The hardware driver support is now in place. The device now needs network
configuration.
Configuration
You could edit the configuration files by hand if you knew all the possible keywords
necessary for your particular wireless authentication protocol. The following Linux
raspberrypi 3.2.27+
files are involved:
Pathname
Description
/etc/network/interfaces
Main configuration file for networks
/etc/wpa_supplicant/wpa_supplicant.conf
Authentication information
You'll find a variety of advice on how to configure these on the Internet. But the
quickest path to success is to just use the wpa_gui dialog box from the Raspberry Pi
desktop. Once you've done it this way, directly editing the configuration files can be
performed later if you need to tweak it further.
Figure
7-1
shows how to locate the
wpa_gui
dialog box from your Pi desktop. Once
wpa_gui
is started, click the Manage Networks tab, shown in Figure
7-2
. If you've made
prior attempts at configuring
wlan0
, delete them all from this menu. Then click the Scan
button at the bottom right.
