pb activation wifi en 32 bits
Bonjour
Sur 2 machines distinctes, en Ubuntu 16.04, et qui ont le point commun d'être un peu âgées (5 à 7 ans) et avec un processeur 32 bits (i386).
Une fois sur deux au moins, parfois plus, après démarrage à froid ou redémarrage à chaud, le périphérique WiFi n'est pas prêt.
Je ne rencontre jamais ce problème sur les machines plus récentes 64 bits, et surtout je ne l'ai jamais rencontré sur les machines incriminées quand elles avaient 14.04
Est-ce que ce problème est connu et peut se régler ?
Merci pour vos suggestions.

Re : pb activation wifi en 32 bits
Salut,
Comme indiqué dans ce sujet, essaye de créer le fichier avec :
echo "options ath9k nohwcrypt=1" | sudo tee -a /etc/modprobe.d/ath9k.confAprès redémarrage, cela devrait aller mieux.
A+
Un problème résolu ? Indiquez le en modifiant le titre du sujet.

Re : pb activation wifi en 32 bits
Bonjour
Cela ne change rien, il faut toujours plusieurs démarrages pour que le wifi soit actif.
$ cat /etc/modprobe.d/ath9k.conf
options ath9k nohwcrypt=1Faut-il conserver le fichier créé ?
J'essaie
echo ath9k | sudo tee -a /etc/moduleset je vous tiens au courant.
Mais ce ne me semble pas les mêmes symptômes que dans le message cité car au démarrage le réseau et le wifi sont inactifs tous les deux, et on ne voit évidemment aucun point d'accès wifi.
