Bonjour à tous,
et bonne année, on espère qu'elle sera un peu plus sereine que la précédente !
Voici le topo (j'ai un peu fouillé mais je ne trouve pas de solution adéquate -- bon, il est aussi fort probable que je sois mauvais ^^) :
j'ai installé une clé wifi il y a quelques jours
en suivant les judicieux conseils de xubu1957.
Tout fonctionnait très bien.
Aujourd'hui : prise murale sauvagement débranchée pendant que l'ordi tournait, et depuis, plus de wifi.
J'ai donc tenté la même procédure, mais la dernière commande me renvoie
celinolive@R2D5:~$ sudo modprobe 88x2bu
[sudo] Mot de passe de celinolive :
modprobe: ERROR: could not insert '88x2bu': Exec format error
Bref, me revoici sans wifi, et je sollicite encore l'aide de cette estimable communauté !
Voici le retour du (nouveau) wificheck
