The RPi3 WiFi stopped working after upgrade; pacman -Syu yesterday!
Here seems to be what has caused this:
$this->bbcode_second_pass_code('', '[root@raspberrypi:log]# grep raspberrypi- pacman.log |tail -3
[2017-04-24 02:48] [ALPM] upgraded raspberrypi-firmware (20170428-1 -> 20170613-1)
[2017-06-27 04:06] [ALPM] upgraded raspberrypi-bootloader (20170613-1 -> 20170626-1)
[2017-06-27 04:07] [ALPM] upgraded raspberrypi-bootloader-x (20170613-1 -> 20170626-1)')
I'm unable to figure out, but I think, raspberrypi-bootloader and raspberrypi-bootloader-x might be the reason. I have double checked hardware is working fine using Rasbbian, otherwise
