collegamento wi-fi possibile da android ma non da ubuntu

[Pete]

Ciao

ho il seguente problema molto fastidioso.

Riesco a collegarmi ad una rete tramite collegamento wireless con il cellulare (android), senza alcun problema. Il dispositivo non mi chiede alcun setting particolare, se non la password di rete.

Quando provo a collegarmi con il mio pc (ubuntu 14.04, 64 bit, asus x52j), il tentativo di connessione fallisce. Al momento utilizzo il tethering con il cellulare, che tuttavia è un po' fastidioso!

Purtroppo non so dare altre indicazione, potreste darmi qualche idea sul motivo di ciò?

Grazie, ciao

Da software e aggiornamenti - Driver aggiuntivi controlla se ci sono driver da installare.

[Pete]

Grazie per la risposta, onestamente brancolo nel buio

In allegato la schermata

Dimenticavo: se ti riferivi al driver della scheda wi-fi probabilmente ti interessa sapere che mi sono collegato senza problemi alla rete dell'ufficio con il laptop

[VitoDoc]

Prova così, apri il l'editor di testo gedit e modifica il file rc.local in questo modo

Codice: Seleziona tutto

sudo gedit /etc/rc.local

prima del comando

Codice: Seleziona tutto

    exit 0

inserisci

Codice: Seleziona tutto

    iwconfig wlan0 rate 5.5M

salva e riavvia.

Provato, ma niente da fare...

Grazie per il tentativo


Ciao

Intanto sarebbe bello avere qualche informazione in più per l'identificazione sia della scheda di rete wireless, sia del problema. Quindi: scollega qualsiasi altro tipo di connessione, apri il terminale e dai questi comandi

Codice: Seleziona tutto

sudo lshw -c network

Codice: Seleziona tutto

lspci -knn | grep -A 2 -i net

Codice: Seleziona tutto

lsusb

Codice: Seleziona tutto

cat /etc/network/interfaces

Codice: Seleziona tutto

cat /etc/resolv.conf

Codice: Seleziona tutto

ifconfig -a

Poi prova a collegarti alla tua rete wireless e dopo qualche secondo che ci hai provato dai questo comando

Codice: Seleziona tutto

cat /var/log/syslog | grep -i networkmanager | tail -n 50

Come ulteriore test, temporaneamente prova a disattivare l'autenticazione WEP/WPA sul tuo router/access point, poi prova a ricollegarti e vedere se così funziona

[Pete]

Ciao

grazie, provo stasera quando torno a casa!

Posta anche l'output di questi comandi, che prima mi sono dimenticato:

rfkill list all

Codice: Seleziona tutto

sudo iwlist wlan0 scan

[Pete]

Eccoli!

Codice: Seleziona tutto

2: phy0: Wireless LAN

	Hard blocked: no


$ sudo iwlist wlan0 scan

wlan0     Interface doesn't support scanning : Network is down

Li ho eseguiti sia disconnesso da qualunque cosa, sia in tethering con il cellulare, stessi risultati

[thece]

Il tethering per ora lo puoi lasciare anche attivo. Hai la scheda di rete wireless disattivata via software. Dai

Codice: Seleziona tutto

rfkill unblock all

Poi di nuovo, per vedere se la scheda di rete si e riattivata

Codice: Seleziona tutto

rfkill list all

Codice: Seleziona tutto

sudo iwlist wlan0 scan

[Pete]

Ohhh scusa sono distratto, l'avevo disattivata io dopo aver collegato il tethering....

Allora l'output è

Codice: Seleziona tutto

$ rfkill list all

Ok, prova il test "temporaneo" e fammi sapere

[Pete]

OK....anche se sarà un po' più difficile dei test via terminale...

Ti dico la storia intera, magari è rilevante (anche se non penso). Sono in fitto in un appartamento all estero, e l'abbonamento non è a mio nome (me l ha lasciato chi era prima di me). Sto cercando da stamattina (quando mi hai scritto qui nel forum) come accedere alla pagina del modem, ma non trovo nulla in rete! Il gestore si chiama Free, è francese e ... fa schifo!!

P.S. Con il netbook Windows 7 non ho avuto problemi

Arrivato alla quarta pagina fra i risultati di google ho trovato questo suggerimento

Codice: Seleziona tutto

sudo echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf

Approfitto della tua pazienza per chiederti cosa fa prima di eseguirlo

Nello stesso post si consiglia anche di eseguire

Codice: Seleziona tutto

sudo rmmod ath9k
sudo modprobe ath9k

No

Sto cercando da stamattina (quando mi hai scritto qui nel forum) come accedere alla pagina del modem, ma non trovo nulla in rete! Il gestore si chiama Free, è francese e ... fa schifo!!

Intando dovrei sapere marca e modello del modem

La pagina Web di configurazione del modem solitamente la si può raggiungere solo quando si è connessi ad esso via cavo Ethernet (per questioni di sicurezza) e solitamente è raggiungibile ad un indirizzo del tipo http://192.168.0.1

[ EDIT ]

Poi occorrerebbe sapere la password ... certo si potrebbe resettare il modem, quindi riportare la sua configurazione allo stato originale, "di fabbrica", quindi accedere con la password di default, riconfigurarlo ... ma nella tua situazione è "rischioso", meglio non toccarlo
