(résolu) Probleme de connexion wifi avec un PC portable MSI
J'ai un PC portable MSI GS60 2PC-247XFR Ghost sur lequel je viens d'installer avec succès Ubuntu 14.04 TLS 64bits...
J'ai un p'tit probleme par contre avec la connexion wifi : il a du mal à capter les réseaux environnants (en particulier la neuf-box qui m'intéresse) alors que celui de ma chérie bien moins performant mais sous windows 8 capte parfaitement à coté du mien, c'est un peu vexant lol !
Merci pour vos lumières et passez de bonnes fêtes !!!
Voici les caractéristiques wifi annoncés par MSI :
Norme(s) réseau sans-fil : Wi-Fi AC, Wi-Fi B (IEEE 802.11b), Wi-Fi G (IEEE 802.11g), Wi-Fi N 150 Mbps (IEEE 802.11n)
Norme(s) réseau : 10/100/1000 Mbps Controleur réseau intégré...

Re : (résolu) Probleme de connexion wifi avec un PC portable MSI
salut
essaye cette cmd :
echo "options iwlwifi bt_coex_active=N swcrypto=1 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.confreboot et test si c'est mieux
Tombé dans l'informatique étant petit, j'en ai fait mon métier. Utilisateur d'Ubuntu depuis novembre 2006, actuellement sous 20.04 x64 (Que d'évolution
depuis Dapper Drake ! Ça rajeunit pas ^^^).
