Hi, savoy I did in wpa_supplicant.conf and init.rc here goes my wpa_supplicant.conf & init.rc
== external/wpa_supplicant/wpa_supplicant.conf == # global configuration (shared by all network blocks) # # Parameters for the control interface. If this is specified, wpa_supplicant # will open a control interface that is available for external programs to # manage wpa_supplicant. The meaning of this string depends on which control # interface mechanism is used. For all cases, the existance of this parameter # in configuration is used to determine whether the control interface is # enabled. # # For UNIX domain sockets (default on Linux and BSD): This is a directory that # will be created for UNIX domain sockets for listening to requests from # external programs (CLI/GUI, etc.) for status information and configuration. # The socket file will be named based on the interface name, so multiple # wpa_supplicant processes can be run at the same time if more than one # interface is used. # /var/run/wpa_supplicant is the recommended directory for sockets and by # default, wpa_cli will use it when trying to connect with wpa_supplicant. # # Access control for the control interface can be configured by setting the # directory to allow only members of a group to use sockets. This way, it is # possible to run wpa_supplicant as root (since it needs to change network # configuration and open raw sockets) and still allow GUI/CLI components to be # run as non-root users. However, since the control interface can be used to # change the network configuration, this access needs to be protected in many # cases. By default, wpa_supplicant is configured to use gid 0 (root). If you # want to allow non-root users to use the control interface, add a new group # and change this value to match with that group. Add users that should have # control interface access to this group. If this variable is commented out or # not included in the configuration file, group will not be changed from the # value it got by default when the directory or socket was created. # # When configuring both the directory and group, use following format: # DIR=/var/run/wpa_supplicant GROUP=wheel # DIR=/var/run/wpa_supplicant GROUP=0 # (group can be either group name or gid) # # For UDP connections (default on Windows): The value will be ignored. This # variable is just used to select that the control interface is to be created. # The value can be set to, e.g., udp (ctrl_interface=udp) # # For Windows Named Pipe: This value can be used to set the security descriptor # for controlling access to the control interface. Security descriptor can be # set using Security Descriptor String Format (see http://msdn.microsoft.com/ # library/default.asp?url=/library/en-us/secauthz/security/ # security_descriptor_string_format.asp). The descriptor string needs to be # prefixed with SDDL=. For example, ctrl_interface=SDDL=D: would set an empty # DACL (which will reject all connections). See README-Windows.txt for more # information about SDDL string format. # #ctrl_interface=wlan0 ctrl_interface=DIR=/data/system/wpa_supplicant/ GROUP=system == system/core/rootdir/init.rc == # give system access to wpa_supplicant.conf for backup and restore mkdir /data/misc/wifi 0770 system system mkdir /data/misc/wifi/sockets 0770 system system mkdir /data/system 0775 system system mkdir /data/system/wpa_supplicant 0770 system system mkdir /data/misc/dhcp 0770 dhcp dhcp chown dhcp dhcp /data/misc/dhcp chmod 0555 /system/bin/busybox and after booting up, I checked the directory, /data/system/ wpa_supplicant & /data/misc/wifi/sockets both exist but it still can't connect. just don't know why???
