Raspberry Pi 4 - wireless interface not listed

[MariusElvenwood]

Recently bought a new Raspberry Pi 4, installed ALARM using the instructions and I wanted to setup the connection to the WiFi but there's no wireless interface in my list of devices.

[root@alarmpi ~]$ ls /sys/class/net
eth0 lo

Can anyone tell me how to get the WiFi up and running? Ethernet isn't an option at the moment, I don't have access to the router.

Not sure why ...
$this->bbcode_second_pass_code('', ' ls /sys/class/net
eth0 lo wlan0
')

What is the output of:
$this->bbcode_second_pass_code('', 'uname -a')

I had the same issue and read that it usually means a hardware problem, so I threw raspbian on a uSD to check if WiFi shows up in the official image and it did. wlan0 showed up and I was able to connect to my 802.11ac router without issue. Meanwhile, Arch won't give me an interface. Bluetooth seems to initialize correctly, then dmesg just says the following a few times after saying what firmware it's loading for the WiFi chip::
$this->bbcode_second_pass_code('', 'brcmfmac: ht avail timeout ')
The Raspbian image does not give this error.

same problem here.

$this->bbcode_second_pass_code('', '
# uname -a
Linux alarmpi 4.19.57-2-ARCH #1 SMP PREEMPT Sun Jul 14 19:05:33: UTC 2019 armv71 GNU/Linux
')

ARM v7 doesn't look right anyone else see a problem? Thanks a bunch

Looks like RPi 2 is in the instructions and boots but no WiFi.

wget http://os.archlinuxarm.org/os/ArchLinux ... est.tar.gz

RPi 3 image doesn't boot, there is no RPi 4 image.

Should there be a RPi 4 image? Anyone have this working per instructions? Thanks folks!
