[SOLVED] I can ping my router, but i can't ping outside servers.

Hello. I started to hate Ubuntu because they gave me continually gtk errors. So i have installed arch today. While i was installing, i could reach internet via ethernet cable. After reboot, ping started to give me error " ping: connect: Network is unreachable" while i still using ethernet cable.

Default gateway address; 192.168.2.1/24

ip link show:
2: enp12s0: <BROADCAST, MULTICAST, UP, LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
link/ether 00:2b:.....:0d brd ff:.....ff
3: wlp0s20f3 <BROADCAST, MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether a8:7e.....:75 brd ff:....:ff
ip address show (i have added static ip):
2: enp12s0 inet 192.168.2.160/24 brd 192.168.2.255 scope global enp12s0
networkctl:
enp12s0 ether routable unmanaged
wlp0s20f3 wlan off unmanaged
networkctl status enp12s0:
State: routable (unmanaged)

Driver: r8169
Duplex: full
Port: tp
Address: 192.169.2.160
Activation policy: up
Required for Online: yes
enp12s0: Link UP, gained carrier, gained IPv6LL

Used commands;

networkctl up enp12s0
networkctl reconfigure enp12s0
networkctl reload enp12s0
There were no outputs.
networkctl forcerenew enp12s0
Failed to force renew dynamic configuration of interface enp12s0: Interface enp12s0 is not managed by systemd-networkd
ip link set wlp0s20f3 up:

I have restarted systemd-networkd.service
Under /usr/lib/systemd/network , there are .network .example files and a .link file.

I writed

rfkill unblock all ; rfkill --output-all

1 bluetooth ideapad_bluetooth Bluetooth unblocked unblocked
2 bluetooth hci0 Bluetooth unblocked unblocked
3 wlan phy0 Wireless LAN unblocked unblocked
ip link set wlp0s20f3 up (This time code worked)
ip link show
3: wlp0s20f3 <NO-CARRIER, BROADCAST, MULTICAST, UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT .....

I restarted systemd-networkd.service with systemctl. Still same. I can ping my router. But can't 1.1.1.1 or 8.8.8.8

Rebooted, still same. I can't reach outside servers.

Note: Before these all, I finished my installing. And rebooted. I decided to download xorg and i realized i can't connect internet. There were loopback ints, ignored.

SOLUTION:
I have added two files into /etc/systemd/network

20-wired.network

[Match]
Name=enp12s0

[Network]
Address=192.168.2.160/24
Gateway=192.168.2.1
DNS=192.168.2.1

25-wireless.network

[Match]
Name=wlp0s20f3

[Network]
Address=192.168.2.161/24
Gateway=192.168.2.1
DNS=192.168.2.1

And i have connected to internet finally.

Please use code tags, not quote tags.
Most importantly:

ip r

Interface enp12s0 is not managed by systemd-networkd

i have added static ip

Why?
Since systemd-networkd isn't managing the interface, how do you (intend to) manage the network at all?

f-elixxx · 2021-08-05 20:38:13

1. Can you ping other devices in your local network?
2. I think that you should add a config file when using systemd-netoworkd e.g. https://wiki.archlinux.org/title/System … n_examples
3. I would recommend using NetworkManager especially if you are plan on using a desktop environment, VPN's ...

I will be more careful next time. Sorry. I have added a static ip for also my wireless device. I realized my computer can't receive ip and dns. So i have added static IPs via "ip address add" and DNS to resolv.conf

ip r:
192.168.2.0/24 dev enp12s0 proto kernel scope link src 192.168.2.160
192.168.2.0/24 dev wlp0s20f3 proto kernel scope link src 192.168.2.161 linkdown

2. I looked it and i found it very complicated so i prefer to use NetworkManager.
3. I would like to use NetworkManager! But i can't reach internet so pacman doesn't work. Is there a way?

Thanks for advance.

You don't have a default route out of your local home network.
The question remains as to how (services, and their respective configuration) you set up your network.

hmet_ust · 2021-08-06 11:23:31

Thanks for your all advices. I have written some .network files into /etc/systemd/network and problem solved. Thanks again to you all.

I know that the problem is resolved by know but for future reference just boot into the live usb drive again, mount the root partition to /mnt and do

arch-chroot /mnt

If you had an internet connection during the installation you should have one now as arch-chroot as it exposes the resolv.conf file to the changed root (see: https://man.archlinux.org/man/arch-chroot.8).
