Sorry sTCP options string = 0204057801010402

MTU = 1440
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

MSS = 1400
Maximum useful data in each packet = 1400, which equals 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) = 35000
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 35000
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
515200 (MSS x 46 * scale factor of 8)
257600 (MSS x 46 * scale factor of 4)
128800 (MSS x 46 * scale factor of 2)
64400 (MSS x 46)

bandwidth * delay product:
Your RcvWindow limits you to: 1400 kbps (175 KBytes/s) @ 200ms
Your RcvWindow limits you to: 560 kbps (70 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 50 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 01011100
Precedence (priority) = 010 (immediate)
Delay = 1 (low delay)
Throughput = 1 (high throughput)
Reliability = 1 (high reliability)
Cost = 0 (normal cost)

till no joy as you can see - I changed it to 1470 and still no change. Let me know what you think (I did reboot and I did go in and recheck that I typed it right and I had done it right). Thanks
