Make sure the Pi recognized your wireless USB adapter.

dmesg | grep 802.11
[ 2.51875] usb 1-1.3: Product: 802.11n WLAN Adapter

This means that the operating system recognized the USB WiFi Adapter using one of the built-in drivers. All that is left is to configure your WiFi connection.

Go ahead and boot your RasPi with Pidora on your SD card, your USB wireless interface plugged in, and a wired Ethernet connection. Open a terminal window and gain root privileges.

yum install net-tools

I found the default Pidora lacks the command “ifconfig” and it’s rather frustrating to say the least. This first step may or may not be needed, but they are useful tools nonetheless. Loading net-tools now gives you the “ifconfig” command among others.

Run the “service network status” command to make sure wlan0 is active

service network status
Currently active devices:
lo eth0 wlan0

To connect to your wireless router, enter the command:

nmcli dev wifi con “thessid” password “mywifipassword”

Where “thessid” is the SSID of your hotspot, and “mywifipassword” is the plaintext password needed to access it. That’s all there is to it! You should see a bubble notification that you are now connected to the wifi network and a signal meter will be located at the top right of your screen. You can also run “ifconfig” to see that your wlan0 interface is getting an IP address.

Unplug your ethernet cable and enjoy the wireless from your Raspberry Pi!
