I'm connecting to my machine via ssh. Trying to connect it my to my AP. The problem is that the wi fi is active but not connected to my AP.
It is Running Debian GNU/Linux 6.0
When I run the command iwconfig mlan0 essid MY_SSID
I get the following error.
Error for wireless request "Set ESSID" (8B1A) :
SET failed on device mlan0 ; Bad address.
And checking in the log, it says:
kernel: Can not find ssid MY_SSID
I've already edited the /etc/network/interfaces
file adding:
auto mlan0
iface mlan0 inet dhcp
What I did after that was trying to conect with a wpa_supplicand.conf file with this line:
/usr/bin/wpa_passphrase MY_SSID MY_Secret_Wifi_Password | tee -a /etc/wpa_supplicant.conf
And I've created a wpa_supplicant.conf
file containing:
network={
ssid="MY_SSID"
#psk=MY_PASS
psk=MY_CIPHERD_PASS17ce47de00e8ec55983b111a79ffefdabbe5a2ca645459
}
I test if this Works With the line:
wpa_supplicant -imlan0 -c/etc/wpa_supplicant.conf -d
But i get errors saying that an AP cannot be found.
I turned my interface up with:
linux:~# /sbin/wpa_supplicant wpa_supplicant -d wext -i mlan0 -c /etc/wpa_supplicant.conf -B
so the ifup mlan0 says that it is already up.
If I run the iwlist scanning
command i can see my AP.
mlan0 Scan completed :

Right now I'm connected to it via Ethernet And trying to keep the wifi connection only. Another thing is that the lspci
command doesn't return a thing.
If another file is needed, ask me to upload it. I want to establish the wireless connection.
Thank you
I would recommend on enabling
squeeze-backports
so you use a not too old kernel version. On linux 3.2iwconfig
andiwlist
are deprecated. useiw dev wlan0 scan
andiw dev wlan0 connect
. Also, the output ofreadlink /sys/class/net/mlan0/device/driver
would be nice. – BatchyX – 2013-01-20T18:44:04.433@BatchyX It doesn't recognice the
iw
commands by default, right? .. I'll check the squeeze-backports ... and with thereadlink
command I get../../../../../../../bus/sdio/drivers/wlan_sdio
.. what does that mean? .. – AAlvz – 2013-01-20T19:36:59.880iw
is fairly recent and it's not surprising for it to not be available by default on OS that still ship Linux 2.6.38. As for the readlink command, it means your wlan driver is calledwlan_sdio
