Frequent eduroam Disconnections

[merlino]

Hello, I’m experiencing (very) frequent disconnections to eduroam on my Manjaro Linux system. I regularly connect to eduroam using other devices, including a Windows machine, an Android phone, and an iPad. Unfortunately, only the Linux setup has consistent issues.

I attach the output of the following commands for reference:

dmesg | grep wlo1

I’ve configured eduroam using the official CAT tool, following all provided steps. To work around authentication issues, I had to set phase1-auth-flags=32 to downgrade TLS security, due to limitations with the university’s older radius server.

Below are my current configurations in eduroam.nmconnection:

[connection]
id=eduroam
uuid=<UUID Hidden>
type=wifi
permissions=user:<user Hidden>:;

[wifi]
ssid=eduroam

[wifi-security]
group=ccmp;tkip;
key-mgmt=wpa-eap
pairwise=ccmp;
proto=rsn;

[802-1x]
altsubject-matches=DNS:edu-radius1.universitydomain.edu;
anonymous-identity=anonymous@universitydomain.edu
ca-cert=/home/<user hidden>/.config/cat_installer/ca.pem
eap=ttls;
identity=name.surname@universitydomain.edu
password=<password hidden>
phase1-auth-flags=32
phase2-auth=pap

[ipv4]
method=auto

[ipv6]
addr-gen-mode=default
method=auto

[proxy]

Has anyone else experienced similar issues with eduroam on Manjaro? Any ideas on how to resolve this or insights on improving connection stability would be greatly appreciated!

Thank you!

First I wonder about

@merlino

ca-cert=/home/<user hidden>/.config/cat_installer/ca.pem

Should it not be ca_cert (underscore instead of dash) ?

Then I wonder about your resolv and resolv.conf.

As it has been noted problems there can have an effect on eduroam.

It may be worth mentioning that for a long time manjaro shipped the old openresolv, but now relies entirely on NetworkManager, and I usually suggest systemd-resolved.

pacman -Qsq resolv
cat /etc/resolv.conf

Anyhoo, you might have some help from this thread, or particularly this post:
https://bbs.archlinux.org/viewtopic.php?pid=2104709#p2104709

Which you seem to have already applied, but theres some other bits there including

though it seems to be a bit finicky, and doesn’t actually work unless I run

nmcli connection up eduroam

from the command line.

[merlino]

Thank you for the answer!

@cscs

I’m not sure about the name format, but this is how the eduroam installation tool configured it and I can find the certificate there. Since I am able to connect, I assume it’s set up correctly.

I can connect apparently without problem (even automatically when I start my pc) but then often happen that the network is unstable and disconnect frequently. Basically, it disconnects and then, it fails trying to reconnect.

Running the command:

@cscs

cat /etc/resolv.conf

gives:

# Generated by NetworkManager
search universitydomain.edu
nameserver 151.100.4.2
nameserver 151.100.4.13

I’m not sure about resolve, should I install it? When I run the command, this is the output:

$ pacman -Qsq resolv
libmicrodns
openresolv
ruby

@cscs

nmcli connection up eduroam

I tried this, but the connection continues to fail while attempting to reconnect.

Thanks a lot for the help!

Wifi disconnections? Try this:

RTL8822CE Instability even with newest kernel

You can try two workarounds. Turn off wifi power save first. Create .conf file: sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf And copy these two lines inside it: [connection] wifi.powersave = 2 If the issue remains, turn off Mac Randomization. Create .conf file: sudo nano /etc/NetworkManager/conf.d/disable-random-mac.conf Copy these two lines inside: [device] wifi.scan-rand-mac-address=no Hope this can solve your problem.

[merlino]

@Arrababiski thank you for your help!
I’ve now disabled the power-saving feature.
Regarding the randomized MAC address, is it possible to disable it only for the eduroam network? This way, I can keep the random MAC address for any other network I connect to.

Careful if you connect to eduroam network in a library university, cause where I work all students suffer disconnections all day long due to wifi overloaded. Think about asking librarians or people around you.

[merlino]

Thank you for your answer, but I’m not quite understanding your point. What exactly should I ask the librarians or people around me?

For context, I generally don’t experience issues with my other devices on this network. Although Wi-Fi might not be the most stable option for others either, they don’t seem to face the same disconnection problems that I’m encountering.

[lopasilver]

Ok, Just want to alert you that connection might be unstable by itself, at least in the library I was in France, it was a recurrent problem.

Good question… I don’t know. Let’s see if someone with more knowledge can give us an answer.

Thank you for your response; unfortunately, no one else has answered yet.
