Unlike in the first post, we will make no changes to this file. Sudo apt-get install wpasupplicant wpagui Configuring the New WiFi AdapterĮxamine the contents of the ‘/etc/networks/interfaces’ file, by entering the following command: Sudo apt-get update & sudo apt-get upgrade The upgrade command might take a few minutes if you haven’t run this on your RaspPi in a while. Note this will check for any upgrades to the RaspPi’s existing software, first. To install ‘wpa_supplicant’ and the ‘wpagui’, enter the following commands. The particular software is referred to as ‘wpa_supplicant’. Installing Wireless LAN Security Protocol SoftwareĪs detailed in the earlier post, we need to install software that allows us to configure and connect to our WPA/WPA2-secured wireless network. You can insert the WiFi Module at this point in the process. Remember to select #1 when asked to choose a card type:

It allows you to edit the same configuration from a gui, just as we will do manually in the command shell.Ĭopy the ‘Linux and Android’ Realtek driver folder from the CD, supplied by the manufacturer, to the ‘tmp’ folder on the RaspPi using WinSCP. If you’re not comfortable configuring networks from the command shell, you can also use the wpa_gui application (aka wpa_suppicant user interface) from the RaspPi’s desktop. This allowing the RaspPi to roam from networks to network, automatically connecting to those that are configured. You can add multiple WLAN configurations to the wpa_supplicant configuration file.

This involves adding the WLAN configuration to the wpa_supplicant configuration file (‘/etc/wpa_supplicant/wpa_nf’). Recently, while installing the same type WiFi Module (WNIC) on a RaspPi running Raspbian “wheezy”, I chose the alternate method. I chose the simple method of hard-coding a single WLAN configuration into the ‘/etc/interfaces’ file. As I mentioned in that post, there was more than one method of configuring the WiFi Module (WNIC) on a WLAN, based on the research I did. In a earlier post, Installing a Miniature WiFi Module on the Raspberry Pi (w/o Roaming Enabled), I detailed the installation and configuration of a Miniature WiFi Module, from Adafruit Industries, on a RaspPi running Soft-float Debian “wheezy”.
