Dall'output dmesg | grep usb si notano dei moduli che vengono ripetuti in diverse righe; suppongo che sia qualche bug di Ubuntu 12.04 o la tua chiavetta wifi ha bisogno di un driver aggiornato.

Da terminale postami questi comandi con la chiavetta wifi inserita:

Codice: Seleziona tutto

dmesg | grep rtl8192cu

grazie mille per l interessamento!

Prego, di nulla!

rtl8192cu: Tx queue select: 0x05

potrebbe essere un problema di driver!

Senza la chiavetta wireless, dai questi comandi:

Clicca col tasto destro sull'icona di NM, vai su Modifica connessioni...; seleziona la tua rete wireless e clicca su Modifica, vai su Impostazioni IPV6, mettilo da Automatico su Ignora e poi clicca in basso a destra su Salva; chiudi la finestra.

inserisci la chiavetta wireless e prova la connessione ad Internet, se dovesse disconnettersi un'altra volta, proviamo a scaricare e compilare il nuovo driver per la tua chiavetta.

Ciao.

[deris]

ho provato ma nulla, con ubuntu 11.04 non avevo problemi poi ho provato tutte le versioni fino al 13.10 e con tutte ho problemi

[magozurlinux]

Scarica il driver RTL8192CU da questo link, scorrendo la pagina:

http://www.realtek.com/downloads/downlo ... loads=true

lo troverai nella cartella Scaricati copialo o spostalo nella cartella Home.

Da terminale dai questi comandi:

Codice: Seleziona tutto

sudo apt-get install build-essential

Codice: Seleziona tutto

unzip RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911.zip

Codice: Seleziona tutto

cd RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911

Codice: Seleziona tutto

sudo -s

Codice: Seleziona tutto

./install.sh

[deris]

con l ultimo comando mi da accesso negato

[magozurlinux]

Da terminale dai questi comandi:

Codice: Seleziona tutto

cd RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911

Codice: Seleziona tutto

sudo chmod +x install.sh

Codice: Seleziona tutto

sudo -s

Codice: Seleziona tutto

./install.sh

[deris]

ho fatto la procedura ma niente, e se installo qualche altra versione? a me non fa differenza!

[magozurlinux]

Prova in quest'altro modo:

da terminale dai questo comando:

Codice: Seleziona tutto

echo blacklist rtl8192cu | sudo tee -a /etc/modprobe.d/blacklist.conf

riavvia il pc.

Riavviato Ubuntu, apri il terminale e dai questi comandi:

Codice: Seleziona tutto

cd RTL8188C_8192C_USB_linux_v4.0.2_9000.20130911

Codice: Seleziona tutto

make

se non ci sono errori di compilazione, dai questi comandi:

Codice: Seleziona tutto

sudo make install

Codice: Seleziona tutto

sudo modprobe 8192cu

vedi se così la rete wireless funziona.

[deris]

Dopo qualche giorno di prove il problema è scomparso!
Grazie mille!
ora se passo a una versione successiva potrebbe tornare il problema?

[magozurlinux]

Prego, di nulla!

Sì, se passi ad una versione successiva il problema potrebbe essere risolto ma si potrebbe anche ripresentare!

Ciao.
