@DanielDaniel

LCP is Link Control Protocol.

I think it means your connection is dropped.

I think this error code must be provided by zyxel... no?

and I totaly foget but in the logs I can see:

Hi @DanielDaniel

I think that PPP LCP Reason:0 lower down is telling you that the LCP layer of the PPP protocol has been terminated, probably by the other end of the connection you are trying to make.

I think that the root cause is indicated higher up in the log, namely PPPOE authentication failed.
    - this means that the user name and password in your router are not recognised at the other end probably by your Internet Service Provider (ISP).

I think that you need to confirm that you have the write user name and password combination set-up in your router that matches your ISP.
    - I have had this problem myself when I moved house.

Kind regards,
