[Risolto] Qualcomm Atheros AR9285

[eduardolp3]

Salve a tutti,
ho appena installato Ubuntu Mate su un Acer (della mia compagna, non so quale modello specifico e neanche come trovarlo, come faccio?) e la scheda wifi in questione non funziona (in Driver aggiuntivi neanche l'ombra). Quando ho iniziato a installare il sistema l'ha vista e ho provato a collegarmi ma non sono riuscito, poi, una volta riavviato non la vede proprio.
Qualche consiglio?

Da terminale postami questi comandi:

Grazie per le risposte e scusate il ritardo.
Fatto sta che che dopo aver iniziato questa discussione ho spento il computer e ho lasciato stare il problema. Siccome mia compagna non si è lamentata della mancanza di collegamento wifi ho avviato il pc e per magia il wifi è funzionante. Io comunque ho dato i comandi, tranne l'ultimo che ho visto un "kill" e con paura di killare il wifi e restare senza internet ho preferito lasciare così com'è.
Devo dire però che ho visto in rete che Atheros non è un gran chè e mi sono ricordato che quando girava Windows mia compagna si lamentava spesso che la connessione era instabile. Quindi se si può migliorare con qualche aggiornamento del driver o qualcosa del genere, e se non vi scoccia vorrei proseguire con la ricerca, se possibile, di una ottimizzazione del wifi. Se devo dare l'ultimo comando, ovvero

rfkill list

fammi sapere.
Per ora non posso fare altro che ringraziare!

Non trovo SYSTEM INFORMATION!!!!

[trekfan1]

Come no?

Codice: Seleziona tutto

System Information
   Manufacturer: Acer
   Product Name: TravelMate 5744Z
   Version: V1.07
   Serial Number: LXV5N0C00912603B476500
   UUID: 8BEA0E80-05C9-8148-2969-E06995EAB33B
   Wake-up Type: Power Switch
   SKU Number: Calpella_CRB
   Family: Intel_Mobile

Se era instabile anche sotto windows direi che è un problema hardware della scheda wifi, a questo punto io consiglierei di sostituirla, per pochi euro si trovano su ebay/amazon.

PS: per favore evita di fare post doppi consecutivi ma clicca su Modifica e aggiungi il nuovo testo (questo per il futuro ovviamente)

Per trefkan1: non trovo SYSTEM INFORMATION, devo dare un comando nel terminale oppure è nascosto in qualche menu? Non lo trovo, scusate il post doppio.

Se leggi l'output lo trovi, cmq lo ho postato io facendo copia/incolla dal tuo output

Salve, scusate il ritardo ma ero via.
Ho seguito le tue indicazioni e anche dato il comando che hai detto, sto provando la connessione e per ora va tutto bene. Metto risolto e se avverto qualche problema mi faccio sentire.
Per ora grazie e buone ferie a tutti!

[magozurlinux]

Prego, di nulla!

Perfetto!
