Every time I reboot my librem5 the USB connection gets different MAC address. What’s ever weirder is that both ends of connection (my laptop and librem5) have different MAC addresses.
- on laptop: 1E:6C:7D:D9:0E:01, on librem5: ea:c8:8e:c0:bc:53
after librem5 reboot:
- on laptop: 9A:31:DF:7F:FF:E3, on librem5: 22:5f:24:be:a8:a0
I found topics on this forum about changing MAC addresses, but they are related to wifi interfaces. Also
man NetworkManager.conf says
ethernet.cloned-mac-address If left unspecified, it defaults to "preserve".
So I guess this is something that comes from usb driver, not NetworkManager (but I might be wrong here).
Obviously, I’d like to have the same MAC address every time I connect, so that it’s automatically handled by my custom connection specification in NetworkManager on my laptop.
