How to enable the DHCP leasing distribution on the Wi-Fi interface?

ogogon · January 6, 2025, 2:43am

Colleagues, tell me, pls, what I'm doing wrong. Using LuCi, I turned on the Wi-Fi Interface on my router, set its proud name, set the type of encryption and password. He belongs to LAN. I correctly connect with the router from my phone. But DHCP he does not receive leasing. Cables connected to the LAN-ports are receive.
Where did I forget to put the case in the сhekbox?

It is grateful for the answer in essence.
Ogogon.

That should work by default (WLAN being bridged to the wired LAN), if not you have modified the configuration considerably (so more information needed).

I tried not to change anything in the default configuration. What information do I need to provide?

The usual information would be a start, which should cover most aspects:

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

Colleagues! Thank you for your help!

The problem was in the phone from which I checked the connection. I connected normally from the laptop and am writing this message. Apparently, the old UBports on the phone were capricious.

Thanks again,
Ogogon
