No wireless interface on RPi3

Sat Apr 08, 2017 6:33 am

Hi all,

Got an RPi 3B for Christmas and found time to try and set it up finally. Apparently it comes with a WiFi chip but I've been having lots of trouble setting it up. When I do ifconfig -a I only see lo eth0, and there's no wlan0 interface. I tried to modprobe brcmfmac brcmutil cfg80211 but to no avail, and dmesg doesn't return anything helpful :/ Also I tried using ethernet to update the system (hoping there would be firmware updates) and it connected/updated fine, but that didn't do anything to solve the wifi problem. Any suggestions? I'm fairly comfortable with Linux/Arch but this just perplexes me. I think it has something to do with the kernel modules but I'm not totally sure. Everywhere I've looked on the Internet so far has lead to a dead end or hasn't worked :(

Any help would be appreciated!

Install a fresh Raspbian with Pixel. When clicked, does the WIfi icon top right give a list of available access points?

Thanks for the quick reply! Yes, it does. Well at least it's not a hardware issue then. Maybe I should just use Raspbian for the time being? I'd really like to be able to use Arch at some point though.

WiFi is supported so maybe you are running an old version of ArchLinuxArm ??

Or maybe you have not updated with the latest kernel /firmware, Arch being a rolling release it updates frequently ??

Code: Select all

sudo pacman -Syu

Yes that was the first thing I did, I plugged it into ethernet and updated it. I got the tar file right off the ArchArm site so it should be the most recent one :/

EDIT: Wait was I supposed to use the ArchLinuxArm-rpi-2-latest.tar.gz? There's some contradictory info there on the site

ArchlinuxArm expect a user to create a SD Card using a Linux System and yes they use the same ARMv7 AArch32 release for Raspberry Pi 2B & 3B

Unless you want to try the experimental ARMv8 AArch64 release !!

Oh ok so I went to their Downloads page and downloaded the package under ARMv8 Raspberry Pi 3 (ArchLinuxARM-rpi-3-latest.tar.gz) originally. I guess I'll try the package under ARMv7 Raspberry Pi 2 then? Ugh sorry I'm dumb :roll:

Return to “Arch”
