[SOLVED] WiFi not working.

[Geronius]

Hi, John-

I've experienced this before as well. What I've found is that the key is always in the settings in the OpenPlotter configuration application, specifically on the "network" tab.  It obviously depends on your application, but the setting "client" is what I usually need/want, and once set, allows me to do exactly what I want - have the OpenPlotter Raspberry Pi join my existing network.  Your mileage may vary.

Good luck!

Same experience here. After fresh install it was impossible to set WIFI language to DE - "Could not communicate with wpa_supplicant"
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.
