I am trying to get working my raspberry pi. I did sudo apt-get update && sudo apt-get upgrade and now the wifi stopped working. I also plugged in the camera if that's not a problem.

dmesg doesn't show anything about wlan0.

if I do sudo ifdown wlan0 && sudo ifup wlan0 I get this:

ifdown: interface wlan0 not configured
wpa_supplicant: /sbin/wpa_supplicant daemon failed to start
run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1
Failed to bring up wlan0.

I didn't touch the /etc/network/interfaces file so it's as default like this:

interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto lo
iface lo inet loopback

iface eth0 inet manual

auto wlan0
iface wlan0 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan1
iface wlan1 inet manual
    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

Any ideas what should be wrong?

EDIT Also if I do ifconfig, wlan0 is not there

  • What model of RPi and what wifi adapter are you using? It sounds like a driver is missing. Are you possibly using a wifi adapter that requires a driver that's not available for the newer versions? – bobstro Feb 18 '17 at 21:41
  • Use ip link, not ifconfig. The latter will only show interfaces that are currently up. – goldilocks Feb 19 '17 at 09:26
