how to enable WIFI module of A13-OLinuXino_Rev_C

[kimdou]

i'm newbie of linux, successfully made a SD card image according to olinuxino-debian.pdf

Device Drivers -> network device support -> wireless LAN -> realtek RTL8192CU/RTL8188CU USB wireless network adapter is enabled
and the .config modified:
CONFIG_TRL8192CU=m
CONFIG_RTLWIFI=m
CONFIG_RTLWIFI_DEBUG=y
CONFIG_RTL8192C_COMMON=m

after transfering the image to SD card,
apt-get instal l wpasupplicant
nano /etc/network/interfaces
auto wlan0
i f a c e wlan0 i n e t dhcp
wpa−d r i v e r wext
wpa−s s i d ......
wpa−psk "....."

but ifconfig -a can't find the WLAN0!


git brach -vv :
stage/sunxi-3.4 e37d760 ..........

It won't necessarily be wlan0, maybe wlan1 etc.
Are those spaces between letters or just a typo?

i f a c e wlan0 i n e t dhcp

there's no spaces in the interfaces file, i want to know whether the WIFI driver is ok.

Please show the complete output from the command:  ifconfig -a

Hi there,

1.  Connect to A13 via USB to serial cable  RX - green to TX, TX - red to RX and Blue to GND.
(P/N USB-SERIAL-CABLE-E-F)
Connect to UART 1 (near the VGA port)
2.  connect to power 12V
3.  Set PUTTY to connect at the COM port (e.g. COM33) at baud rate 112500,
4.  edit the file /etc/network/interfaces
e.g.

uncomment #wlan13 in my case

auto eth1
iface eth1 inet dhcp

auto wlan13
iface wlan13 inet dhcp
wpa-ssid <your SSID>
wpa-psk <your passphrase>

5.  lastly, invoke /etc/init.d/networking restart

root@debian:/etc/network# /etc/init.d/networking restart
Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces ... (warning).

you could now SSH over Wifi to do your necessary other work etc.

Hope I could help.
