TCP options string = 020405b4010303030101080a000000000000000001010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1448, which is less than MSS because of Timestamps, or other TCP/IP options used.

Default Receive Window (RWIN) = 438000
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 54750
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: 17520 kbps (2190 KBytes/s) @ 200ms
Your RcvWindow limits you to: 7008 kbps (876 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 55 hops
TTL value is ok.

Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000



I used the lower RWIN becuase i kept getting lots of packet loss and high pings with the others:sleep:

Turn timestames off, and since helppage was written we have found out RWIN size has nothing to do with packet loss, page will be updated:) :)

Packet loss would be a cable problem somewhere:) :)

[Idolater]

how&where do you turn timestames off? And what value do you recommend for the RWIN size? I have @home cable connection.

[Lobo]

Do you have Cablenuts adjuster

Lobo i called @home told them about my 64% packet loss and they told me to change my rwin to 438000. so i did and now i get no packet loss. Do ya have some other RWINS for me to try

[Lobo]

try, 524176, 530710 and 554800:) :) :)


You can turn off timestamps in adjuster by setting Tcp1323Opts -1
save at bottom, and reboot:) :D :) :)

thanks lobo getting downloads in the 780's now with no packet loss:D :D

Your ISP recommended a RWIN?!?! That's the first time I ever heard of an ISP tweaking their customers... weird!

yeah it was some guy named mike at leval 2 support:eek: :eek: :confused: :confused: :eek: :eek:
