Bien, après vérification des paramètres,
le modem routeur fourni est en mode bridge (et me donne accès lorsque je le connecte directement à un port ethernet du PC)
le routeur est en mode DHCP auto
et le modem est connecté sur le port internet du routeur
J'ai activé le journal, rebooté le routeur, rebooté le modem et laissé tourner pendant 1 h.
Résultat de la consultation des journaux :

J'imagine que c'est là, le plus intéressant mais je n'y comprend pas grand chose...
Les MAC correspondants sont les suivantes :
00:04:20:12:8B:C5 : Squeezebox
A0:21:B7:B8:CF:2A : Wifi extender Netgear
00:16:DC:65:C5:C8 : Telephone wifi
C8:60:00:9F:6E:1B : 1 des PC relié en filaire au routeur
Je ne sais pas si ça peut aider mais la led du modem/routeur correspondant au port connecté au routeur (les autres sont vides, bien sur...) reste orange au lieu de passer au vert lorsqu'une activité normale est détectée.
Est-ce que ça te dit quelque chose ?
Merci d'avance de ton temps !
