PPPoE failed to attempt connection even after adding right credentials

Installing and Using OpenWrt
1

People help!

I have my Phicomm device (ST-W521IN-DUAL) and OpenWRT (24.10.4 k2g) firmware.
I had been stuck on PPPoE configuration on wan/wan6 interfaces, says in first seconds: unknown error (USER_REQUEST), then "connection attempt failed".

Here is my logs, and configuration

Is this a supported model? If you are running manufacturer firmware instead of an official image from downloads.openwrt.org results may vary and we on this forum can't offer much advice.
As general advice, "Timeout waiting for PADO packets" means there is no link at all to the ISP. Perhaps you need a VLAN tag going to the modem, modem is not linked with the ISP, etc.

K2g is completely supported.

What version is there in
ubus call system board ?

To get more details of pppoe connection add the following line in pppoe section in /etc/config/network

option pppd_options debug

And try starting the connection again. then show us the log (you can hide last 3 parts of your MAC address)

As already said, you have to select VLAN since pppoe concentrator discovery is not replied.

I wanna say before all, sorry for my low-leveling knowledge question

How i should to do this?

You must read the secifications of your connection at your provider, or their supplied CPE router.

Start by asking your ISP what is needed to make a connection, often you need set a vlan tag on the interface.

If a vlan is not needed and only username/password then power down the modem and power down the router, after 5 minutes power up the modem and after 5 more minutes power up the router that sometimes helps
