In fact, I did type [EMAIL PROTECTED]:~$ iwconfig lo no wireless extensions. eth0 no wireless extensions. eth1 unassociated ESSID:"" Mode:Managed Channel=0 Access Point: Not-Associated Bit Rate:0 kb/s Tx-Power=20 dBm Sensitivity=8/0 Retry limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Then I saw that the Kernel detected fine my Wireless, therfor I did try to connect to my Network, then I did type. [EMAIL PROTECTED]:~$ sudo iwconfig eth1 essid "blanco" It's don't send any error, I saw if did connect to the network with [EMAIL PROTECTED]:~$ iwconfig eth1 unassociated ESSID:"blanco" Mode:Managed Channel=0 Access Point: Not-Associated Bit Rate:0 kb/s Tx-Power=20 dBm Sensitivity=8/0 Retry limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 How the ESSID="blanco" then i did send a dhclient command, with: [EMAIL PROTECTED]:~$ sudo dhclient eth1 There is already a pid file /var/run/dhclient.pid with pid 6823 killed old client process, removed PID file Internet Systems Consortium DHCP Client V3.1.1 Copyright 2004-2008 Internet Systems Consortium.
