Wifi funziona solo per pochi minuti

[cuppls]

Salve,
ho ubuntu 14.04 lts su lenovo thinkpad e 555 20DH000TIX; il mio problema è questo, appena avvio ubuntu funziona tutto alla perfezione, dopo una decina di minuti che utilizzo internet , esso smette di funzionare,il pc mi dice che è collegato al wifi, ma internet non carica le pagine, o meglio le carica all'infinito senza aprirle.
Se provo a disconnettere il wifi e poi riconnetterlo non me la fare,non mi fa riconnettere.
Cosa devo fare?

Clicca in alto a dx sull'icona di NM, vai in basso su Modifica connessioni...; clicca su Senza fili, seleziona la tua rete wireless, clicca su Modifica, vai su Impostazioni IPv6, mettilo su Ignora e clicca in basso a dx su Salva.

Il problema c'è ancora..uff..

[gianliuc]

Allora ... se secondo me è il firmaware cè un difetto su ub.14.04 se vuoi vedere il kernel che stai usando e sarà immagino il 3.13 dgt

Codice: Seleziona tutto

sudo uname -a

e allora prova così....

Codice: Seleziona tutto

sudo apt-get install aptitude

e poi

Codice: Seleziona tutto

aptitude search linux-image

e vedi i kernel disponibili se hai un sistema a 64bit il tuo kernel sarà con architettura "amd64"

per installare

Codice: Seleziona tutto

sudo aptitude install linux-image <kernel scelto>

e riavvia

[cuppls]

Adesso non funziona proprio più il wifi! come faccio a togliere queste modifiche?

[gianliuc]

Adesso non funziona proprio più il wifi! come faccio a togliere queste modifiche?

se vuoi togliere

Codice: Seleziona tutto

sudo apt-get purge aptitude

ma è un gestore file perciò non compromette il sistema


prova a reinstallare il network manager

Codice: Seleziona tutto

sudo apt-get install -d --reinstall network-manager network-manager-gnome

Poi per eliminare esso -

Codice: Seleziona tutto

sudo apt-get purge network-manager-gnome network-manager

Per reinstallarlo (suggerisco un riavvio in-tra) dai pacchetti scaricati,

Codice: Seleziona tutto

sudo apt-get install network-manager-gnome

niente, adesso ho disinstallato ubuntu, vorrei provare a reinstallarlo e magari provare ad installare la nuova versione.
Ma ho un problema, quando devo scegliere dalla finestra di unebootin se installare ubuntu, provare ubuntu senza installare ecc, appena premo invio sulla scelta, vedo in basso a sinistra questo simbolo _ che lampeggia, e non succede assolutamente più niente, non mi fa nemmeno spostare la scelta, devo riavviare il pc;
diciamo che una volta su 20 mi fa scegliere..sono quasi disperato.. ma sapete perchè non va la chat di supporto di ubuntu?

[gianliuc]
