Questi sono i valori della mia connessione:
SpeedGuide.net TCP/IP Analyzer
TCP properties for IP = 80.117.234.10 (host10-234.pool80117.interbusiness.it)
Browser/OS = Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)
Note: Read the FAQ if the above is not your IP address.

TCP options string = 020405b401010402

MTU = 1500
MTU is fully optimized for broadband.

MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Default Receive Window (RWIN) = 32000
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 32000
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

bandwidth * delay product:
Your RcvWindow limits you to: 1280 kbps (160 KBytes/s) @ 200ms
Your RcvWindow limits you to: 512 kbps (64 KBytes/s) @ 500ms

MTU Discovery (RFC1191) = ON

Time to live left = 121 hops
TTL value is ok.

Timestamps (RFC1323) = OFF

Selective Acknowledgements (RFC2018) = ON

IP type of service field (RFC1349)= 00000000


Sinceramente non è che ci siano dei problemi, tuttavia alcune volte non si vuole connettere (basta che riavvio il sistema e si connette). E mi sembra che il ping sia un po' alto.
