Lost My Settings

Post by iflog »

Don't ask me how. I just went to check my Cablenut settings and all were gone.

TCP properties for IP = ()
Browser/OS = Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8.1) Gecko/20061010 Firefox/2.0
Notes: Read the Analyzer FAQ if the above is not your IP address.
TCP options string = 020405b40103030101010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default TCP Receive Window (RWIN) = 128480
RWIN Scaling (RFC1323) = 1 bits (scale factor of 2)
Unscaled TCP Receive Window = 64240

RWIN is a multiple of MSS
Other RWIN values 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) <-- current value
64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 5139.2 kbps (642.4 KBytes/s) @ 200ms
Your TCP Window limits you to: 2055.68 kbps (256.96 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 53 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 01011100 (92)
Precedence (priority) = 010 (immediate)
Delay = 1 (low delay)
Throughput = 1 (high throughput)
Reliability = 1 (high reliability)
Cost = 0 (normal cost)
Check bit = 0 (correct, 8th checking bit must be zero)

DiffServ (RFC 2474) = No valid DiffServ equivalent. See the TCP Optimizer documentation, or RFCs 2474, 2475, 2597, 2598, 2873.

You can use TCP Optimizer with RWIN set to 64240.

You can use the Cablenut calculation page:
