how to make my pi 4 prefer wifi over ethernet

google · Dec 28th 2021

Hi everyone I run raspbian lite os on my raspberry pi 4.

I installed openmediavault on it. I have both wifi and ethernet connected to my pi 4.

ethernet is just for the local network. it doesn't have internet access.

wifi has internet access.

if eth0 is removed from omv network interfaces

I can ping, update, etc.,

but when I add eth0.

I cannot ping any sites, cant run any updates. my pi 4 is preferring eth0 for the internet.

I still want to connect to the ethernet. I want my local devices to talk to each other.

how do I set my pi 4 to prefer wifi for the internet?

any help would be appreciated.

Version

6.0.5-3 (Shaitan)

Processor

ARMv7 Processor rev 3 (v7l)

Kernel

Linux 5.10.63-v7l+

interface eth0

metric 300

interface wlan0
metric 200

adding this in /etc/dhcpcd.conf should fix the issue.

but it is my understanding that omv doesn't use dhcpcd.conf file.

so how do i fix this in omv?
