Operation Manual

[Tab] key_mgmt=NONE
[Tab] wep_key0=”Your_WEP_Key”
}
Replace Your_WEP_Key with the ASCII key for your wireless network’s WEP encryption. Save the file with CTRL + O, and
then exit nano with CTRL + X.
WEP encryption is extremely insecure. Readily-available software can break the encryption on a WEP-protected network in just a few minutes,
allowing a third party to use your network. If you’re still running WEP, consider switching to WPA or WPA2 for better security.
WPA/WPA2 Encryption
If your wireless network uses WPA or WPA2 encryption, finish the wpa.conf file as follows:
[Tab] key_mgmt=WPA-PSK
[Tab] psk=”Your_WPA_Key”
}
Replace Your_WPA_Key with the pass phrase for your wireless network’s encryption. Figure 4-7 shows an example
configuration for a wireless network with the SSID “Private_Router” and the WPA pass phrase “Private Wireless
Network”. Save the file with CTRL + O, and then exit nano with CTRL + X.

Connecting to the Wireless Network
The Pi’s wireless networking is now configured, and will begin the next time the Pi is restarted. To start the wireless network
without rebooting, type the following:
sudo ifup wlan0
To make sure that the network is operational, unplug the Pi’s Ethernet cable (if attached) and type the following:
ping -c 1 www.raspberrypi.org
If you start having problems with your Pi following the installation of a USB wireless adapter, it could be due to a conflict with other USB devices.
Some adapter models are known to cause problems with certain USB keyboards. For an up-to-date list of adapters that are known to be good, as well
as those that are known to cause conflicts, visit http://www.element14.com/community/docs/DOC-44703/l/raspberry-pi-wifi-adapter-testing or the
