perdità del segnale tra Alice W-Gate e Intel Pro Wireless 3945ABG

[epris]

Ciao a tutti,

io ho come router wifi Alice W-Gate.
Come portatile: Toshiba P100-407 che installa come scheda di rete INTEL PRO/WIRELESS 3945ABG

Ho grandissime difficoltà con la connessione WiFi. In pratica individua quasi sempre la rete (90%) ma in tutto si sarà connesso 6 volte, di cui: 2 sono riuscito a connettermi ad internet, le altre 4 è caduto la connessione dopo pochi secondi (qualità del segnale passa da ottimo ad insufficiente).
Le due volte che sono riuscito a collegarmi ad internet la connessione è durata per circa 20 mint , dopo si è disconnesso da solo senza più connettersi.

Tramite il programma della Intel che ricerca le reti wireless ho questo listato sulla comunicazione tra il ricevitore e il trasmettitore wifi. Qualcuno, leggendolo, capisce la fonte dei mie problemi?

Dimenticato: come protezione uso WPA

sostanzialmente, se notate, a volte l'autenticazione va altre no. E il segnale viene perso. Voi ci capite qualcosa?
(il listato si legge dal basso, il primo messaggio è il 547)
