[SOLVED] Unable to connect to or ping most websites

** This has been solved, the issue was not having configuration files set up for systemd-networkd **

Fresh install. I think this is DNS related.

After the installation of the base system, I installed iwd as a network daemon.

Pinging google.com over wi-fi works fine and it loads in the browser too, however, when trying to ping 8.8.8.8, I get the following error message:

Network is unreachable

Pinging duckduckgo.com or any other website (besides facebook, youtube, archlinux.org and a few others) gives me:

Name or service not known.

Web browsers refuse to load those sites too.

Interestingly enough, I'm able to resolve any website via

$ getent hosts anywebsite.org

However entering the IP to browser doesn't load the site, with Firefox stating Unable to connect.

I'm even able to install any software with pacman with only occasional

Could not resolve host

error message on some mirrors.

After doing some research, I created a symlink with:

ln -sf /run/sytemd/resolve/stub-resolv.conf /etc/resolv.conf

Similar situation to the one described above was the case with the live USB too.

My hosts file:

127.0.0.1		localhost
::1			        localhost
127.0.1.1		archsystem.localdomain archsystem

resolv.conf:

# Generated by resolvconf
domain home
nameserver 192.168.0.1
nameserver 2001:730:3ef2::10
nameserver 2001:730:3ef2::11

Changing the first nameserver entry to 8.8.8.8 didn't help.

stub-resolv.conf

nameserver 127.0.0.53
search home

*comments omitted

My systemd-resolved is up and running.

Note: Before I realized this might be DNS related, I tried to reduce the  MTU  to something like 1400 bytes, however this helped not.

Re: [SOLVED] Unable to connect to or ping most websites

If you cannot ping 8.8.8.8 or reach other domains by IP, this is not a DNS issue. The limited IP resolution probably happens out of the cache.
Post the outputs of

ip a; ip r

and a complete journal from one boot, please.

Re: [SOLVED] Unable to connect to or ping most websites

You've no route and no IPv4 address, wild guess:

systemctl list-unit-files --state=enabled

?

Nope.
What do your /etc/systemd/network/* configs look like?

Re: [SOLVED] Unable to connect to or ping most websites

iwd.service                                                              enabled
.....
systemd-networkd.service                               enabled

Maybe a conflict between iwd & systemd-networkd ?

Re: [SOLVED] Unable to connect to or ping most websites

Afaiu the systemd-network wiki page you actually *have* to be running either the iwd or the wpa_supplicant service, ie. it won't establish the carrier itself?

Re: [SOLVED] Unable to connect to or ping most websites

Most of my network knowledge comes from the OSI 7 layer model which was designed when wired connections were normal and wifi non-existant.

I used wifi / wpa2 through frontends like netcfg , windows network management, router webinterfaces and never looked deeper into them.
I checked things and realise now iwd/wpa_supplicant  function on layer 1 + layer 2 and don't have  a counterpart in wired connections.

systemd-networkd operates on layer 3 and above and needs other stuff to establish layer 1 & 2 connectivity.
iwd & wpa_supplicant are implementations that play  a role in provide that connectivity.

TL;DR :
a conflict between iwd & systemd-networkd is impossible by definition.

@Lone_Wolf:

Thank you for your input.

@seth:
My /etc/systemd/network seems to be empty.
Have I missed something on wiki?

Re: [SOLVED] Unable to connect to or ping most websites

iwd will only provide you with access to the AP, ie. it establishes the "cable", so to speak.
You'll still have to configure the interface (or let it configure by dhcp) and in case you want to use systemd-networkd for that job, tell it to do so.

Re: [SOLVED] Unable to connect to or ping most websites

Thank you so much, this has solved the issue.

Now the question is, why certain bigger sites worked and minor/local didn't.

Re: [SOLVED] Unable to connect to or ping most websites

Afaiu only "getent hosts anywebsite.org" worked (and apparently only for a limited set of webpages)?
That's only an internal response from the resolver, ie. lilkely resolved's cache.
