I have an Edimax USB WiFi adapter on my Raspberry Pi 2B, in Germany. The adapter works and is able to list nearby networks (
iwlist wlan0 scan).
It shows all my neighbors' networks, except mine. The WiFi strength is excellent (I'm using on my phone), the SSID is not hidden (I can see it from my phone) and it's on channel 12. wpa_gui shows the same scan list. Security is WPA2 PSK CCMP. Restarting the router didn't work.
If I just blindly set the wpa supplicant it won't connect either.
Any idea what could be causing this?
