  • ##General Connection Using lsusb to look up your wifi adapter device name:

    $ lsusb

    You will see your device name such as Wlan0, but the IP address is still empty.Using the commend to modify the configuration file:

    $ sudo nano /etc/network/interfaces

    The file should contain such context:

    auto lo
    iface lo inet loopback
    iface eth0 inet dhcp
    auto wlan0
    allow-hotplug wlan0
    iface wlan0 inet dhcp
    wpa-ssid "SSID"
    wpa-psk "password"

    After this, the pi will take a DHCP auto connection. Make sure type the right SSID and password. The IP address will be allocated automatically.Using the command to restart the network.

    $ sudo /etc/init.d/networking restart

    If the terminal says done, you can enjoy wifi with your PI now.

    ##Connect to University endroam In University of Liverpool, the wireless network called “eduroam” is applied. Actually this wireless network is applied in most universities in Europe. So here is the method to config “eduroam” for Raspberry Pi. Firstly, find the information about your university network. For example:


    Download the certificate, copy or move the certificate file: e.g. :

    $ sudo mount /dev/sda2 /mnt/usb/  #mount the udisk to your file
    $ cd /mnt/usb/
    $ sudo cp /your direction/certificate.cer /etc/wpa_supplicant

    Then, you can use either GUI WifiConfig in the desktop, or edit the wpa_supplicant.conf:

    $ sudo gedit /etc/wpa_supplicant/wpa_supplicant.conf

    Add the code below to the file:

            identity="your university login name"
            password="your password"
