Can connect to wifi, but not the internet

Network card: Qualcomm Atheros AR9485 Wireless Network Adapter.

ping archlinux.org outputs "Destination unreachable: No route"

I was perfectly able to connect to the very same network with my phone (and make this post with it).

Can anyone help me?

You have no IPv4 address and only have a local IPv6 address.

How are you connecting to the WiFi? Are you just using wpa_suplicant?

It looks like you connected, but there is no IPv4 address. You probably did not configure a dhcp client to receive an IP and valid routes.
IPv6 is also not configured, so maybe your network does not support ipv6 or requires dhcpv6.

If you use iwd you can configure it to perform the dhcp network configuration, otherwise choose something else: https://wiki.archlinux.org/title/DHCP#DHCP (either a client or a network manager)

Just checked my nm-connection-editor and it said that both my IPv4 and IPv6 were automatic. So what went wrong?

Look through your logs for DHCP and see if there is anything relevant. Is this a network you administer?

I believe the "no global addresses for default route" is the culprit for the issue. Do you know what does this mean?
Also I do not administer this network.

dhcpcd log?
nm-connection -editor?

Smells like multiple services also.

So which one should I disable?

Every network daemon except networkmanager...

And read seth's link.

I have dhcpcd running in the background now. If I kill it, everything crashes, so I don't know how to kill it without screwing myself over

seth · 2022-03-25 15:29:27

Everything? Like you house collapsing and the stars dropping out of the sky?

https://bbs.archlinux.org/viewtopic.php?id=57855

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

And as pointed out before, the ath9k driver has a massive bug in the current kernel, so you want to downgrade that.

Well, yeah.
You've dhcpcd, iwd, Networkmanager and systemd-networkd enabled - alllowing me post this meme for the second time this week:

Pick one, stop and disable the others.

So I uninstalled iwd and systemd-networkd and my net is getting back even after reboots, thanks!

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
