an einem 1793VAW mit VLAN-Modul aktiviert, hängen via ZyXEL VLAN Switch zwei Unifi UAP-AC-PRO, die mehrere SSIDs ausstrahlen. Der 1793VAW ist der DHCP Server für einige der Netze, auch für das hier beschriebene G0011 genannte Netz (ein WLAN-Gastnetz). Die DHCP-Range ist 100 Adressen breit, von denen ca. 30 laut DHCP-Tabelle belegt sind.
Ich brauche Hilfe zur Eingrenzung und Klärung, warum ein bestimmtes Device in diesem Netz keine IP-Adresse zugewiesen bekommt.

Gleichzeitig sind eine Reihe anderer Devices in dem WLAN-Netz aktiv.
Ebenso kann ich mit dem S7 auf ein anderes WLAN der beiden UAP-AC-PRO in einem anderen Netz verbinden, das der 1793VAW managed. Das S7 ist also nicht generell auf dem DHCP-Server des 1793VAW blockiert.
In einer ähnlichen Konstellation mit einem 1821n / VLAN / ZyXEL Switch / UAP-AC-PRO / Gast-WLAN habe ich mit dem selben S7 ebenfalls keine DHCP-Probleme bei der Verbindung mit einem Gast-WLAN.
Auf dem UAP-AC-PRO treten keine Ereignisse auf. Von der Seite also keine Hinweise zur Eingrenzung der DHCP-Probleme.
Der Trace des 1793VAW ist für mich so nicht schlüssig, dass ich einen weiteren Ansatzpunkt daraus ziehen könnte. Vielleicht könnt ihr mal einen Blick darauf werfen und mir einen Tipp geben, wie die Ursache weiter eingegrenzt werden kann?
