View Full Version : Newbie with DSL need help

03-14-01, 09:28 AM
I did the speed test and here is my result.
TCP options string = 0204058601010402

MTU = 1454
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1414
Maximum useful data in each packet = 1414, 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) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535
Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
520352 (MSS x 46 * scale factor of 8)
260176 (MSS x 46 * scale factor of 4)
130088 (MSS x 46 * scale factor of 2)
65044 (MSS x 46)

bandwidth * delay product:
Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

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

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000

I know that should be better so what do i need to change or do and how?

Thanks for your help

Turn timestamps on -YES on Dr. Tcp, 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,
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 :)

And no that is not a speed test, but a tweak tester :eek:

Will that increase my download speed?
Other than that Lobo what else should i do?
for the MTU nad MSS any advice?

Thanks Lobo
