Manually config to connect wireless router

To use RR(lite) to connect to your wireless router, you need to do the following:

   apt-get install wireless-tools
   apt-get install wpasupplicant
   ifconfig wlan0 up

Now you can view is the wifi module works by scanning the AP nearby

   iwlist wlan0 scan

edit /etc/wpa_supplicant.conf

   ctrl_interface=/var/run/wpa_supplicant
   network={
   	ssid="your ssid name"
   	psk="your wireless password"
   }

and then run

   wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf 

to connect to the wireless router.

If you want to set the RR to connect to the wireless router automatically every time it boot up. Add the following to the /etc/network/interfaces

   auto wlan0
   iface wlan0 inet dhcp
   wpa-conf /etc/wpa_supplicant.conf
