LuCi does not work over Wi-Fi

I have changed my old Gateway OS system from 3 to version four (OpenWrt) once everything was configured with the LuCI interface, including Wi-Fi. I have done all this with an Ethernet network cable.
Once everything is configured, I have disconnected the network cable, everything goes well and it sends data to the network server. What I can’t do is enter through LuCi or ssh into the IP address of the wifi connection created.
I would appreciate if someone can guide me as to what could be wrong and how to fix it.
Thanks for the help.

You might have put the wifi network in the wrong firewall zone. Is it set to WAN or LAN?

tanks this solve my question.
