I've lost wlan0 interface on my Raspberry Pi3 - It was working till today, until (most probably) it restarted because it got disconnected from power for a moment. I did last dist-update few weeks ago - but there were several restarts days/weeks after that. I don't recall making any software/config changes.

On GUI I get the information that "no wireless interface found"

sudo ifconfig wlan0 up gives:

wlan0: ERROR while getting interface flags: No such device

uname -a:

(altough in /lib/modules I have only two directories: 4.9.35+ and 4.9.35-v7+)

(Pi was connected wirelessly to router, and there was ethernet cable from pi to my smarttv - smarttv whas using pi's access to internet)

  • There seems to be no mention of any wifi devices in dmesg... what's the result of running dpkg --get-selections | grep firmware? (You might be missing firmware-brcm80211.) – Hydraxan14 Jul 20 '17 at 21:23

Presumably something went wrong during an upgrade Run sudo apt-get update; sudo apt-get install --reinstall raspberrypi-bootloader raspberrypi-kernel will put it back to the latest supported kernel/bootcode.

NOTE This may take a while - BE PATIENT until it finishes.
