Resetting ethernet config on asus rt-ax53u

I have installed openwrt 23.05.2 on my asus rt-ax53u router and as stated in the wiki ( the WAN doesnt work and I have to reset the ethernet config. So how exactly do I reset this ethernet config? This is my first time using openwrt... The wiki has this link as a reference: but I still do not know what to do.

Reading the GitHub case, and device wiki entry, seems a device reset is required ?
It's done in the same menu as where you upgrade your device, with a new version of Openwrt.

Btw 23.05.3 is out.
