We have the following problem in connection with iPAD/iPhone or MacBook with Cisco WLC: On the LAN connection IEEE 802.3, which is currently in the same VLAN as the IEEE 802.11ac WLAN SSID, the search domain is evaluated by the DHCP server as option 119 and is also displayed on the device and works, but if we use the device in IEEE 802.11 ac Register SSID, this parameter is not evaluated, can it be released on the WLC?
The DHCP Server is a Windows 2019 Server OS

So you're saying the Macbook gets option 119 when connected to LAN but not when connected to WiFi?
Have you done a packet capture to confirm that the DHCP server is sending it in both cases?
How is the DHCP configured for your WLAN?
Are you using DHCP proxy on the WLC?
If you already have DHCP configured on the LAN then why not simply bridge the DHCP to the LAN and let the LAN handle it instead of using the WLC DHCP proxy?
