Tu avais branché la TP-LINK TL-WN821N ?

Abyssecameleon7

quand j'ai fais les commandes non ... mais j'ai dejas une carte wifi sur mon ordinateur mais elle est un trop vieille

xubu1957

Il faut les retours de commandes avec l'adaptateur TP-LINK branché !

Il a détecté l’adaptateur :

Bus 001 Device 009: ID 0bda:8178 Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter

mais il donne priorité à la carte :

01:09.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller [10ec:8185] (rev 20)

Il faudrait débrancher la carte comme l'avait fait Hephaistos_9 , voir # 11 dans cette discussion : forum.ubuntu-fr.org/viewtopic.php?pid=21477691

Abyssecameleon7

euuhhh ok mais la débrancher physiquement ??

Abyssecameleon7

voila c'est fais une fois fait je retélécharge ??? ou pas besoin ?

xubu1957

Essaies de redémarrer !

Abyssecameleon7

sa ma refais la même erreur en lancé mon cd ...

xubu1957

Tu peux te brancher en filaire pour détecter les pilotes wifi ?

Abyssecameleon7

oui

Abyssecameleon7

il le detecte trés bien aprés c'est un vieille ordi je sais pas si sa peut marcher dessus

xubu1957

Lances la commande:

sudo apt-get update

et donnes le retour complet.

piotw2

surement un problème de dhcp
chez moi testé sur 2 vieux ordis et deux récents: ne parvient pas à créer l'adresse IP
je suis sur Mint 17.3 et il y a 6 mois cette clé wifi fonctionnait à merveille

piotw2

si ça peut servir:

chez moi j'ai résolu en rétrogradant le noyau de 3.19 à 3.16, pas testé en 3.18
