Ciao a tutti
da qualche giorno, da quando ho cambiato il modem router, il mio portatile
hp pavilion dv9585 si disconnette ogni tanto dalla rete wifi.
il modem nuovo è un alice gate2 (modello AGA), al quale ho sostituito il
firmware originale (definito da autorevoli commentatori "Cesso da corsa")
con quello dello USR9108A.
il canale scelto è stato 11 e ora 8. L'interfaccia di configurazione del
router mostra 13 canali disponibili.
il modulo wifi caricato è iwl3945.
la rete usa crittografia WPA.
il sistema (ubuntu 9.10) usa network-manager. Nota bene: dopo la
disconnessione non si riconnette più automaticamente: se vado a vedere nelle
connessioni configurate in nm non c'è più la password!!!
nel log di seguito la connessione wifi si chiama "Casa senza fili"
l'altro pc che ha installato Uindos IcsPì pare non soffrire di questo
problema-
se avete voglia di consigliarmi, ecco syslog
ciao, grazie!
marco
