PostPosted: Wed Nov 06, 2024 5:12 am    Post subject: Giving wlan0 priority over eth0 Reply with quote

I have installed Gentoo on my RPi5. The Pi has a connection for the ethernet cable and wifi. I have them both connected and they both have different local ips so for example eth0 has 192.168.1.10 and wlan0 has 192.168.1.11. My wifi connection is faster so I would like to use this is as the default interface but every time I boot it defaults to eth0. Does anyone know how I can set this up. I did it before with NetworkManager by using nmcli and setting a priority so I'd like to see if I could do something similar with iwd instead of having to switch to NM.

Have you tried with nmcli?

I don't use wifi for my rpi5, but nmcli does show
Code:
rpi5 ~ # nmcli
end0: connected to Wired connection 1
        "end0"
        ethernet (macb), 2C:xx:xx:xx:xx:xx, hw, mtu 1500
        ip4 default
        inet4 192.168.xx.xx/24
        route4 192.168.xx.0/24 metric 100
        route4 default via 192.168.xx.xx metric 100

docker0: connected (externally) to docker0
        "docker0"
        bridge, 02:42:C0:5D:C6:4F, sw, mtu 1500
        inet4 172.17.0.1/16
        route4 172.17.0.0/16 metric 0
        inet6 fe80::42:c0ff:fe5d:c64f/64
        route6 fe80::/64 metric 256

lo: connected (externally) to lo
        "lo"
        loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536
        inet4 127.0.0.1/8
        inet6 ::1/128

wlan0: unavailable
        "Broadcom Wi-Fi"
        wifi (brcmfmac), xx:xx:xx:xx:xx:xx, sw disabled, hw, mtu 1500

DNS configuration:
        servers: 192.168.xx.xx
        domains: home
        interface: end0

Use "nmcli device show" to get complete information about known devices and
"nmcli connection show" to get an overview on active connection profiles.

Consult nmcli(1) and nmcli-examples(7) manual pages for complete usage details.
rpi5 ~ #


And networkcli show
Code:
rpi5 ~ # networkctl
IDX LINK    TYPE     OPERATIONAL SETUP   
  1 lo      loopback -           unmanaged
  2 end0    ether    -           unmanaged
  3 wlan0   wlan     -           unmanaged
  4 docker0 bridge   -           unmanaged

4 links listed.

1) Why not just unplug the wire if you don't want to use it anyway?
2) What do you use to manage wired connection? I though iwd handles wireless part and is a replacement for wpa_supplicant rather than networkmanager, am I wrong about it?
