[SOLVED] WiFi not working.

[StoneCrab]

No wlan0 Wireless adapter was visible and /etc/wpa_supplicant was unchanged (remained set to default country=GB)

• updated all packages from within Raspbian and from OP (about 200 MB) 
  
• changed network setting in OP to 'client' 
  
• edited /etc/wpa_supplicant to look like this
  

Code:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=DE

network={
    ssid="xxxxxxxxxx"
    psk="yyyyyyyyyy"
    key_mgmt=WPA-PSK
}

only after completing all above mentioned steps (and reboot) wlan0 came alive and connected flawlessly

cheers,
G.

I am having the same problem with the network not accepting the WiFi Country setting and not showing any of the available networks.  

Looking at G's code, I went into /etc/wpa_supplicant directory where I found a file called wpa_supplicant.conf. This file was edited with sudo nano where I entered G's code.  The second portion of the code where network= isn't explicitly stated, but I assumed that this would set the SSID and password for my pi on the WiFi (and is NOT the wifi that I want to connect to)  Please correct me if I am wrong here.  

I saved the modified text to wpa_supplicant.conf and then rebooted.  After the reboot, I still have the red X's where the network configuration is located in the upper right corner of the desktop.  It is STILL reporting that the WiFi country is not set.  When I click to set the Wi-Fi country, the default now comes up as the US (it used to be GB), so editing the supplicant file did something but it didn't fix the problem for me.

I do want to be able to run the Pi with OpenPlotter and as an Access Point so I can go headless, but I still want to be able to update the files, charts, grib etc, so I still need to be able to get on the network.  

Any ideas?
