Probleme de Wifi

tk37 · Le 31/08/2008, à 14:26

Salut à tous j'ai un ordi portable HP 6715b donné par le Conseil General des BdR sous Ubuntu 7.10. Voila le probleme je n'arrive pas à me connecter avec la Wifi. Elle ne detecte rien.

La commande iwconfig donne ca :

alan@ubuntu:~$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

eth1      IEEE 802.11b/g  ESSID:off/any  Nickname:"Broadcom 4311"
          Mode:Managed  Frequency=2.427 GHz  Access Point: Invalid   
          Bit Rate=1 Mb/s   Tx-Power=18 dBm   
          RTS thr:off   Fragment thr:off
          Link Quality=0/100  Signal level=-256 dBm  Noise level=-256 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0
