How to make Wifi network home in OpenWRT Luci?

Question

Network administration

I encountered OpenWRT for the first time, I don’t see the point in bothering with the settings, there are microtics everywhere.
There is also a stale Tp-link 2043 with Openwrt on board.
What do you need? So that openwrt works like a switch, and shares access to the enterprise network via wifi.
Are there manuals?
As I understand it, we need to insert a cable into any port that is not WAN and combine Wifi into a bridge with LAN.

Answer 1

In OpenWRT, by default, wi-fi and lan are already combined into a bridge.
If there is already a dhcp server on the network, then you need to disable dhcp in the router: Network - Interfaces - LAN, on the dhcp-server tab, check the Ignore interface checkbox.
After that, go to Network - Wifi - Edit, enter the SSID and password.
This completes the setup :)
