Ragazzi ho bisogno di un grosso favore da voi ... io ho acquistato questo router e leggendo in giro ho visto dire che settando valori di MTU e RWIN in modo corretto si velocizza la connessione ...
Ho Alice 4 MB Utilizzando questo test http://forums.speedguide.net:8117/ ho trovato questi valori ...
TCP options string = 0204059e0103030201010402
MTU = 1478
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1438
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.
Default Receive Window (RWIN) = 83404
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 20851
RWIN is not fully optimized (even though it is a comparatively large number). The unscaled RWIN value is lower than it should be. Also, RWIN being close to and above 65535 does not justify the header overhead of enabling TCP Options. You might want to use one of the recommended RWIN values below.
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
506176 (MSS x 44 * scale factor of 8)
253088 (MSS x 44 * scale factor of 4)
126544 (MSS x 44 * scale factor of 2)
63272 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):
Your RcvWindow limits you to: 3336.16 kbps (417.02 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1334.464 kbps (166.808 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 54 hops
TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)
Noto che sono valori sballati da quelli consigliati per una ADSL 4mb in quanto MTU Dovrebbe stare sui 1492 e MSS 1452 e RWIN circa 256124
Ho provato a cambiare questi valori con diverse strade (DRTCP,TCP OPTIMIZER,da REGEDIT, direttamente Dalla pagina di configurazione del mio Router che mi da come valore MTU 1492.... ma quando rifaccio il test i valori sono sempre quelli indicati nel copia incolla qua sopra ... ) ho bisogno di una mano mi affido a voi :\
Ciao aspetto risposte !!!!! :mc:
