Hello @karakobra1 :wink:

Probably because Manjaro has no DNS Cache by default and requests every IP of any Domain every time.

File: /etc/NetworkManager/conf.d/dns.conf

[main]
dns=dnsmasq

Then reload the config:

sudo nmcli general reload

Test it:

drill manjaro.org

Take look at query time and the server must be now: 127.0.0.1

This looks like a custom dns - not even a router - but definately something custom.

You need to retrace your changes to get back to a working system

4

yes it is 127.0.0.1 so can you explain me whay we’ve done here and also is this aproblem ```
systemd-networkd is not running, output might be incomplete.

5

how can I retrace the changes?

6

only you know … what changes you may have made … but it most likely connected to your DNS - perhaps a half configured or broken VPN tunnel

7

NetworkManager is the default on Manjaro and systemd-networkd is another network service. Both conflict with each other, so only one can run.

:question::question::question:

Manjaro doesn’t use systemd-resolved, it uses the glibc resolver.

Are you using some ancient router? Wireless-N is from 2008 and you don’t even have IPv6 support.

Post output of inxi -nz.

Also drill www.google.com and same again for a website that you have problems connecting to.

Network:
  Device-1: Intel Comet Lake PCH-LP CNVi WiFi driver: iwlwifi
  IF: wlo1 state: up mac: <filter>

My guess is that the problem is a crappy DNS server on the router. I don’t why your phone works ok with it, perhaps you changed DNS servers on that in the past? You can manually set DNS servers for your connection like this;

nmcli conn modify “wifiname1” ipv4.ignore-auto-dns yes
nmcli conn modify “wifiname1” ipv4.dns “1.1.1.1 8.8.8.8”
nmcli conn down “wifiname1”
nmcli conn up “wifiname1”

1.1.1.1 = Cloudflare
8.8.8.8 = Google

If you don’t want to use them then use your ISP’s dns server addresses instead.

13

ok then all the information revelead by systemd-resolver is useless in this case as well as etc/resolv.conf right?

14

I think Android uses a Google-powered DoH server (If I recall that correctly) for DNS, unless you change and customize it. So it might be that. I don’t know if it’s the same for iOS or not.

15

Yes.

No, but etc/resolv.conf is managed by Network Manager so don’t edit it directly.

That would make sense.

16

It would yes. I know I had to customize my settings for it so that it used my PiHole instead of Google’s thing.

17

thanks btw it seems running better now, is there a resource that I can learn more about linux networking and commands etc. ?

18

The Archwiki is your friend:

https://wiki.archlinux.org/title/Network_configuration

19

thx for example is there a way to find out which network manager is used

20

As far as I know, by default Manjaro uses NetworkManager and resolvconf. But I don’t know other than knowing your system. (In this case, the defaults. Don’t worry, I’m using the defaults myself.)
