I setup 16.04 beta 2 and I have been unable to find the internal WiFi (or bluetooth)
networking is OK (works with a dongle Wifi)
dmesg didn’t show anything that looked like a wireless or bluetooth device being loaded.
lsusb shows nothing
lshw shows nothing
iwconfig no wireless
looked in /boot/config.txt (did I miss it?)
did apt-get update & upgrade
did rpi-update
I haven’t been able to see much documentation on the internal hardware.
i would like to know if this going to be configured in the device tree.
It would be nice if someone produced a checklist of what is necessary to bring them up.
Thanks for any help.
To see your bluetooth try:
$ hcitool dev
Devices:
hci0 B8:–:--:–:--:–
also try $ sudo lshw -short
should show your wlan like:
system Raspberry Pi 3 Model B Rev 1.2
/2 wlan0 network Wireless interface
/3 eth0 network Ethernet interfac
and in dmesg, its brcmfmac i think
as i get messages like:
[ 6.078205] usbcore: registered new interface driver brcmfmac
[ 9.034623] brcmfmac: brcmf_add_if: ERROR: netdev:wlan0 already exists
EDIT: You can also try “hwinfo” (sudo apt-get install hwinfo)
$ hwinfo --short
network:
eth0 Standard Microsystems SMSC9512/9514 Fast Ethernet Adapter
network interface:
wlan0 WLAN network interface
eth0 Ethernet network interface
lo Loopback network interface
Nothing shows

I even removed the usb wireless keyboard, rebooted and tried again thinking that it may have interfered, still nothing.
Weird, did you Install 16.04 for sure? If you haven’t done anything so far, just try writing the image to the sd again? Do a fresh start I mean.
It’s just that we all have the same hardware, unless yours is broken. It should totally work right away. Since we used the same image on the same hardware…
but I’m no linux expert, only a programmer…
I got this same error after upgrading a fresh install of Ubuntu Server 16.04.
To anyone that runs into it as well, I found a solution to the problem at this url: https://www.raspberrypi.org/forums/viewtopic.php?p=939041#p939041
Could you clarify which distro you started from, what you did, and what tests you applied.
I’m not aware of a Ubuntu-Mate 16.04 server edition for the Pi3,
and my two 16.04.02 LTS installations on SD cards for Pi3 have worked with no network anomalies.
