[SOLVED] NetworkManager disconnects from one Eduroam connection

c0manch3 · 2025-04-15 09:03:20

Let me describe the problem and add the log file. Btw, I am quite new with Arch linux and this is my first post, so let me know if any other log would be useful; until now I managed to solve all problems I had by checking the output of journalctl, reading the wiki and searching in the forum for posts about similar issues. However, this time I face a log that I am struggling to interpret.

DESCRIPTION

I use NetworkManager to manage the wifi connection. I can connect without any problem to many points, like at home, to my phone's hotspot, etc. However, the connection to eduroam in my workplace does not work anymore (it used to work until some days ago, and I have not updated any package in the meantime). I can connect to eduroam in some other institutions.

LOG

This is the log (since the last boot) generated by journalctl -u NetworkManager . I do see that there is a warning (related to a dns?), but I don't have enough experience to interpret it.

I have seen a couple of posts like this or that which could be related, also recommendations on the wiki about MAC randomizatoin , but I'm not sure if any of them is related to my problem, so I would like to get your opinion before making a mess trying on my own things I really don't know lot about.

I would appreciate your feedback, and I apologize beforehand for not being to formal; it's my first day :S

This warning is issued by systemd-resolved about trying to send mDNS updates and realizing that "wlan0" is managed (supposedly by NetworkManager).

Since the log looks like a successful connect and NetworkManager detects concurrent DNS management

Apr 15 10:06:07 archlinux NetworkManager[646]: <info>  [1744704367.3858] dns-mgr: init: dns=default,systemd-resolved rc-manager=symlink

can you ping an IPv4 address while connected to eduroam?

ping 8.8.8.8

If yes, can you ping "dns.google"?

ping -4 dns.google

c0manch3 · 2025-04-15 11:34:41

 ping 8.8.8.8

works properly. However,

 ping -4 dns.google

does not. It prints no output.

This looks like a DNS problem. If you want or need to keep systemd-resolved for DNS management (NetworkManager can do it by itself) then you should tell NetworkManager:

# /etc/NetworkManager/conf.d/dns.conf      
[main]
dns=systemd-resolved

and make sure "/etc/resolv.conf" is a link to the correct stub file:

ls -la /etc/resolv.conf
lrwxrwxrwx 1 root root 37 Dec 12 18:22 /etc/resolv.conf -> /run/systemd/resolve/stub-resolv.conf

c0manch3 · 2025-04-15 13:50:19

I have disabled the default dns resolver of NetworkManager following your indications. Now I see that dns=systemd-resolved in the output of journalctrl -u NetworkManager. The warning in the log of my initial post is still there, and I keep being unable to resolve webpages by their domain names (for instance, ping -4 dns.google does not work yet).

I have also tried the other way around: I have followed the the indications here to turn give up systemd-resolved and use exclusively the default of NetworkManager . With this, I see in the output of journalctl -u NetworkManager that dns=default, as expected. However, I am still unable to resolve domain names.

Any idea of what could be going on?

-thc · 2025-04-15 14:17:22

If you want to get rid of the (mostly cosmetic) warning, disable mDNS inside systemd-resolved:

#  /etc/systemd/resolved.conf
MulticastDNS=no

Let's take a look at the state of your DNS management.

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-45s | %s\n", $(NF-0), $(NF-1)) }' | sort -f
ls -la /etc/resolv.conf
cat /etc/resolv.conf
cat /etc/nsswitch.conf (the line "hosts:")
resolvectl (only with active systemd-resolved)

c0manch3 · 2025-04-15 14:20:38

Let me follow up by proving the output of journal -u NetworkManager for a boot in which I first connect to eduroam (with dns=defaul, so I am not using systemd-resolved), I realize that I can not solve domain names and I connect to my phone's hotspot named "vivo Y52 5G" (my phone is connected to eduroam). Once connected to my phone, I can solve domain names.

You have concurrent active network managers (systemd-networkd and NetworkManager). Stop and disable systemd-networkd.

If you want to use NetworkManager alone you should stop and disable systemd-resolved too.

This seems to work. I could resolve domains once connected to eduroam, and now I checked that it still works at home (nothing broken). I will check again that it works when I get back to my office, and if it does, I will mark it as SOLVED.

Thank you very much for the help, -thc!
