Ubuntu 18.04 - Disconnessione continua dongle Wifi
#1
Sad 
Buonasera a tutti,

da quando ho aggiornato il mio Ubuntu alla versione 18.04 non riesco a connettermi più di 10/15 minuti alla volta che il mio dongle wifi si disconnette. Per riconnettermi devo sganciare la chiavetta e riagganciarla tutte le volte.

questo è ciò che mi compare dal comando "lsusb":

Devo "piallare" il mio PC o posso correggere il problema senza fare piazza pulita??

Grazie a tutti per l'attenzione.

la chiavetta wifi è questa vero?
Codice:
Bus 001 Device 009: ID 0846:9030 NetGear, Inc. WNA1100 Wireless-N 150 [Atheros AR9271]
Con la chiavetta inserita ( e possibilmente nel periodo funzionante) prova a dare il comando:
Codice:
lshw -C network
per avere le specifiche della chiavetta ed i driver che utilizza.
controlla se per caso nei repository o sul sito del produttore ci sono driver specifici.
Può darsi che in fase di aggiornamento i driver originari siano stati sotituiti e/o non caricati/installati.
