Unable to open connection to supplicant on "wlan0": No such file or directory

[Elvis Dowson]

Hi,
I am getting the following error, while trying to port my
Ralink RT2571WF wifi module to android-2.6.29.

E/WifiHW ( 918): Unable to open connection to supplicant on "wlan0":
No such file or directory
I/WifiHW ( 918): wifi_connect_to_supplicant called

How can I resolve this?

Some people who have enable wifi have set ctrl_interface to wlan0 in
their wpa_supplicant.conf file:

ctrl_interface=wlan0

Other have specified a directory:

ctrl_interface=DIR=/data/system/wpa_supplicant/ GROUP=system

This also gives me an error :-)

E/WifiHW ( 912): Unable to open connection to supplicant on "/data/
system/wpa_supplicant/wlan0": No such file or directory
I/WifiHW ( 912): wifi_connect_to_supplicant called

So, I'm not sure what I should be doing!! :-)

This is what my init.rc file looks like at the moment:

# create wifi filesystem structure
mkdir /data/misc/wifi 0770 system system
mkdir /data/misc/wifi/sockets 0770 system system
mkdir /data/system/wpa_supplicant 0770 system system

I think that ralink wifi driver use the name of rausb0

 

You can try it！

Hi,

     For the moment, I managed to get the driver to work using the linux kernel supplied rt2x00 driver for the kernel. It creates wlan0.

I think the problem might be the name of the ctrl_interface defined in wpa_supplicant.conf file, 

ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=system

and the code that uses of the interface name in wifi.c 

property_get("wifi.interface", iface, "wlan0"); 

this is where it is failing. What have you entered here?

In the board system.prop file, I also have the following entry:

wifi.interface = wlan0

So what do you think the correct entries are in my case? The rtx2000 ralink kernel drivers create a wlan0 interface connection which I can access if I normaly boot in using the linux init process. 

Best regards,

Elvis

Hi,
You can find the full list of modifications that I have made to
android-1.5 so far below.

I am at a loss to figure out why I get the "/data/system/
wpa_supplicant/wlan0": No such file or directory error.

I/WifiHW ( 913): wifi_command called, cmd:LIST_NETWORKS
I/WifiHW ( 913): wifi_send_command, cmd = LIST_NETWORKS
I/WifiHW ( 913): wifi_connect_to_supplicant called
I/WifiHW ( 913): Interface directory = /data/system/wpa_supplicant
I/WifiHW ( 913): Interface name = /data/system/wpa_supplicant/wlan0
E/WifiHW ( 913): Unable to open connection to supplicant on "/data/

system/wpa_supplicant/wlan0": No such file or directory

What could the reason be?

In my wpa_supplicant.conf, I have

update_config=1
ctrl_interface=/data/system/wpa_supplicant/
eapol_version=1
ap_scan=1
fast_reauth=1



Best regards,

Elvis
