Macbook12 macvlan Parent network card

Hallo,

Started to bring my home-automation via Raspberry in Docker.

Therefore I reused an old macbook12 ( 8,1 2015 ) and installed as OS Ubuntu 24 - Running well using WiFi

I installed docker and portainer. And did the first examples via homebrige and iobroker in host mode, also run.

Now I want to setup a macvlan. Used some youtube videos and a German version of a ip calculator http://jodies.de

I search for the parent network card via ifconfig:

I indentify the enx5c5310751877 as LAN and the wlp1s0 as WiFi network cards there.

When I generate in portainer - network - a macvlan for LAN everything is workig and I can connect a container via the macvlan and i get a ip-adress from the range and and can ping and work from my network.

When I delete the LAN Network and want to do the same for WiFi network card. The network is setup and I also can add it to the container. But then I can’t ping in my network or also 8.8.8.8.And I’m also not reachable.

Any idea what I made wrongly?

As far as I know, MAcVLAN requires wired networks. Maybe IPVLan could work.

This blog post describes it in detail:

The major takeaway is

Most likely the driver does not support the AP mode and 4addr.
