non lo so perche' quello che ha win 98 non lo uso molto!
provero' , cmq il raspppoe di 98 ci mette una vita nell'autenticazione, a differenza di xp che la fa' in mezzo secondo!

riguardo xp come ti sembra configurato? da quel poco che ne capisco mi pare ok, confermi? grazie

TCP options string = 020405a001010402
MTU = 1480
MTU is optimized for Windows XP PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.
MSS = 1440
MSS is optimized for Windows XP PPPoE DSL broadband. If not, consider raising MTU to 1500 for maximum throughput.

Default Receive Window (RWIN) = 64800
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 64800

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
506880 (MSS x 44 * scale factor of 8)
253440 (MSS x 44 * scale factor of 4)
126720 (MSS x 44 * scale factor of 2)
63360 (MSS x 44)
bandwidth * delay product:

Your RcvWindow limits you to: 2592 kbps (324 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1036.8 kbps (129.6 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
