Error: "no PHY for ifname eth0"

Installing and Using OpenWrt
1

Hi, I have a problem with connecting my router via Ethernet cable to the network. I need to use authentication and I am trying these 2 guides:

  1. https://gist.github.com/LupusArgentum/0a03106c0484480376b5878ca4f30761
  2. https://freedium.cfd/https://medium.com/@herman.daniel/run-openwrt-on-your-router-and-connect-to-eduroam-via-ethernet-12f6e7e40344

When I run the command "wpa_supplicant -D wired -i eth0 -c /etc/config/wpa.conf" or "wpa_supplicant -D wired -i wan -c /etc/config/wpa.conf" it always gives me the message "no PHY for ifname wan". I haven't found any solution to this problem on the internet so I'm trying it here. I don't know where exactly the problem is, if the router doesn't know the port or if it is named differently. My router is TP-Link Archer AX23 v1.2.
Thanks for the advice.

possibly replace eth0 with wan?
