Settaggi ADSL

[gandalf_2183]

Mi hanno attivato oggi libero adsl flat.
Ho seguito la guida di Fivendra e ho impostato i valori con DrTcp.
Io ho un modem USB, Win XP e la linea è ancora 640/256.
Potete però dagli una controllatina x sicurezza? Grazie mille

TCP options string = 020405a00103030001010402
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) = 31680
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 31680

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 (Note this is not a speed test):

Your RcvWindow limits you to: 1267.2 kbps (158.4 KBytes/s) @ 200ms
Your RcvWindow limits you to: 506.88 kbps (63.36 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 57 hops

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

va bene così. dovresti portare MTu a 1500 ma con win xp e modem usb non è sempre possibile.

Infatti io l'avevo impostato a 1500, ma una volta riavviato e riprovato il test mi dava ancora il valora vecchio

[Rockmaker]

e purtroppo dipende da win xp.
io mi sono comprato un modem ethernet in cui il MTU lo setti dalla configurazione del modem stesso. si puòa nche sui router

Prova ad usare tcp optimizer forse ti migliora qualcosa ma non ne sono sicuro lo trovi qui :http://www.speedguide.net/downloads.php

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) = 31944
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 31944

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)

Your RcvWindow limits you to: 1277.76 kbps (159.72 KBytes/s) @ 200ms
Your RcvWindow limits you to: 511.104 kbps (63.888 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 119 hops

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

ragazzi questi sono i miei valori ma come cavolo si cambia il mss*44 in mss*22?

grazie in anticipo

[Rockmaker]

non devi cambiare mss*44 (non sono valori tcp quelli) scarichi questo http://www.dslreports.com/front/DRTCP021.exe e nella casellina rwin metti mss*22 cioè 1460*22=32120. salvi riavvii e ripeti il test

[Alejandro82]

ah ok than you

[Alejandro82]

ora? tutto ok?

perfetto, guarda ancora se riesci a portare il TTL a 64.
dopo prova un bel download
