Un saluto a tutta la lista,
dopo essere riuscito far partire Debian in dual boot sul notebook (Acer
Aspire E5-574G), per l'installazione ho usato una weekly build di
testing datata 28/03/2016, ho iniziato a "lavorare di fino", partendo
dal wifi che "naturalmente" non funziona.
In fase di installazione mi è apparso il messaggio che richiedeva i
driver per la scheda Qualcomm Atheros QCA9377, ma ad installazione
terminata trovo:

In [1] si dice che per kernel 4.4-rc2 va applicata una patch al kernel, ma
uname -a
Linux Debian-E5 4.4.0-1-amd64 #1 SMP Debian 4.4.6-1 (2016-03-17) x86_64
GNU/Linux
per cui penso che non debba applicare la patch (o sbaglio??).
Come posso "vedere" l'interfaccia di rete wifi??
Grazie per il supporto.
