(Replace the "_SSID_" and "_WPA_SHARED_KEY_" text with your actual SSID and WPA key values.) network= sudo nano /etc/wpa_supplicant/wpa_nfĪdd the following data to this wireless configuration file. Use the following command to create (or edit) this file. Wpa-roam /etc/wpa_supplicant/wpa_nfĪfter modifying the network interface configuration file, we need to create the wireless configuration file. Make sure the following lines are added to ( or un-commented in) your file auto wlan0 One you have installed the adapter, verified the kernel driver is loaded, and confirmed that a wireless network interface ("wlan0") is available, you will need to configure the wireless connection settings to securely connect to your wireless network.įirst, let's open the network interfaces configuration file for editing using the following command: sudo nano /etc/network/interfaces Now we are ready to move on to the configuration steps. We are just looking to ensure that the "wlan0" adapter is present. If not, try removing and re-inserting the Airlink 101 USB adapter.Īs a final validation check to make sure that the Airlink 101 adapter is ready to use, send the "iwconfig" command to display a listing of the current wireless network configuration. You should see the "8192cu" kernel module loaded. Use the following command to list the kernel modules: lsmod Now that we have verified that the Airlink 101 adapter is recognized, lets check to make sure the kernel driver is loaded. This is the chipset used by the Airlink 101 adapter. You should see the RealTek RTL8188CUS 802.11n WLAN Adapter device listed in the output. Use the following command to verify that the Pi "sees" the Airlink 101 WiFi adapter. Next, lets make sure that the Raspberry Pi recognizes the device. Insert the Airlink 101 USB adapter into your Raspberry Pi's USB port.
(If you are using a different distribution or an older distribution you may have to install the Linux driver for the Realtek RTL8192CU driver.) This greatly simplifies the installation.
The latest Raspian distribution ( Raspbian “wheezy” ) already includes the drivers for this adapter pre-installed.
