Good evening, I'm writing to you because I'm encountering a problem on a small lab I've created to set up a wifi configuration with a terminal. I'm attaching the infra.
A very simple infra, on my level 3 switch I've set up a vlan that I've assigned to all my interfaces in connection with the other equipment
FastEthernet0/1 interface
switchport access vlan 10
switchport mode access
and this for the 3 interfaces, I've also declared a dhcp pool in 192.168.10.0, mask /24, default router 192.168.10.254 (a vlan 10 interface that I've addressed to act as a gateway).
The dhcp config:
ip dhcp pool lan
network 192.168.10.0 255.255.255.0
default-router 192.168.10.254
option 43 ip 192.168.10.1
option 150 ip 192.168.10.1
And the interface declaration
interface Vlan10
mac-address 00d0.9779.8201
ip address 192.168.10.254 255.255.255.0
my machines now receive their dhcp addresses, are in the right address pool and I can ping all the machines from my admin post.
However, when I set up my controller, it doesn't find my terminal, it doesn't connect to it.
I know I'm doing something wrong but I can't find it, I've been pulling my hair out for hours, I hope you can help me.
Thank you very much for your attention and help

I think the actual config (show run-config or show run-config startup) from the WLC would be more useful than 2 screenshots from the GUI?
The thing that caught my attention is the software version 8.3.111.0 which is really VERY old - there will have been thousands of bug fixes since that release!
I would first upgrade it to 8.5.182.11 (link below) and then upgrade to current release 8.10.190.0:

What model of AP are you using?
