Linux Wi-Fi Works With wicd - Page 2
Identifying a Wireless Interface
To find the name of your wireless interface:
wlan0 IEEE 802.11g ESSID:""
Non-wireless interfaces will say "no wireless extensions". To figure out what your wireless driver is:
$ lscpi -i | grep wireless
03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network
Connection ( rev 02 )
From here it's all gravy. Every time you're in a new location, wicd will scan and locate all available networks for you. Connect with a mere click on the Connect button, and with luck a little connection icon will appear in your systray. (If it doesn't, the FAQ tells you how to fix it). If you hover your cursor over it, or click on it, you'll see complete connection statistics. The Wicd Manager interface is a bit confusing, because the Connect button does not change to Disconnect, though there is a Disconnect button up top. As you can see in Figure 1, connection status is also displayed at the bottom of the Wicd Manager screen.
Encryption key management is a very nice feature, though it still has some rough edges. If all goes well, all you need to do is select the correct type of encryption and then enter the appropriate authentication information, such as the path to your encryption key, login and password, whatever you need to do. If you can't make it work, you may need to edit the encryption templates in /opt/wicd/encryption/templates. If you're experienced with wpa_supplicant it won't be a big deal, and the best help resource is the wicd forums; you'll find plenty of help there with any encryption problems.
