Ciao raga e auguri.
Che ve ne pare credo che devo apportare qualche piccola modifica.Alice 2 mb (non ancora messa in fast) cmq i ping su maya.ngi.it sono 55ms min. e 75ms max. su google è 100 (solo oggi pero) da quando ci so lavori il pomerigio vado a 200ms-150ms per modificare il MTU sono andato sia sul modem 320T (dlink) che su Dr.Tcp.
Speed Down 1736.70 Kbps ( 1.7 Mbps )
Speed Up 291.99 Kbps ( 0.3 Mbps )


TCP options string = 020405ac0103030201010402

MTU = 1492
MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.

MSS = 1452
MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value.

Default TCP Receive Window (RWIN) = 255552
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled TCP Receive Window = 63888

RWIN is a multiple of MSS
Other RWIN values that might work well with your current MTU/MSS:
511104 (MSS x 44 * scale factor of 8)
255552 (MSS x 44 * scale factor of 4) <-- current value
127776 (MSS x 44 * scale factor of 2)
63888 (MSS x 44)

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

Your TCP Window limits you to: 10222 kbps (1278 KBytes/s) @ 200ms
Your TCP Window limits you to: 4089 kbps (511 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 106 hops
TTL value is ok.

Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 00000000 (0)
