Comme le titre l'indique, lorsque je suis sur eduroam, ma connexion internet s'interrompt au bout d'un certain temps (généralement au bout de quelques minutes lorsque j'ai beaucoup de trafic, par exemple pour des réunions zoom, et au bout d'une heure lorsque le trafic est moindre). L'ordinateur portable reste connecté au wifi mais aucun site web n'est accessible et je ne peux pas non plus faire de ping sur les serveurs DNS (bien que les connexions existantes avec Netflix, par exemple, fonctionnent encore parfois). Je n'ai pas ce problème sous Windows.
La sortie de journalctl lorsque cela se produit est la suivante

Il s'agit du même problème que celui décrit aquí mais la solution proposée ne fonctionne pas pour moi. Je suppose que c'est parce que ma configuration réseau Ubuntu est différente de leur configuration Arch, donc si quelqu'un peut me dire ce qu'il faut changer dans ma configuration pour qu'elle corresponde à la configuration ("par défaut") d'Arch, j'apprécierais également.
Edit : Le problème est causé par le changement d'APs, donc fixer le BSSID pour le réseau dans la configuration de Gnome résout les déconnexions, mais ce n'est probablement pas optimal....
Edit 2 : Il semble que mon adaptateur wifi soit reconnu comme Killer Wi-Fi 6 AX1650i 160MHz Wireless Network Adapter (201NGW)
même si c'est un Intel AX201. J'ai également trouvé ces lignes dans mon dmesg :
[ 4.382504] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-Qu-c0-hr-b0-56.ucode failed with error -2

[ 4.387716] iwlwifi 0000:00:14.3: Direct firmware load for iwl-debug-yoyo.bin failed with error -2
Cela signifie-t-il que le mauvais micrologiciel est chargé pour l'appareil ?
