Raspbi3 B+ and Wifi

Software
1

Could anybody with the new B+ model please test, if wlan0 shows up?
In my case, ifconfig only shows eth0 and lo.
I need to know, if I have to return the raspbi or if I have to wait for a software update.

Just a fast look at my RPi3B+:

root@teq:~# ifconfig

        inet 192.76.176.156  netmask 255.255.255.240  broadcast 192.76.176.158

root@teq:~# ifconfig wlan0
wlan0: error fetching interface information: Device not found

Had to comment out this line in /boot/config.txt:

dtoverlay=pi3-disable-wifi

… but did not help. Perhaps because:

root@teq:~# dmesg | grep brcmfmac

Ok, only way I found to got it working (link):

wget https://archive.raspberrypi.org/debian/pool/main/f/firmware-nonfree/firmware-brcm80211_20161130-3+rpt3_all.deb
sudo dpkg -i firmware-brcm80211_20161130-3+rpt3_all.deb

What image are you using?

@C0d3man, have you tried a “rpi-update” ?

7

Yes, rpi-update won’t help :neutral_face:

8

It is not a Zynthian. I made this in February, a Minibian based small setup for a Pianoteq-only.

@jofemodo,

I can confirm, that a rpi-update doesn’t help.
Could you add his fix?
I don’t want to apply it myself, because i want to keep a valid test base.
