1. Connect your Pi with an ethernet cable to a switch and boot up.
2. Connect to console using user: root and password: raspberry.

3. Upgrade MINIBIAN:

   apt-get -y update
   apt-get -y upgrade
   

4. Install packages: apt-utils, apt-file, raspi-config, usbutils, wpa_supplicant, crda, mc:

   apt-get -y install apt-utils apt-file raspi-config \
    usbutils wpasupplicant crda mc
   

5. Setup wlan0:

   cat <<EOF >> /etc/network/interfaces
   
   auto wlan0
   allow-hotplug wlan0
   iface wlan0 inet dhcp
   wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
   
   EOF
   

6. Configure wpa_supplicant (replace YOUR-WIFI-SSID and YOUR-WIFI-PASSPHRASE):

   wpa_passphrase YOUR-WIFI-SSID YOUR-WIFI-PASSPHRASE \
    >> /etc/wpa_supplicant/wpa_supplicant.conf
   

7. Bring up wlan0

   ifup wlan0
   

8. Setup the local timezone

   cat /usr/share/zoneinfo/Europe/Warsaw \
    > /etc/localtime
   

9. Disable debug messages on first console:

   sed -e 's#^exit 0#/bin/dmesg -n 1\n\nexit 0#g' \
    -i /etc/rc.local
   

10. Make mcedit the default editor:

    update-alternatives --remove-all editor
    update-alternatives --install \
     /usr/bin/editor editor /usr/bin/mcedit 10
    

11. Expand the root partition:

    raspi-config --expand-rootfs
    

12. Re-read the partition table:

    partprobe /dev/mmcblk0
    

13. Resize the filesystem of the root partition:

    resize2fs /dev/mmcblk0p2
    

14. Update the firmware of your Raspberry Pi and delete all modules except the latest installed:

    apt-get -y install rpi-update 
    PRUNE_MODULES=1 rpi-update
    

15. Clean-up

    rm -rf /boot.bak
    apt-get clean
    rm -rf ~/{.cache,.config,.local}
    rm -f ~/{.bash_history,.selected_editor}
    

16. Reboot

    shutdown -r now
    

If you encounter problems with your WiFi adapter, it’s probably caused by missing firmware (you can check this by running dmesg). Installation of firmware-ralink or firmware-realtek packages may be required.
