ciao ragazzi!! premetto che sono inespertissimo-ho un modem pirelli netgate voip-linea tiscali 8 mega-S.O. windows XP
non so da che parte cominciare per settare chi mi aiuta??

TCP options string = 0204059601010402

MTU = 1470
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.

MSS = 1430
Maximum useful data in each packet = 1430, which equals MSS.

Default TCP Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 65535

Note: TCP 1323 Options need to be enabled for RWIN over 2^16 (65535). Windows 9x might also need the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
503360 (MSS x 44 * scale factor of 8)
251680 (MSS x 44 * scale factor of 4)
125840 (MSS x 44 * scale factor of 2)
62920 (MSS x 44)

bandwidth * delay product (Note this is not a speed test):

Your TCP Window limits you to: 2621 kbps (328 KBytes/s) @ 200ms
Your TCP Window limits you to: 1049 kbps (131 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 (0)
