Hello together,

today I wanted to create a new VLAN for IoT devices.
Therefore I created a standard LAN configuration with VLAN 90 and DHCP Server. (I left all checkboxes on default to just get it up running for tests).

Then I created the WLAN also fairly standard with only 2.4Ghz and linked it to my IoT LAN.

However the result is that no device can connect the WLAN. I've checked with two phones and they are always "Connecting" or trying to get an IP address.

The part I don't understand is, that if I connect a Laptop with a patch cable to a switch port and apply the IoT profile there, I immediately get an IP address in the configured range from the IoT LAN, so DHCP seems to work.

If I take an already existing WLAN and assign it the IoT VLAN ID, I can't connect.

There must be something wrong in my configuration that I can't get WLAN working with that specific (or any other newly created) LAN.

P.s. I've also checked the switch port profile of the AP and it is set to (all).

Any idea would be well appreciated.
