WIfi no wireless extensions

randy45

Bonjour,

je suis nouveau sur linux (ubuntu 16.04 lts) et j'ai une question concernant ma configuration... tout marche nikel (je peux me connecter à mon réseau) mais lorsque je fais la cmd iwconfig j'ai la mention "no wireless extensions" et j'aimerais savoir à quoi cela correspond.
Merci de bien vouloir éclairer ma lanterne 🙂

Modération : merci à l'avenir d'utiliser les balises code (explications ici).

Salut !

simple, via man iwconfig, on voit entre autre :

NOM
       iwconfig - configure une interface réseau sans-fil

iwconfig gère les interfaces sans fil.

et enp4s0f2 est une interface Ethernet
l'outil liste cette interface mais indique que ce n'est pas une inter sans file.

et lo est une sorte d'interface virtuelle.

essaie avec

ifconfig

, tu verras toutes les IR sans distinction de type.

c'est un comportement normal.
