My boss wanted me to install Raspbian through raspbian ua net install, instead of through NOOBs. It just got done installed a base-level Raspbain from sources files and its LXDE gui.
However, I have a Wi-Pi adapter plugged in and there is no wireless connection. The Gui says that "device is not ready (firmware missing)".
Also I tried to run lspci and it came back with
pcilub: Cannot open /proc/bus/pci
lspci: Cannot find any working access method
Before continuing with this answer, type the command lsusb and make sure the adapter is listed.
Sometimes the RPi does not recognize Wi-fi adapters in the GUI, but this doesn't mean you cannot use them. You will just have to edit system files manually instead.
So, first edit your wpa_supplicant file be entering the command
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
then, add this to the bottom:
network={
ssid="NETWORK"
psk="PASS"
}
Obviously, you need to replace "NETWORK" your your network name and "PASS" with your network's password.
Finally, edit your interfaces file by typing the command:
sudo nano /etc/network/interfaces
And, if this isn't already there, add this:
allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
Reboot the Pi and it should connect to your network.
