 Posted: Wed Nov 06, 2024 5:12 am Post subject: Giving wlan0 priority over eth0 |
 |
|
| 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?

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?

I didn't install NetworkManager on this install thus I don't have nmcli as I am just using iwd. I had it working on my previous microsd with NM as it was fairly easy. The problem I've been having with the PI5 on both Arch (using wpa_supplicant) and Getntoo (NM) is the network interfaces freezing up randomly. Sometimes after a half day sometimes after a couple of days. I would like to try to make it work with iwd but I'm not sure if this is doable. |

1. It seems any large emerge doesn't do well with wifi so I like to keep plugged in and then I can just up or down the network interface I don't want to use.
2. I'm not sure what manages eth0. Naturally the wifi is managed by iwd. This is probably why I can't set a priority since they are two different managers. I'll just try to work off wifi and see how it goes or buy a new wall outlet ethernet connection with a high speed one as my current one is 100MB/sec |
