Salve a tutti,
vi avviso che non sono molto pratico di ubuntu.

Ho disinstallato Windows XP e ho messo Ubuntu 14.04 in un Aspire 5315; con XP non avevo avuto nessun problema in Wifi, invece con Ubuntu la connessione è lenta e la ricezione segna due tacche; la cosa strana è che alcune volte ho notato che la navigazione è velocissima.

Ho provato a mettere i driver Windows ma la scheda non funziona più.

ciao @ninnik, Ubuntu 10.04 desktop non è più supportato, dovresti passare ad una versione più recente ancora supportata: Ubuntu 12.04 LTS (fino ad Aprile 2017) o Ubuntu 14.04 LTS (fino ad Aprile 2019).

Restando sulla 10.04 non riceverai alcun aggiornamento, nè per risolvere il tuo problema nè di sicurezza.

Il Wiki di Ubuntu-it ti sarà d'aiuto per tutto quello che riguarda l'installazione. Controlla anche di avere i requisiti sufficienti per Ubuntu, altrimenti puoi installare una derivata più leggera

sudo rmmod -f ath5k
sudo modprobe ath5k nohwcrypt=1
