Zyxel 642R-11

These messages are produced in response to PPPoE. Is err code missing a digit or is it really -300

Basically, you must verify that PPPoE settings are correct. Typically, username should be in the form user@context For password, sometimes an unvisible leading blank is entered if you do the setup from the web interface. Make sure the field is completely blank and does not have any hidden spaces.

If setup from menu 4 does not work. Go to menu 11 for more detailed setup. Sometimes service provider will only accept CHAP or PAP authentication. Try both ways. Finally, some PPPoE providers need a particular "Service Name" to be used. Normally blank will cause router to pick the first service name available but sometimes on the same PPPoE server may route to different service providers based on service name and you may be trying to connect to wrong service provider. So, a particular service name is required. Your ISP can probably tell you.

So you need to specify correct service name if this is the case.

If you go to menu 24.8 you can initiate ppoe connection from command line using:

dev dial 1

To turn pppoe debugging enter the following CI command:

poe debug on
or
poe debug 1

To turn it off:
poe debug off
or
poe debug 0

Please note that for "dev dial 1" to work your router must not be currently dialing/connecting. So, you have to enter the following command below to disconnect/abort existing PPPoE dialing first and quickly enter dev dial 1 next.

To drop PPPoE connection:

poe drop poe0

Good luck, I dont have PPPoE connection so I hope these commads do work for you as I had tested it on ZyXEL P314 last time.

Nice thing about manually dialing and PPPoE debugging is that you can find out what services are available as well.
