[Résolu] - carte wifi BCM43142 non reconnue

Bonjour à tous,
Heureux d'avoir récemment migré vers Ubuntu sur mon nouveau Thinkpad sans aucun souci, je voulais faire découvrir les joies de Linux à ma sœur sur son PC portable Dell. Malheureusement, tout ne se passe pas aussi bien que sur mon PC. En effet, la carte wifi n'est pas reconnue. Je vous joins ses caractéristiques :

02:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
ubuntu@ubuntu:~$ 

Merci à ceux qui prendront le temps de lire et de s'intéresser à mon problème.

Merci pour votre réactivité. J'espère avoir bien suivi les instructions :

To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

Re : [Résolu] - carte wifi BCM43142 non reconnue

1) Pour la carte wifi :

Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)

suite au bug  connu : bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1572659

En version 16.04, il suffit de désactiver le secure boot!

Voir notre documentation : desactiver_secure_boot

2) le noyau n'est pas le dernier sorti :

4.4.0-31-generic x86_64

il faudrait, branché en Ethernet , faire les mises à jour :

sudo apt update

sudo apt full-upgrade

suivi d'un redémarrage.

Finalement, on a réussi à régler le problème en réinstallant Ubuntu. La carte a été immédiatement reconnue. Etrange !
Encore merci
