Ubuntu 18.04 e WiFi non funzionante

[paologaffu]

Buongiorno a tutti.

Fino a ieri andava tutto bene. Da stamattina il mio PC non con Ubuntu 18.04 non trova più la WiFi nel senso che non riconosce la presenza di un hardware wifi a bordo del PC (schermata con il punto di domanda ed il messaggio nessun adattatore wifi trovato.

Ho provato questo comando

lspci -nn | grep -i net

mi ha restituito questo

Qualcuno gentile che possa aiutare?

dall'output che hai postato la scheda di rete WIFI è stata rilevata. Posta anche questi output

Attiva il wifi tramite l'apposito pulsante hardware o con FN+ F8 se non funziona prova Fn+ F4-F12

[paologaffu]

Attivando con apposito pulsante non accade nulla

Fn F8, agisco sul volume.

Fn F4 F12 compare un simbolo di divieto

Ho anche provato il riavvio del PC ma nulla

[thece]

Attiva il wifi tramite l'apposito pulsante hardware ...

Magari prima di attivare la scheda di rete WIFI installiamo anche il suo driver, che ne dici?

Eppure fino a ieri funzionava tutto. Come installare i driver?

fai pure ma se fino a ieri sera funzionava, sono andati in ferie questa notte ?
Mentre che il wifi sia bloccato via hardware è certo.

Ho modificato il mio post sopra

fai pure ma se fino a ieri sera funzionava, sono andati in ferie questa notte ?

E' Agosto, non lo escluderei.
