Calo di potenza?

[AxW3b]

Ragazzi mi sembra che da quando ho spostato il computer da una stanza all'altra (e quindi anche relativo modem ethernet)la mia adsl si sia "indebbolita".

Potete dare un sguardo a questi valori per vedere se sono ok?
Cmq è una 640/128 di tin.it su protocollo PPPOE (nativo di windowsxp)

Grazie!

Se i collegamenti fisici sono a posto non credo che le prestazioni possano diminuire.

Se vuoi migliorare qualcosa puoi usare RASPPPoE
http://www.raspppoe.com/

e dopo la settiamo di conseguenza.

ok ho installato il raspppoe. riporto i test:

RWIN = 31944
Timestamp = OFF
Sia come fare?


Dopo puoi fare un test di velocità

No

[AxW3b]

Ho scaricato Dr.TCP, credo che vada bene,.. ho settato come mi hai consigliato te.. spero ke vada bene (vedi allegato)

[AxW3b]

Ok ho fatto i test con le modifiche apportate

17-gen-04 14.53.37 MISURE TERMINATE Prove :10 Velocita' Media :667.9579899805394Kbit/sec

credo che vada bene la mia adsl.... :tongue:

[pieba1]

Direi che va bene.

Per sicurezza puoi rifare il test di Speedguide per vedere se ti ha preso i settaggi.

eccoli qui. grazie ancora cmq..
