Seems like broadband .. above the 1mbit barrier!

TCP options string = 020405ac01010402
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 MTU to 1500 for maximum throughput.
Default Receive Window (RWIN) = 49368
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 49368

RWIN is a multiple of MSS
Other values for RWIN 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)
127776 (MSS x 44 * scale factor of 2)
63888 (MSS x 44)
bandwidth * delay product:

Your RcvWindow limits you to: 1974.72 kbps (246.84 KBytes/s) @ 200ms
Your RcvWindow limits you to: 789.888 kbps (98.736 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON

Time to live left = 56 hops

TTL value is ok.
Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349) = 11110000

Precedence (priority) = 000 (routine)
Delay = 0 (normal delay)
Throughput = 1 (high throughput)
Reliability = 1 (high reliability)
Cost = 1 (low cost)

• Cosa potrebbe succedere se alzo il RWIN?
• Se invece di usare il modem in accomodato ( IPM DATACOM USB ) uso unaltro modem? Migliorerebbe? o forse ethernet?
Grazie
