Il y avait cette commande à tenter :

En complément de mon message précédent, le conseil d'un expert du wifi sur Ubuntu, chili555 :
Le 24/12/2020, chili555 a écrit :
I also recommend that you set your router to a fixed, non-overlapped channel:
Je vous recommande également de régler votre routeur sur un canal fixe, sans chevauchement :
Extrait de l'article a écrit :
Pourquoi les canaux 1, 6 et 11 ?
Dans la bande 2,4 GHz, 1, 6 et 11 sont les seuls canaux qui ne se chevauchent pas. La sélection d'un ou plusieurs de ces canaux est une partie importante de la configuration correcte de votre réseau. Actuellement, de nombreux routeurs sans fil sélectionnent automatiquement le canal pour vous lors de la configuration initiale, où, selon votre environnement sans fil, cela pourrait entraîner des vitesses WiFi lentes et des interférences.
