ciao a tutti, sono in lan, e sia che da windows e linux
non riesco mai a superara 30kb/s stabili
ecco il risultato del test per vedere i valori (questo è fatto da windows xp, dato che linux è solo gateway e tiene la connessione)

TCP options string = 0204058401010402
MTU = 1452
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1412
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 17280
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 17280

For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
519616 (MSS x 46 * scale factor of 8)
259808 (MSS x 46 * scale factor of 4)
129904 (MSS x 46 * scale factor of 2)
64952 (MSS x 46)
bandwidth * delay product:

Your RcvWindow limits you to: 691.2 kbps (86.4 KBytes/s) @ 200ms
Your RcvWindow limits you to: 276.48 kbps (34.56 KBytes/s) @ 500ms
Consider increasing your RWIN value to optimize TCP/IP for broadband.
MTU Discovery (RFC1191) = ON
Time to live left = 55 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000
P.S. ho alice 256

ciao e grazie
