Raspberry Pi 3 and wlan0 no longer showing up

Sat Mar 19, 2016 10:03 pm

Ok, so I got my RPi3 a few days ago. The first disappointing issue was that none of my existing RPi2 SD cards would boot. I even upgraded one from Wheezy to Jessie, but no dice. And, as if that wasn't bad enough, I just did an aptitude upgrade and now the on-board wifi interfaceis not showing up. I saw that there was an update to BCM80211 drivers, thought nothing of it until I powered off and then powered on and ifconfig only shows lo and eth0 interfaces. wlan0 is no where to be found, even via iwconfig. Wifi and the wlan0 adapter all showed up and worked fine before today's upgrade. Any insights on how to fix this would be helpful. I see the modules being loaded via lsmod

Code: Select all

Have the same issue - no wlan0 in ifconfig on RPi 3.
I just took the card from Rpi 2 and put it into my new Rpi 3, ran all updates and upgrades and figured that everything apart from WiFi works.
Any ideas?

If you've previously run Wheezy on that image then you might still have a /etc/udev/rules.d/70-persistent-net.rules which is claiming the wlan0 name. Edit or delete that file.

Jessie works pretty much as described in this proposal. If might be worth booting Jessie with "net.ifnames=1" appended to /boot/cmdline.txt and seeing if the interface is present then.
