Ethernet not working on Manjaro 21.02 Raspberry Pi 4 Minimal

I did not disable it. My installation is basically just fresh out of the box

Activating it with timedatectl set-ntp true did not help

I just installed a fresh vanilla Manjaro ARM minimal on a SD card on my RPI4, i have chosen the same parameters as you, even the timezone Asia/Hong_Kong.
I had no issue with internet connection, i get an ip address automatically.
So, i doubt the issue comes from Manjaro, or it’s out of my competences, i can’t help you more.

What options or settings have you got on the router side ?

I just realized that the system time is off by several months

Active: active (running) since Sun 2020-10-04 02:13:07 HKT; 4min 32s ago

I will now somehow try to set the time manually, then hopefully obtain a DHCP lease which then allows NTP to do its job properly.

24

Damn, and yet, i did not notice your system time was still in 2020 despite your screenshot you did some days ago…

25

that did not do the trick. I flushed the card and installed ubuntu 20.04 lts which complained about the ethernet adapter being in power safe mode. I disabled power saving through /sys/class/net/eth/power/config

then I installed raspbian 64-bit which assigned a 169.x.y.z and ultimately also failed to connect to the network.

I then tried to set up wifi which was softblocked. after configuration wpa_cli failed to find any networks so I just trashed the raspberry and am going to use a proper desktop for the job.

My 2 cents.

I have a couple of Manjaro minimal installs on RPi4, one uses wifi, the other wired ethernet.
For the wired network, the only thing I needed to do was to create:

/etc/systemd/network/10-wired.network

[Match]
Name=eth0

[Network]
DHCP=yes

And then reboot.

I used a similar setup for the wireless. No additional software or configuration required.
