Automatic WLAN Connection on Startup – Linux without GUI

  1. First you need to make sure that you have installed the required packages for secure Wireless connections:

    sudo aptitude install wpasupplicant
  2. Now you need to open the /etc/network/interfaces file in a text editor:

    sudo nano /etc/network/interfaces
  3. Just add the following lines:

    auto wlan0
    iface wlan0 inet dhcp
        wpa-ssid NetworkName
        wpa-psk NetworkPassword

Gigaset USB Stick 54 – Linux

To run a Gigaset USB Stick 54 under Linux you need to execute the following steps:

  1. The Chipset is zd1211rw. You need to get the appropriate firmware. Furthermore you need the wireless tools to manage the stick

    aptitude install wireless-tools zd1211-firmware

    If you cannot find the zd1211-firmware you need to use other sources. For Debian you would need to include non-free.

  2. Now connect the device to your system. It should automatically load the kernel module. To verify check if you can see wlan0 when executing the following command:

    iwconfig
  3. Now you just need to start the interface:

    ifconfig wlan0 up

  To connect to a Wireless network you still need to configure it. The easiest way to do it is with the NetworkManager under Gnome.
