wi fi non rilevato su 14.04

[anita]

Ciao, premetto che ho già letto varie discussioni ma non ne vengo a capo. Sto utilizzando ubuntu 14.04 su un acer aspire e15 e non vuole saperne di rilevarmi il wi fi. La scheda wireless è Qualcomm Atheros. Ho anche provato a installare i backports ma niente... Nel gestore di rete mi dà solo la connessione via cavo, non c'è neanche l'opzione "abilita wi fi". Cosa posso fare?

[ubuz]

ciao, hai ubuntu "puro" o qualche derivata?
il gestore reti è network-manager?

[pachisapiu]

la prima cosa è capire che scheda wifi ha quel pc , quindi posta

Non so cosa si intenda per ubuntu "puro" ma credo sia così... L'ho appena installato ex novo sul portatile. Il gestore reti è network-manager.

[ubuz]

prova a vedere se con questo risolvi.

per "puro" intendo non una derivata (Lubuntu, Kubuntu, Xubuntu, ecc)

posta anche il risultato di

non riconosce proprio la scheda.
prova a vedere se ti può essere d'aiuto:
https://digitz.org/blog/wifi-issue-on-a ... vice-0042/

una domanda: se hai installato ex-novo, perché la 14.04 e non la 16.04?

[anita]

Avevo già provato quella procedura, ma non è servita... Ho installato ubuntu 14.04 perchè mi ci trovo meglio... Nella 16 non mi piace il nuovo software center, continua ad incantarsi, e ho notato che alcuni programmi sono instabili, inoltre non riesco ad installare dei giochi vecchi che mi piacevano... Comunque a questo punto prenderò in considerazione l'upgrade della distro... Grazie!!

Buona serata.

Ciao, avevo già provato con i backports ma non aveva funzionato... Era per quello che avevo aperto una nuova discussione... In ogni caso ho optato per l'avanzamento di distribuzione. Ora con ubuntu 16.04 funziona... Grazie a tutti comunque!!
