I am setting up a new AP. RB-333 running 900 Mhz. I want it setup like my 2.4’s with PPPoE. I have duplicated the setup with the only difference I can see 2.4’s are ROS 2.9.46 and the new one is 3.3. can anyone indicate what the error means? It occurs during PPPoE login. I get an authentication and a immediate disconnect.
