[Risolto] [Wireless] Problema connessione Wi-Fi

[Ciccio14]

Come da titolo ho un problema con la connessione Wi-Fi del mio Notebook Acer TravelMate 2490...
Quando ho installato Ubuntu 10.04 avevo già riscontrato il problema, e cioè che Network Manager non trovava la rete Wi-Fi del mio modem di casa (come se fosse completamente inesistente)... Allora ho seguito delle guide e ho installato Wicd e disabilitato Network Manager... Ma non ho risolto il problema... Anche stavolta non trova la rete Wi-Fi e mi dice: "Nessuna rete wireless trovata".
Come posso risolvere il problema?
Grazie in anticipo.

P.S. Premetto che con Windows 7 va tutto alla perfezione, quindi presumo che non sia un problema del PC.

Da terminale, digita

sudo lshw

E posta il risultato che vediamo se Ubuntu ha riconosciuto almeno la presenza della scheda.

Scusa la mia ignoranza ma non sono molto pratico del Linux... come faccio a copiare il risultato del terminale???

Ci sono riuscito! =)

Ora posto tutto il risultato

Questo è tutto il risultato...

Ok, il sistema sa che hai una scheda Broadcom...

Connetti il cavo LAN, Sistema - Amministrazione - Driver Hardware

Dovrebbe andare a scaricarti in automatico i drivers... Una volta scaricati e attivati i drivers, togli il cavo LAN e poi il WIFi dovrebbe funzionare (devi solo settarlo).

[Ciccio14]

Ok stasera provo questo sistema, non lo faccio adesso perchè non sono a casa...
Comunque se provo ad andare su Drivers Hardware senza connessione mi da un errore, è normale?

[Nicola Riva]

Si, perché va a cercare on-line eventuali drivers di hardware nuovo...

[Ciccio14]

Ok grazie mille ti farò sapere se riesco a risolvere...
Un ultima domanda: posso continuare ad usare Wicd o no?

[Nicola Riva]

Con Network Manager ha funzionato tutto al primo colpo (c'è anche un'ottima guida: http://wiki.ubuntu-it.org/Hardware/Disp ... /GuidaWiFi), e anch'io ho una scheda Broadcom...

Vedi tu, se risolvi così, va bene lo stesso... Se non riesci prova a reinstallare Network Manager.

[Ciccio14]

Ok grazie ancora per la disponibilità... stasera ti farò sapere.

[Ciccio14]

Finalmente ho risolto il problema grazie ai tuoi consigli... grazie

Adesso però è sorto un altro problema...Mi sono connesso regolarmente alla rete wi-fi, ma quando apro Mozzilla, o Google Chrome mi dice che non c'è connessione. In sostanza il problema è questo: mi sono connesso alla rete wi-fi ma non naviga in Internet.

[Nicola Riva]

Forse è simile a quello che mi è capitato qualche sera fa...

Ho operato tranquillamente con Internet. Poi ho spento e quando ho riacceso il PC non andava più Mozilla eppure la rete wifi era connessa.

Mi sono disperato, ma poi ho guardato il modem (ho un vecchio modem a cui ho attaccato un router wifi): non c'era più connessione DSL...

Quindi ho spento il modem e l'ho riavviato. Magicamente è tornato a funzionare. Prova così...

[Ciccio14]

Niente da fare, non va lo stesso...

[Nicola Riva]

Che router/modem hai?

[Ciccio14]

Alice gate VoIp 2 Plus Wi-Fi

[Nicola Riva]

Ah ecco...

Guarda caso quel router dà parecchi problemi e ci hanno fatto una guida apposta...

Segui le istruzioni al link seguente:

http://wiki.ubuntu-it.org/Hardware/Mode ... e2PlusWiFi

[Ciccio14]

Ok, adesso ci provo e ti do aggiornamenti... Grazie ancora dell' aiuto.

[Ciccio14]

Non lo posso fare... perchè nella guida dice: Scegliere Sistema -> Amministrazione -> Rete.
Ma su Amministrazione non c'è la voce "Rete"...
Sto cominciando a stufarmi.

[Nicola Riva]

Giusto, è perché fa riferimento alla versione 9.04 di Ubuntu...

Dovrebbe essere il Network Manager... Adesso sono in ufficio, stasera arrivo a casa e ti posto il corrispondente...

[Ciccio14]

Grazie ancora una volta per la tua gentilezza e disponibilità...
Allora aspetto...
