4 mega e wi-fi

[devik118]

ciao a tutti.

ho alice 1.2 e da circa 2 mesi ho la portante..(ne e' la prova il mio router) a 4.8 mega..ma rubinetti chiusi. Premetto che sono uno di quelli che aveva alice flat..e il passaggio mi deve essere fatto da loro senza una mia richiesta o cambio tariffa)
================================================== =============
MTU = 1400
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.
MSS = 1360
MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

Default Receive Window (RWIN) = 257040
RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
Unscaled Receive Window = 64260

RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
522240 (MSS x 48 * scale factor of 8)
261120 (MSS x 48 * scale factor of 4)
130560 (MSS x 48 * scale factor of 2)
65280 (MSS x 48)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 10281.6 kbps (1285.2 KBytes/s) @ 200ms
Your RcvWindow limits you to: 4112.64 kbps (514.08 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 55 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000 (0)

Questo e' quello che mi dice speedguide...
ho scaricato il programma che vete consigliato precedentemente e modificato secondo i vostri consigli...ma al riavvio non cambia nulla..
preciso che sono collegato via wi-fi al router adsl d-link.

consigli?
per la 4 mega che non arriva che faccio?

ciao

mtu va alzato a 1500 e risistemato il rwin ma se hai una scheda ricevente wi-fi della dlink, alcuni driver limitano mtu a quel valore

okok....ho settato alcuni parametri del modem..senza usare il programmino...questi i risultati:

TCP options string = 020405b40103030201010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.

Parere tecnico????

e per la 4 mega che non arriva che faccio?

1) Valori OK.
2) Aspettare aspettare aspettare.
