un consiglio

[daddyser]

ho formattato dopo il famoso worm blaster,perke il pc mi dava problemi,ed ho voluto installare il rasPPPoE.uso Win xp,modem ethernet alice 640.ho fatto il test e mi esce questa situazione.mi date un consiglio come settare la mia Alicina?
SpeedGuide.net TCP/IP Analyzer


TCP properties for IP = 80.182.76.142 ()
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
Notes: Read the Analyzer FAQ if the above is not your IP address.

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

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: 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 = 118 hops

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

ho già scarikato il DRTCP021,e attendo Vs. notizie per settarla al meglio.grazie

Sei sicuro di aver installato RASPPPoE?

Te lo domando perchè anch'io ho XP + RASPPPoE e mi ha settato in automatico MTU=1492.

[daddyser]

si perke sto usando la nuova connessione creata dal raspppoe,e ho eliminato la connessione fatta con xp

[pieba1]

MTU = 1492
e di conseguenza
RWIN = 17424

[daddyser]

ecco qui il risultato:
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.

penso ke vada bene.Fatemi sapere

è sbagliato il valore di rwin perchè avendo una 640 devi mettere un valore corrispondente a mss per 22 e non per 12
quello è un valore cheva bene per una 256
