Da live cd il wifi ubuntu funziona senza problemi, appena ubuntu è stato installato il wifi lavora senza problemi.
Fino a qui tutto bene, quando mi escono gli aggiornamenti software da fare (297 aggiornamenti) li faccio e il wifi funziona ancora, appena mi chiede di riavviare per rendere effettive gli aggiornamenti il wifi non funziona più. Per farlo rifunzionare ho dovuto rieffettuare l'installazione di ubuntu da capo.
Volevo chiedere se eseguendo questi comandi riusciamo ad analizzare il sistema prima e dopo gli aggiornamenti per capire la causa di questo fastidiossisimo problema!
Questi sono i comandi da terminali che mi ha consigliato in chat per analizzare il sistema prima dell'aggiornamento:
