Hello!
On the WAC540, you need to keep the management VLAN untagged so the AP can reach Insight, and then tag any SSID VLANs on the switch port. If clients connect but get a 192.168.10.x address, that means there’s no DHCP server on the VLAN you assigned to the SSID, so they self‑assign. The fix is to configure the switch port as a trunk with the native VLAN untagged and the SSID VLANs tagged, confirm the SSID is mapped to the right VLAN in Insight, and ensure DHCP is available on that VLAN. That way, WiFi clients will join the correct VLAN and get proper IPs.
