Dear Community,

I have and Toradex Apalis iMX8QM V1.1C 4GB WB IT and an Ixora 1.1A. Although my iMX8 is a WB version, I can’t find any wifi interfaces.

iw dev

and

nmcli device wifi list

commands don´t show anything. However, it seems that wifi modules are loaded:

root@localhost:~# lsmod

How can I bring up the wifi interface?

Thanks in advance,

Hi @Andermutu !

From your command lines, seems like you built your own image using Yocto (root@localhost). Is that right? The reference images present the module type and serial number at the beginning of command lines.

I took an Apalis IMX8QM v1.1B 4GB WB IT and installed the Reference Minimal Image 5.4.0+build.11 (dunfell). nmcli is not available, but here is what I got.

Using iw:

root@apalis-imx8-06804757:~# iw dev
phy#0
        Interface uap0
                ifindex 6
                wdev 0x2
                addr d8:c0:a6:cf:7a:4f
                type AP
                txpower 0.00 dBm
        Interface mlan0
                ifindex 5
                wdev 0x1
                addr d8:c0:a6:cf:78:4f
                type managed
                txpower 0.00 dBm

Using lsmod:

root@apalis-imx8-06804757:~# lsmod

Using connmanctl:

root@apalis-imx8-06804757:~# connmanctl
connmanctl> enable wifi
Error wifi: Already enabled
connmanctl> scan wifi
Scan completed for wifi
connmanctl> agent on

    reptree_back         (wifi network's id)
    reptree_back         (wifi network's id)
connmanctl>

You can see that it is working properly. If you really have built your own image, it is worth checking if maybe you disabled something related to the wifi. Also, take a look at the attached article that can be handy for dealing with wifi :slight_smile:
