximum useful data in each packet = 1452, which is equal to MSS.
MSS is optimized for PPPoE. If you are not on a PPPoE connection, consider increasing your MTU value.

Default Receive Window (RWIN) = 65340
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65340
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8)
255552 (MSS x 44 * scale factor of 4)
127776 (MSS x 44 * scale factor of 2)
63888 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 2613.6 kbps (326.7 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1045.44 kbps (130.68 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 115 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

lobo

I dont see anything like

DWORD
or
Tcp1323Opts
or
PMTUBlackHoleDetect
in my registry

I went to the page http://www.speedguide.net/Cable_modems/cable_registry.shtml like you said and look at the part that describes this..but I dont have it in my registry..and I havent hacked into the reg..so I know its not something that I did

Am I looking for the wrong key/value?

OK , rather than have you fooling around in registy do this and on Dr. TCP where it says time stamping select-YES, An yes if you go to the page above it's on there but do this:
Please go to this http://www.dslreports.com/front/drtcp.htmlRL
Download DR. TCP to your desktop
Where it saids adapter settings, select your adapter
Where it says Windows sclaing- yes
Where it says Selective Acks-yes
Path MTU Discovery - yes
Black Hole Detection - No
TTL-64 or 32 (up to you)

Where it says Time Stamping, select yes
The choices I give above will not affect speed, click apply
Reboot for changes to take affect

Do not change any numbers in this box unless you know what you are doing.
A blank box only means that the default setting is being used
