This short tutorial will introduce how to set up Wireless Lan on a Fedora-driven Cubietruck. The aim is to load the necessary module and set-up the connection to a Wireless network during system startup automatically.

First of all, the module for the Broadcom AP6210 chipset (offering Bluetooth and Wireless functionality) must be added to the /etc/modules-load.d/cubie.conf config file

nano /etc/modules-load.d/cubie.conf

Check, that „bcmdhd“ is included in this file.
During next system reboot, the WiFi module will be loaded automatically.
Currently (before the reboot) we need to load the module manually by:

modprobe bcmdhd

Checking, if the module was loaded successfully (module name should appear in the command line):

lsmod |grep bcmdhd

In the next steps, we are going to install and configure WPA supplicant and Wifi Radar

yum install wpa_supplicant
yum install wifi-radar

Add your network and password to the file /etc/wpa_supplicant/wpa_supplicant.conf:

nano /etc/wpa_supplicant/wpa_supplicant.conf


network={
ssid="ssid_name"
psk="password"
}

In the next step, some minor changes to the /etc/sysconfig/wpa_supplicant are necessary:

nano /etc/sysconfig/wpa_supplicant


INTERFACES="iwlan0"
DRIVERS="-Dwext"
OTHER_ARGS="-f /var/log/wpa_supplicant.log -P /var/run/wpa_supplicant.pid"

In addition, the network setting for your wireless interface needs to be included into the ifcfg-file

nano /etc/sysconfig/network-scripts/ifcfg-wlan0


DEVICE=wlan0
ONBOOT=yes
BOOTPROTO=dhcp

Disabling and stopping the Network Manager:

systemctl disable NetworkManager.service
systemctl stop  NetworkManager.service

Now we can test, if the WLan was started and the network connection was established:

wpa_supplicant -B -i wlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf -D wext 
dhclient wlan0

To run the commands on system startup, add wpa_supplicant to the services:

systemctl enable wpa_supplicant.service

You can also check for Wifi networks available in your environment by invoking:

iwlist wlan0 scan
