Unfortunately, the wlan0 interface is missing:

It’s not available in rfkill:

khadas@Khadas:~$ rfkill list

        Soft blocked: no
        Hard blocked: no
1: hci1: Bluetooth
        Soft blocked: no

And there’s nothing in the kernel logs about it:

khadas@Khadas:~$ dmesg | grep wlan
khadas@Khadas:~$

Of course, NetworkManager can’t see or manage it either:

Any suggestions? I can try the “desktop” image if that’s likely to be different somehow.

@rcoder The Wi-Fi of VIM3L is not very stable. When I tested it, it sometimes worked and sometimes failed.

rcoder · May 21, 2022, 4:01am

Sorry, I’m a little unsure of your meaning.

“WiFi…is not very stable” meaning the board is unreliable, or that it simply fails to work reliably under the current Khadas-suggested Ubuntu kernel?

I ran this exact same board in a different project more than six months ago and WiFi definitely worked.

I’m starting to think that I need to spend some quality time with the Fenix toolkit again, as between this and some NVMe compatibility issues I’ve hit in recent weeks I suspect there is some kernel patching + compiling in my future.

hyphop · May 21, 2022, 4:06am

we need to check last changes for mainline kernel , and prepare patch , its just a kernel problem

foxsquirrel · May 21, 2022, 11:28am

What happens when you do this?

nmcli device wifi connect {ssid} password "[password]"

rcoder · May 21, 2022, 7:36pm

That…worked? Thanks, @foxsquirrel.

I’m somewhat mystified as to why the interface flat-out did not appear in any other configuration view – including nmtui – until running the above, but TIL to try nmcli first.

…at least until I switch away from having NetworkManager in the loop at all, as I’ll do shortly. (I prefer using systemd-networkd once I have >2 interfaces to manage, and this board is going to be running a few VMs + at least one Wireguard tunnel.)

foxsquirrel · May 21, 2022, 10:30pm

Check nmcli for autostart of wifi. It “should” be on by default, not sure why this happens.

These are good networking platforms, I hope a future model will have at least 2 non-shared 1gb ethernet ports.

hyphop · May 23, 2022, 2:50am

sure no

latest images with latest mainline kernel have problems with wi-fi
please check dmesg | grep brcm messages

I have the same problem on khadas vim3l, ubuntu 22.04, 6.1 kernel, 1.4 fenix.

But if I reload brcmfmac, wlan0 will appear again.

modprobe -r brcmfmac
modprobe brcmfmac
