I have a raspberry pi 3 that I was using as hostspot. Today I booted it and the wlan0 interface is gone when typing
ip a
When doing raspi-config and try to configure a wireless interface, I receive the message:
No wireless interface found
I downloaded a new image of Raspbian and copied it into my SD card but still I can only see eth0. I also updated the firmware with:
sudo rpi-update
And rebooted but still, just eth0.
When I check my connected USB devices I see 4:
- SMSC9512/9514 Fast Ethernet Adapter,
- SMC9514 Hub,
- Linux Foundation root hub,
- Keyboard
Shouldn't there be a 5th one pointing to the wlan device? Any idea what else I could check? Is perhaps my wlan chip broken?
Here is my dmesg: https://pastebin.com/k3uaJUrh

After checking this useful thread, it seems it is really broken ==> https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=171482&sid=f7e7e556a7b52d9af452012f3d8d3aa4
journalctl -b
why the wlan0 interface isn't detected?sudo apt update && sudo apt dist-upgrade -y
that will get new firmware for the WiFi chip. Try downloading a fresh copy of plain Raspbian or plain Raspbian Lite, write that to a new SDCard and boot it. Does WiFi work with a fresh start?brcmfmac
when viewing journalctl. This is the wifi driver and it loads the firmware.
