Dernière chose avant de passer à [Résolu], la connection Wifi rétablie n'étant pas stable, je suis allée voir [doc]
https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx[/doc] et j'ai suivi le mode opératoire conseillé de désinstaller le paquet bcmwl-kernel-source et de réinstaller les pilotes B43 . Cette fois-ci, ça a marché, la connection wifi est stable, je l'utilise pour envoyer ce post et je remercie encore mille fois les intervenants qui m'ont aidée. 🙂
